It will take place as a Solvay workshop organised by the International Solvay Institutes. Further information about Capra 2026 will be posted in the coming months on https://www.caprameeting.org/ and https://solvayinstitutes.be/home/activities/workshop/ . The Capra meeting is an annual conference on the topic of radiation reaction in general relativity. The primary focus of these conferences is the development of the gravitational self-force approach to model extreme mass ratio inspirals and further our understanding of the two-body problem in general relativity. This is done in synergy with other well-known modeling techniques such as post-Newtonian theory and numerical relativity. The canonical example of an extreme-mass-ratio inspiral (EMRI) is the inspiral of a stellar-mass compact object into a supermassive black hole. Gravitational waves from these systems are a promising target for the future space-based detector LISA. The study of radiation reaction and self-force is not limited to EMRIs, and a range of topics and applications to other areas of gravitational physics have been discussed at past Capra meetings; an example is the scattering of massive particles, which is currently an active area of research. The format of the meeting is an amalgamation of a daily invited review talk, short contributed talks and organised discussion sessions. Following the tradition of past Capra meetings, no registration fee is charged. A contribution of 50 euros to the banquet will be requested at registration for the attendees that would like to join the banquet. Several selected early career researchers will be funded by providing up to 6 nights of accommodation during the conference. Applications will be reviewed by members of the local organising committee and the equity, diversity and inclusion team at Capra. Sincerely, The international scientific committee Leor Barack, Susanna Barsanti, Beatrice Bonga, Alvin Chua, Lisa Drummond, Scott Hughes, Adam Pound, Vojtech Witzany The local organizing committee Geoffrey Compere, Lidia Gomes Da Silva, Marc Henneaux, Loic Honet, Guillaume Lhost, Gabriel Piovano +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.9. School on Gravity: from motion to commotion, Copenhagen, Denmark --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29839 Starting: 2026-06-22 to 2026-06-26 Location: Copenhagen, Denmark Additional Information: https://the-center-of-gravity.com/events/the-school-on-gravity-from-motion-… Contact: sog[AT]the-center-of-gravity.com School on Gravity, Niels Bohr Institute, June 2026 Understanding the gravitational interaction is one of the great scientific endeavors of the 21st century. The Nobel Prize-winning discovery of gravitational waves in 2015, and subsequent detections by the LIGO-Virgo-KAGRA Collaboration, have marked a revolutionary step forward in physics and astrophysics by opening an entirely new window for exploring the Universe. Future upgrades to these detectors, along with upcoming facilities such as LISA and the Einstein Telescope, promise even more breakthrough discoveries that the next generation of scientists will need to interpret. The School on Gravity (22-26 June 2026, Copenhagen) will introduce junior scientists-graduate students and advanced undergraduates with a background in general relativity-to a wide range of foundational topics in the exciting new field of gravitational wave physics. Topics will span from the theory of motion, to new challenges introduced by quantum physics, to the astrophysics of black holes and source modeling for gravitational-wave detectors. The program is as follows: Lectures on Black Holes and Neutron Stars (how, when and where they are born, how they spin, how many, when do they merge, how many merge). Lecturer: Lieke van Son (Radboud University) Lectures on Motion (the two body problem in General Relativity). Lecturer: Julio Parra Martinez (IHES) Lectures on Completing Einstein (why does General Relativity need completion, what type of effects should we be on look out for, where would they manifest themselves). Lecturer: Gustavo Turiaci (U. Washington, Seattle) Lectures on Environments (which type of environments, how do they affect strong field gravity, how do we model them, impact on gravitational wave signals). Lecturer: Laura Sberna (Nottingham University) Please apply at: https://the-center-of-gravity.com/events/the-school-on-gravity-from-motion-… We require submission of a single pdf file containing a two-page CV, up to half a page motivation letter, and a signed support letter from an advisor on letterhead. Deadline: February 01, 2026. The number of seats is limited, so we encourage you to apply as soon as possible. The School on Gravity will take place in the legendary Auditorium A of the Niels Bohr Institute, inviting students and lecturers to challenge current paradigms in gravitational physics in the spirit of the quantum revolution that unfolded in this very room. This is the first of a series of annual school organized by the Center of Gravity (CoG). The members of the Scientific Organizing Committee for the School of Gravity are Vitor Cardoso (Director of CoG), Emil Bjerrum-Bohr, Jose Ezquiaga, Troels Harmark, Niels Obers, Marta Orselli, Alessia Platania, Johan Samsing, Maarten van de Meent, Ziqi Yan.

GW-EM-Nu-2025: Multi-Messenger Science With Indian Facilities-Now and in the Next Decade, Mumbai, India --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29842 Starting: 2025-12-01 to 2025-12-03 Location: Mumbai, India Additional Information: https://scitalks.tifr.res.in/event/9167/ Contact: mma.consortium.india[AT]gmail.com This year marks the 10-years of discovery of Gravitational Waves, which has opened a new window for multi-messenger science. The era of multi-messenger science using signals from astrophysical sources observed in different cosmic messengers such as Cosmic Rays (CRs), Electromagnetic Waves (EW), Gravitational Waves (GW), and Neutrinos opens a new paradigm in understanding the physics governing the Universe over different length scales from the size of a nucleus to the size of the observable Universe. The success of this research frontier relies on the coordinated observation between different existing telescopes/observatories which are observing in different messengers and also on building the next generation telescopes/observatories that can jointly observe signals using different cosmic messengers in the coming years in the frequency range (or energy band) which are of scientific interests based on our theoretical understanding of these astrophysical sources. This conference plans to bring researchers from India working in different areas--instrumentation and theory on the same platform to discuss (i) the requirements and challenges in coordinated observations with existing Indian facilities between different messengers, (ii) key areas of development of telescope facilities and theoretical predictions for enhancing the scientific outcome, (iii) the roadmap for joint observations using multiple telescopes, and (iv) plan for strategically important future telescopes/observatories which will enhance multi-messenger science from India. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.11. Enigmatic Explosions: Observations, Modelling, and Microphysics of Extreme Transients, Santa Barbara, CA, USA --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29873 Starting: 2026-10-26 to 2026-12-18 Location: Santa Barbara, CA, USA Additional Information: https://www.kitp.ucsb.edu/activities/explode26 Contact: francois.foucart[AT]unh.edu We are happy to announce the upcoming workshop "Enigmatic Explosions: Observations, Modelling, and Microphysics of Extreme Transients", at the Kavli Institute for Theoretical Physics at UC Santa Barbara. This is an 8-week program running from 10/26/2026 to 12/18/2026, for which the primary deadline for application is 10/24/2025. KITP encourages stay of at least 3 weeks for most participants, though a smaller number of participants will also be invited for shorter stays. You will find a brief description of the scientific objectives of the workshop below. For information about applications, travel, and housing, please see the KITP website, or contact one of the workshop organizers (Francois Foucart, Raffaella Margutti, Philipp Moesta, Rebecca Surman). The detection of bright electromagnetic (EM) transients powered by neutron star mergers, supernovae, and other extreme astrophysical events associated with compact objects will play a major role in nuclear astrophysics in the coming years. These events act as cosmic laboratories allowing us to study the properties of high-density matter and the origin of heavy elements. Transients may even reveal particle physics beyond the standard model in conditions that we cannot probe on Earth. The rapidly growing number and variety of observed EM transients now regularly challenge our incomplete theoretical understanding of the transient sky. These limitations inhibit our ability to leverage transient observations for high-energy and nuclear astrophysics. Despite significant improvements to the numerical accuracy and microphysics of numerical simulations, the impact of nuclear physics inputs, approximate physical modeling, and the large range in spatial scales and timescales that need to be resolved remain major issues. This program will address these issues with an interdisciplinary group of nuclear, theoretical, computational physicists and astronomers as we prepare for a new era of EM discovery and anticipated experiments on exotic nuclei. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ============================================== 2.

News ============================================== 3.1. New book: Second edition of "A Mathematical Introduction to General Relativity", by Amol Sasane ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/09/02/new-book-second-edition-of-a… Additional Information: https://doi.org/10.1142/14082 The book aims to give a mathematical presentation of the theory of general relativity (that is, spacetime-geometry-based gravitation theory) to advanced undergraduate mathematics students. Mathematicians will find spacetime physics presented in the definition-theorem-proof format familiar to them. The given precise mathematical definitions of physical notions help avoiding pitfalls, especially in the context of spacetime physics describing phenomena that are counter-intuitive to everyday experiences. In the first part, the differential geometry of smooth manifolds, which is needed to present the spacetime-based gravitation theory, is developed from scratch. Here, many of the illustrating examples are the Lorentzian manifolds which later serve as spacetime models. This has the twofold purpose of making the physics forthcoming in the second part relatable, and the mathematics learnt in the first part less dry. The book uses the modern coordinate-free language of semi-Riemannian geometry. Nevertheless, to familiarise the reader with the useful tool of coordinates for computations, and to bridge the gap with the physics literature, the link to coordinates is made through exercises, and via frequent remarks on how the two languages are related. In the second part, the focus is on physics, covering essential material of the 20th century spacetime-based view of gravity: energy-momentum tensor field of matter, field equation, spacetime examples, Newtonian approximation, geodesics, tests of the theory, black holes, and cosmological models of the universe. Prior knowledge of differential geometry or physics is not assumed. The book is intended for self-study, and the solutions to all the 283 exercises are included. The second edition corrects errors from the first edition, and includes 60 new exercises, 10 new remarks, 29 new figures, some of which cover auxiliary topics that were omitted in the first edition. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2. GRG Topical Collection "Hyperboloidal foliations in the era of GW astronomy" completed ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/09/15/grg-topical-collection-hyper… Additional Information: https://link.springer.com/journal/10714/updates/27812030 The Topical Collection "Hyperboloidal Foliations in the Era of Gravitational-Wave Astronomy: From Mathematical Relativity to Astrophysics" grew out of interactions at the workshop "Infinity on a Gridshell" in Copenhagen in 2023. Contributors were invited to expand their presentations into full articles, or submit new research motivated by the discussions. The result is a snapshot of a field in rapid development: papers that solidify the linear theory on fixed backgrounds, push numerical techniques to spectral accuracy at null infinity, clarify the role of conserved charges and regularity at scri+, and take further steps toward fully nonlinear hyperboloidal evolutions without symmetry.

Physics and Astrophysics of Neutrino-Dense Environments, Aspen, CO, USA --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29741 Starting: 2026-01-04 to 2026-01-09 Location: Aspen, CO, USA Additional Information: https://aspenphys.org/winter-conferences/#event5893 Contact: dur566[AT]psu.edu A thorough understanding of neutrino flavor transformation is essential for interpreting observations of neutron star mergers, core-collapse supernovae, and the early universe. Despite its significance, its impact on the dynamics of these events, as well as on their multi-messenger signals and nucleosynthesis yields, remains poorly understood. This hinders our ability to connect kilonovae observations, including recently obtained James Webb Space Telescope (JWST) spectra, with the nuclear physics of neutron-rich isotopes being unveiled at facilities such as the Facility for Rare Isotope Beams (FRIB) at Michigan State University. In the cosmological context, this physics is important for exploring lepton number constraints, and vetting beyond-standard-model possibilities with light element abundances, N_eff , the sum of neutrino masses, etc. In turn, these quantities are key targets for cosmic microwave background (CMB) Stage-4 experiments. Addressing this challenge requires expertise beyond the scope of any single research group or discipline. Progress demands a concerted, collaborative effort that bridges efforts in time-domain astronomy and cosmology, nuclear/particle theory - ranging from magnetohydrodynamics to quantum many-body theory - and neutrino experiments. The Aspen Center for Physics winter workshop is designed to unite experts across these domains, making explicit connections between the fundamental physics of neutrino flavor transformations with planning and interpreting observations in cosmology and transient science. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.3.

Building on the successes of PGU workshops in 2016 and 2018, PGU-3 aims to foster an interdisciplinary exchange among physicists, astro-cosmologists, and technologists. The workshop will explore the frontiers where quantum mechanics, particle physics, and gravitation converge, examining both foundational theory and emerging quantum-enabled technologies. Like its predecessors, the workshop will review cutting-edge developments, present new theoretical and experimental results, and discuss their broader scientific and technological impacts. Over the past century, physics, driven by the ideas of quantum theory, has undergone remarkable developments, offering new insights into our understanding of the Universe at both microscopic and macroscopic scales. PGU-3 welcomes leading invited speakers, contributed talks, and poster presentations. The workshop also aims to strengthen education and research in Vietnam and the Asia-Pacific region, while fostering collaboration across international institutions. Participants are encouraged to register and submit abstracts for contributed talks or posters via the workshop website. We look forward to a stimulating three-day program of plenary sessions, focused discussions, and informal networking opportunities in the vibrant city of Hanoi. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.4. Quantum analogues, Luxembourg --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29755 Starting: 2025-09-15 to 2025-09-16 Location: Luxembourg Additional Information: https://quantum-analogues.github.io/ Contact: upala.mukhopadhyay[AT]uni.lu What have water waves, Bose-Einstein condensates, semiconductor polaritons and fibre optics in common with black holes and the expanding universe? They are all quantum analogues. An analogue is a physical system that mimics the physics of another system. For example, water going down the drain establishes the analogue of the event horizon for water waves if the flow velocity exceeds the wave velocity. Quantum analogues mimic not only the classical physics of another system, but the quantum physics. For example, Bose-Einstein condensates may produce the quantum Hawking radiation of black holes. The Hawking radiation of real black holes is all but obscured by the Cosmic Microwave Background (and even more so by accretion radiation) but not so in black hole analogues, and neither is particle creation and the Gibbons-Hawking radiation of the expanding universe. Laboratory analogues have given us a good, hands-on understanding of how these quantum processes work, that are critical to the connection between quantum mechanics, thermodynamics and gravity. These ideas have a good chance of resolving the recent tensions in cosmology by predicting of how the quantum vacuum generates what is called dark energy (for want of a more enlightening term). Quantum analogues have also become a meeting place of different communities, from fluid mechanics to astronomy, where ideas are exchanged that would otherwise remain in their scholarly boundaries, and where young researchers are educated to be open-mind. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.5.

Giulio Rampa PhD Thesis Prize, Awardee of the 2025 Edition ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/07/07/giulio-rampa-phd-thesis-priz… Additional Information: http://www-2.unipv.it/dottorati/scienzeetecnologie/fisica/n/web_PhD/index.p… We are pleased to announce that the 2025 Giulio Rampa Thesis Prize for outstanding research in General Relativity will be presented to Dr. Thomas B. Mieling The Committee consisting of Profs. Lars Andersson, Mauro Carfora, Claudio Dappiaggi, Gerhard Huisken, Stefano Liberati, Luciano Rezzolla, Fulvio Ricci, and Mairi Sakellariadou prepared the following laudation: Dr. Mieling's Ph. D. thesis,"Gupta-Bleuler Quantization of the Electromagnetic Field in Curved Spacetimes with Applications to Gravitational Photon Interferometry",recognized by the Austrian Ministry of Sciences as one of the best PhD Theses of the year, offers a comprehensive and brilliant analysis of a new approach to the theory of gravitational photon interferometry that combines physical and geometrical insights. His work, marked by exceptional scientific originality, accounts for the quantum properties of the electromagnetic field while accurately describing the propagation of light in optical fibers in curved spacetimes. The work is a brilliant marriage of quantum field theory in curved spacetimes with classical gravitation, and it bears great relevance in current state-of-the-art experimental efforts by providing the theoretical foundation for understanding current proposals for experiments to measure the gravitationally induced phase shift in quantum states of light in optical fibers. Thomas Mieling is an outstanding scholar emerging as an excellent and active young scientist in gravitational theory, among the best early-career scientists of his generation, and we will look at his work as foundational in the field. The prize is sponsored by the University of Pavia, the Almo Collegio Borromeo, and the Italian Society for Relativity and Gravitational Physics (SIGRAV) to honor the memory of Giulio Rampa. It is given to a graduate student every two years for outstanding research in general relativity. The prize was established in 2011 and is endowed under the terms of a donation from Nadia and Giorgio Rampa. Each GRT prize carries a certificate and a net check for EUR 2,000. The award will be presented to Thomas Mieling at the 26th edition of the "Italian Society for General Relativity and Gravitation (SIGRAV) Conference" that will be held at the University of Milano-Bicocca (Milano), Italy, on 8-12 September 2025. This biennial conference is devoted to all aspects of gravitational physics. The Rampa Prize winner will present his work during a special conference session. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2. Piotr T.

The PhD project will be centred around data analysis for LISA in the presence of realistic noise. Many techniques developed for the gravitational wave data analysis rely on the assumption that the noise is stationary and Gaussian. However, in reality we are going to have noise artefacts in the data such as glitches, gaps, and spectral lines. The topic of PhD will include developing AI-based inference techniques that incorporate realistic noise to produce rapid low-latency parameter estimation for massive black hole binaries, which is crucial for multi-messenger astronomy. Moreover, the PhD student will work on the detection of transient signals and methods to distinguish different types of transients. The thesis will be carried out at the ARTEMIS lab at the Observatoire de la Cote d'Azur, located in Nice, France. The lab is involved in research dedicated to gravitational waves, with broad expertise ranging from experimental work to fundamental physics, astrophysics, and data analysis, for both ground-based (LVK) and space-based (LISA) detectors. The prospective student will become part of the LISA Consortium and Distributed Data Processing Centre (DDPC) and participate in its activities. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2.9.

Living Reviews in Relativity: "Cosmology using numerical relativity" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/06/24/living-reviews-in-relativity… Additional Information: https://link.springer.com/journal/41114 The open-access journal Living Reviews in Relativity has published a new review article on 23 June 2025: Josu C. Aurrekoetxea, Katy Clough and Eugene A. Lim. Cosmology using numerical relativity. Living Rev Relativ 28, 5 (2025). https://doi.org/10.1007/s41114-025-00058-z Abstract: This review is an up-to-date account of the use of numerical relativity to study dynamical, strong-gravity environments in a cosmological context. First, we provide a gentle introduction into the use of numerical relativity in solving cosmological spacetimes, aimed at both cosmologists and numerical relativists. Second, we survey the present body of work, focusing on general relativistic simulations, organised according to the cosmological history - from cosmogenesis, through the early hot Big Bang, to the late-time evolution of the universe. We discuss the present state-of-the-art, and suggest directions in which future work can be fruitfully pursued. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Quantum Reference Frames 2025, Okinawa, Japan --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29533 Starting: 2025-10-13 to 2025-10-17 Location: Okinawa, Japan Additional Information: https://www.oist.jp/conference/qrf-2025 Contact: qrf2025[AT]oist.jp Quantum reference frames are a universal tool for dealing with symmetries in quantum systems. They thus arise in seemingly disparate areas such as quantum gravity, gauge theories, quantum information theory, and the foundations of quantum theory. They are the tools for describing quantum systems "from the inside", and a core development is that they give rise to a novel quantum covariance of physical laws and properties. This workshop will bring together leading experts on quantum reference frames and the many related subjects in the first focused event in the new era of quantum frame covariance. Owing to their diverse range of applicability, a number of approaches to quantum reference frames have emerged. This event will reflect these diverse developments and aim to unify and streamline them. Our goal is to bring representatives from different approaches and disciplines in which quantum frames appear together to discuss and foster building an emergent community. The workshop will include contributed talks, discussions, a poster session, and some social activity. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.2. Extremal Black Holes and the Third Law of Black Hole Thermodynamics, Providence, RI USA --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29559 Starting: 2026-01-05 to 2026-01-09 Location: Providence, RI USA Additional Information: https://icerm.brown.edu/program/topical_workshop/tw-26-ebh Contact: steve.liebling[AT]liu.edu Applications are now open for an upcoming workshop, "Extremal Black Holes and the Third Law of Black Hole Thermodynamics" planned for January 5-9, 2026 at ICERM, Brown University, US. The aim of the workshop is to explore the implications and next steps of recent advances in understanding the dynamics and thermodynamics of near extremal black holes. By bringing together researchers in this area spanning the wide range of approaches, from rigorous mathematics, perturbation theory, and numerical methods, the workshop will focus on future directions. Extremal black holes are mathematical solutions of Einstein's equations describing stationary black holes with either maximal spin or maximal charge, and these black holes have special properties such as zero temperature. Recent studies have found certain surprising aspects of their dynamics including scalar hair and an avenue for their formation from subextremal configurations that violate the third law of black hole thermodynamics. These results raise a number of questions including the stability and critical behavior of such solutions that may be addressed via other research avenues.

Evolved LISA Consortium: information and sign-up ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29573 Additional Information: https://www.lisamission.org/team/ After the adoption of the LISA mission by ESA in January 2024 the LISA Consortium has gone through a transition period in which a Consortium Constituent Council prepared the evolution of the consortium to match the organisation and data policy of the mission. The consortium does not directly provide components to the mission but is a scientific collaboration working together to maximize the scientific return of LISA, in particular using the open LISA data. The consortium is ex officio represented in the ESA/NASA LISA Science Team. With this email we want to inform you about this transition and the options to join the LISA Consortium . In the evolved LISA Consortium there are two types of members: core members who commit to deliverables for the consortium (or the LISA mission - those working on hardware, DDPC, NSGS, etc.) and community members who want to be involved and informed. The work of the consortium is organised in working groups and the consortium is overseen by a representative council and led by a management team that includes a spokesperson and the science team representative. The Consortium registration link and more information about the new structure and the transition can be found on the LISA Consortium website. https://www.lisamission.org/team/ We have been transitioning the members of the existing consortium and now welcome sign-up from the rest of the community. Prior to signing up as a core member, please make sure you understand the commitments and benefits of core members (e.g. no preferred data access, commitment to spend time on consortium projects, and yearly review of activities). Additionally, please read the Membership Quick Guide linked from the registration page (and attached here) in all its parts, where you can find an explanation of all the entries of the form and subsequent steps. Note that becoming a consortium member does not happen upon approval of your sign-up: depending on your type of membership, more steps may be required. In particular, users become core members only when their pledge is submitted and approved, not when they sign up. We look forward to welcoming colleagues to the new LISA Consortium! Best regards, Jonathan Gair and Deirdre Shoemaker (On behalf of the LISA Consortium transition council) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.5. The Thirtieth Release of the Einstein Toolkit ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/05/29/the-thirtieth-release-of-the… Additional Information: https://einsteintoolkit.org/about/releases/ET_2025_05_announcement.html We are pleased to announce the thirtieth release (code name "Martin D. Kruskal") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include: One new thorn has been added: * CCE_Export -- This thorn provides output support for data to be used in the "SpECTRE Cauchy-characteristic evolution" code to extract waveforms at infinity. Updated thorns: * CarpetX -- Further updates and new functionality. * Derivs -- Add support for 6th and 8th order accurate finite differencing. * FLRWSolver -- This thorn provides cosmological initial conditions based on a Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime, either with or without small perturbations. Along with one new gallery example: * Black-hole hair in axi-dilaton gravity -- Evolving a single black hole under modified axi-dilation gravity. In addition, bug fixes accumulated since the previous release have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems. It builds on numerous software efforts in the numerical relativity community, including codes to compute initial data parameters, the spacetime evolution codes Baikal, lean_public, and McLachlan, analysis codes to compute horizon characteristics and gravitational waves, the Carpet AMR infrastructure, and the relativistic (magneto)hydrodynamics codes GRHayLHD, GRHayLHDX, GRHydro, and IllinoisGRMHD. Data analysis and post-processing are handled by the kuibit library. The Einstein Toolkit also contains a 1D self-force code. For parts of the toolkit, the Cactus Framework is used as the underlying computational infrastructure, providing large-scale parallelization, general computational components, and a model for collaborative, portable code development. The Einstein Toolkit uses a distributed software model. Its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers ensure quality control for modules included in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve staff and faculty from five different institutions and host weekly meetings that are open to anyone. Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought-out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers. The Einstein Toolkit is primarily supported by NSF 2004157/2004044/2004311/2004879/2003893/2114582/2227105 (Enabling fundamental research in the era of multi-messenger astrophysics). The "Martin D.

First International Latin American Conference on Gravitational Waves, Sao Jose' dos Campos, Brazil --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29457 Starting: 2025-09-15 to 2025-09-19 Location: Sao Jose' dos Campos, Brazil Additional Information: https://agenda.infn.it/event/45592/overview Contact: lagwc.feg[AT]unesp.br A decade ago, science witnessed an extraordinary milestone: the first direct detection of gravitational waves, predicted by Albert Einstein in his Theory of General Relativity in 1915. These ripples in spacetime, generated by extreme cosmic events such as black hole mergers, remained merely a theoretical prediction until September 14, 2015, when the LIGO (Laser Interferometer Gravitational-Wave Observatory) experiment captured this historic signal. This achievement revolutionized astrophysics and earned the 2017 Nobel Prize in Physics for Rainer Weiss, Barry C. Barish, and Kip S. Thorne, recognizing their essential contributions to the design and implementation of LIGO, as well as the data analysis that confirmed the phenomenon. The First International Latin American Conference on Gravitational Waves celebrates this milestone by bringing together researchers from across Latin America to discuss advancements in detection, theory, and instrumentation in the field of gravitational waves. Moreover, the event serves as a unique opportunity to unify and strengthen the Latin American scientific community, fostering institutional partnerships and collaborations that solidify the region's presence in this cutting-edge field of science. The conference will include lectures by world-renowned experts, seminars, poster sections, contributed talks, and panel discussions, including a special lecture by Barry Barish, Nobel Laureate. Where? Instituto Nacional de Pesquisas Espaciais (INPE), Brazil, Sao Jose' dos Campos, SP When?

The organizers: Chiara Caprini, Simona Procacci, Alberto Roper Pol, Philipp Schicho, and Jorinde van de Vis ---------------------- Abstract: As the detection of a stochastic gravitational wave (GW) background from the early universe becomes increasingly plausible, signals from hypothetical first-order phase transitions are attracting growing interest. Predicting these signals often requires microphysical inputs to solve hydrodynamics, along with various assumptions on distinctive scales and their separation to enable concrete evaluations. This workshop aims to unite researchers from both microphysical and macrophysical communities to collaboratively address theoretical shortcomings and refine current GW spectral templates across different regimes. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.5.

IMS workshop: Mathematical Methods for the General Relativistic Two-body Problem, Singapore --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/04/14/ims-workshop-mathematical-me… Starting: 2025-08-11 to 2025-08-15 Location: Singapore Additional Information: https://ims.nus.edu.sg/events/generalrelativistictwobodyproblem/ Contact: nusgwgroup[AT]gmail.com We are pleased to announce a workshop titled "Mathematical Methods for the General Relativistic Two-body Problem", which is to be held from 11 to 15 August 2025 at the Institute for Mathematical Sciences (IMS) at the National University of Singapore (NUS). Applications for this workshop are now open on the event website [ https://ims.nus.edu.sg/events/generalrelativistictwobodyproblem/ ] By the mid-2030s, we will be able to observe astrophysical gravitational-wave sources across multiple frequency bands, which will greatly advance our understanding of the physical Universe. Asymmetric binary systems will be a main source of gravitational waves, particularly in the multi-band era. The best way to model asymmetric binaries is to expand Einstein's field equations about the small mass ratio of the system. The small mass ratio of these systems leads to unique mathematical challenges in the modelling and statistical analysis of their gravitational-wave signals, as well as their broader characterisation in the active astrophysical environments where they typically form. The aim of this week-long workshop is to provide a forum for exchanging ideas and updates on the significant challenges associated with modelling and interpreting gravitational-wave signals from asymmetric binary system as a source for LISA. The workshop will be structured along the three main themes of theory, computation and science, and each theme will be addressed through a combination of invited talks and discussion sessions. The participants will consist of experts across these areas. To facilitate productive interaction, the workshop will be capped at 40 participants, and will allocate plenty of time for discussion and collaboration while limiting the number of talks each day. With support from the IMS, we might be able to support a limited numbers of early-career researchers in participating in this event. Please note that accommodation is the only available support. Applications will be accepted until all workshop openings are filled, but we recommend applying before 16 May 2025 for full consideration, particularly those who would like to be considered for the financial support from IMS. Please contact nusgwgroup[AT]gmail.com for any queries. We look forward to welcoming you this summer in Singapore!

SN2025gw: First IGWN Symposium on Core Collapse Supernova Gravitational Wave Theory and Detection, Warsaw, Poland --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/04/24/sn2025gw-first-igwn-symposiu… Starting: 2025-07-21 to 2025-07-25 Location: Warsaw, Poland Additional Information: https://indico2.fuw.edu.pl/event/17/ Contact: sn2025gw[AT]fuw.edu.pl The LIGO-Virgo-KAGRA Collaboration invites the core-collapse supernova (CCSN) astronomy and astrophysics community for a 5-day Symposium on July 21-25, 2025, at the University of Warsaw, Poland. CCSNe are among the most violent explosions known to occur in the Universe, and the next Galactic or near extra-Galactic exploding massive star will be one of the most interesting, and most important, astronomical events of the century. This Symposium aims to bring CCSN experts together to address how to maximize the scientific potential of the first detection of core collapse supernova gravitational waves (GWs). The Symposium hopes to bring together GW astronomers and CCSN modelers, as well as neutrino and nuclear theorists, neutrino astronomers, and astronomers across the electromagnetic spectrum. The sensitivity of GW detectors and progress on CCSN modeling are unprecedented, and we expect them to further advance in the coming years. A joint effort across communities has great potential to fully utilize these advances for CCSN GW discovery. Each day, we will host (before lunch) a set of lectures on one of the key topics listed below, to establish a common understanding and a common language. Moreover, each day (after lunch) will also include invited and contributed talks, as well as discussion. The focus topics of the Symposium are: Day 1: CCSN Theory Day 2: CCSN Gravitational Wave Detection and Parameter Estimation Day 3: CCSN Neutrino Detection Day 4: CCSNe across the Electromagnetic Spectrum Day 5: CCSNe over the Next Ten Years The proceedings of the Symposium will be published in a special issue of Classical and Quantum Gravity. We hope the proceedings will serve as a reference for students, postdocs, and faculty in, or entering, the field, serve to capture the current state of core collapse supernova gravitational wave astronomy and astrophysics, outline lessons learned, and provide recommendations for future development. Everyone who wishes to advance the field of CCSN GW science is welcome! +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.11.

Recent Progress on Black Hole Spin Measurements Across the EM and GW Spectrum, Winston-Salem, NC, USA --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29318 Starting: 2025-09-25 to 2025-09-26 Location: Winston-Salem, NC, USA Additional Information: https://cardenas.sites.wfu.edu/spinworkshop/ Contact: alejandro[AT]wfu.edu This two-day workshop will bring together experts in gravitational and electromagnetic wave astrophysics to address the shared theoretical challenges of modeling and measuring black hole spins. The event will feature a mix of talks and discussions throughout the workshop. Invited speakers will deliver two 30-minute talks: the first will focus on the current theoretical understanding in their field, while the second will highlight the outstanding uncertainties and open questions. These presentations will provide a strong foundation for integrating diverse theoretical perspectives and fostering a shared understanding of black hole spin measurements across different techniques, including X-rays, gravitational waves, and millimetric black hole imaging. Discussions will be interspersed throughout the workshop to promote collaboration and bridge gaps between these theoretical communities. Key topics will include the development of theoretical models for inferring black hole spin from astrophysical observations, as well as the exploration of observational selection effects that influence spin distributions in black hole populations, such as low and high-mass X-ray binaries (LMXBs and HMXBs) and binary black holes (BBHs). The workshop will also focus on strategies to reconcile theoretical models with observational results. The goal is to establish a unified framework for understanding black hole spin and advancing our knowledge of black hole formation and evolution through integrated theoretical approaches. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.7. Spacetime Matters Conference, Utrecht, The Netherlands --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29320 Starting: 2025-09-01 to 2025-09-02 Location: Utrecht, The Netherlands Additional Information: https://www.uu.nl/en/research/utrecht-philosophy-of-astronomy-cosmology/eve… Contact: a.e.ferreirodeguiar[AT]uu.nl The COSMO-MASTER team and UPAC group are organising a two-day conference on the conceptual dichotomy between spacetime and matter, taking place in Utrecht (NL) on the 1st and 2nd of September 2025. This conference will be directly followed by the Utrecht Philosophy of Astronomy and Cosmology (UPAC) conference (3-5 Sept). We welcome physicists, philosophers, and anyone else who may be interested, to submit an abstract or register as a participant (registration opening in the spring). In Newtonian physics, there is a strict conceptual dichotomy between space(time) and matter, in the sense that all ingredients of a Newtonian ontology are either purely space(time), (the "container"), or purely matter (that what is "contained"). Such a mutually exclusive categorisation starts to blur once we consider the metric in general relativity, an entity that is typically introduced as representing spacetime, but which also exhibits various paradigmatic features of being matter, such as being dynamical, reacting when being acted upon, and (controversially) carrying energy. Various entities in modern astronomy and cosmology (e.g. dark matter, dark energy, black holes, inflation) similarly resist the old Newtonian mold. The concepts of spacetime and matter further degrade once entering the regime of quantum gravity. Understanding these conceptual categories affects both model building in physics, as well as various philosophical debates, e.g. substantivalism versus relationalism about spacetime. This conference scrutinises the tenability of a rigid dichotomy between spacetime and matter, and the consequences of a breakdown of these Newtonian goggles. Possible topics include but are not limited to: gravitational energy black holes, dark matter, dark energy, inflation and the spacetime-matter split the relationship between spacetime functionalism and matter (functionalism) conventionalism the spacetime-matter split in quantum gravity supersymmetry and superspace the spacetime-matter split and the substantivalism-relationalism debate the spacetime-matter split and the debate between the geometrical and dynamical account of spacetime the spacetime-matter split and scientific realism spin-2 gravity vs general relativity the container metaphor (hybrid) model building in astronomy and cosmology Confirmed keynote speakers: Domenico Giulini (Hannover) James Read (Oxford) Kian Salimkhani (Nijmegen) Proposals for contributed presentations should be submitted to cosmo-master(a)uu.nl by the 25th of April 2025 as a pdf, and should consist of a title, an extended abstract of 300-500 words (excluding bibliography), and a short one-paragraph narrative CV that describes your research profile and includes your current affiliation (if any).

Living Reviews in Relativity: "Gravitational-wave tests of general relativity with ground-based detectors and pulsar-timing arrays" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29359 Additional Information: https://link.springer.com/journal/41114 The open-access journal Living Reviews in Relativity has recently published an updated review article on 03 March 2025: Nicolas Yunes, Xavier Siemens and Kent Yagi. Gravitational-wave tests of general relativity with ground-based detectors and pulsar-timing arrays. Living Rev Relativ 28, 3 (2025). https://doi.org/10.1007/s41114-024-00054-9 This article is a revised version of https://doi.org/10.12942/lrr-2013-9 . Change details We have implemented a great deal of changes to generate this new updated version. These have led to a document that is about twice the size of the original one with about 3 times the number of references (increased from 475 to 1220). In particular, we have added a new author, Prof. Kent Yagi from U. of Virginia, who was instrumental in the update process. We have also added content related to the plethora of tests of GR that have been performed with the Advanced LIGO and Virgo observations. We have also created a completely new Sect. 5 on tests of GR with PTAs, since the latter have now detected a stochastic background. In the process of updating the document, we also corrected several typos in equations that we found since the time we created the original document. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Windows to probe the universe such as the cosmic microwave background (CMB) and large-scale galaxy surveys (LSS) have become precision science, and new windows such as 21cm redshift surveys with radio telescopes are opening up. In light of these advances in observational cosmology, the challenges on theoretical cosmology have grown rapidly. The standard first-order linear perturbation theory, which is the current main tool in the literature, has been pushed to its limits, and improved approaches are needed in interpreting precision measurements in observational cosmology. Beyond linear order in perturbations, fluctuations on any particular physical scale obtain contributions from other Fourier modes, which are independent in the linear regime. Of particular interest among these nonlinear effects to cosmological observations are so called "back-reaction effects, by which both short wavelength non-linear fluctuations affect the larger scale modes and hence the background evolution in large-scale structure of the Universe. There are also back-reaction effects of long wavelength linear modes on the modes which are currently measured in observations. The aim of this workshop is to bring together experts working on various aspects of back-reaction problems, with particular emphasis on computing the effects on measurable quantities which are based on light cone averages.

Is it fundamental or emergent? This question lies at the foundation of contemporary physics and provides a key to unlocking some of its most challenging open problems, from quantum gravity to cosmology. The quest to understand time extends beyond the realm of physics, providing a privileged standpoint to address questions in diverse fields such as philosophy, mathematics, and computer science. In this conference, we explore the nature of time from many different perspectives. This is the occasion to honor Perimeter's "Master of Time," Lee Smolin, and to celebrate his seminal scientific contributions. Lee Smolin is a founding faculty member of Perimeter Institute and a primary inspiration behind its spirit and design. This is an opportunity to journey back in time to the origins of some of the groundbreaking initiatives that Lee helped develop, and to look forward to future developments inspired by his achievements. The conference focuses on time but also on the foundations of quantum mechanics and the quest for quantum gravity, particularly Loop Quantum Gravity, of which Lee Smolin is a co-creator. In the spirit of Lee Smolin, the conference celebrates the interdisciplinary nature of the journey toward quantum gravity, with contributions from physics, mathematics, computer science, and philosophy.

Numerical models of extreme stellar explosions: bridging the gap between the central engine and the emission region, Special Session at EAS 2025, Cork, Ireland --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2025/02/17/numerical-models-of-extreme-… Starting: 2025-06-23 to 2025-06-27 Location: Cork, Ireland Additional Information: https://eas.unige.ch/EAS_meeting/session.jsp?id=SS31 Contact: matteo.bugli[AT]iap.fr We are glad to announce a Special Session (SS31) titled "Numerical models of extreme stellar explosions: bridging the gap between the central engine and the emission region" at the upcoming EAS 2025 Annual Meeting. The meeting will be held on June 23-27 in Cork, Ireland, with SS31's exact date to be announced soon. This special session aims at bringing together experts in the modeling of all the different phases that characterize extreme stellar explosions, from their initial onset to the emission of the electromagnetic transient. The main goal is to foster discussions and collaborations that will help the community to develop a deeper understanding of the fundamental physical processes at work during these events and trace the path to connect observed GRBs to their stellar progenitors. We will focus on three major topics related to the modeling of extreme stellar explosions: - The formation and dynamics of the central engine (i.e. extreme core-collapse supernovae, collapsar, binary neutron stars and neutron star-black hole mergers) - The relativistic jet (launch mechanism, propagation through the stellar progenitor or the merger ejecta, interaction with the surrounding medium) - The multi-wavelength electromagnetic and multi-messenger emission (including energy dissipation mechanisms and particle acceleration processes, GW, and neutrinos) If you are interested in participating, you are kindly invited to submit an abstract by March 3. We look forward to seeing you in Cork! The organizing committee of SS31 (M. Bugli, M. Bernardini, F. Daigne, M. Obergaulinger, E. O'Connor, B.

Event Description: Today, cosmology and astrophysics are experiencing a dilemma: on one side, we have a very successful model, the LambdaCDM model, able to adjust to almost all observations. On the other hand, such a model requires 96% of stuff about whose nature we have yet no certain knowledge: 26% of dark matter and 70% of dark energy, with only 4% left for the known matter, mostly in the form of hydrogen and helium nuclei. While dark matter seems to be necessary to explain the formation and the dynamics of galaxies and of larger structures, such as galaxy clusters and super clusters, dark energy is required to explain why our universe is in a state of accelerated expansion. The school aims at providing master's and doctoral students and young post doctoral researchers with a perspective on the most important proposals on the nature of the dark components of the universe, not only from the theoretical point of view, but also from the experimental and observational one.

Applications of machine learning in gravitational-wave research with current interferometric detectors. Living Rev Relativ 28, 2 (2025). https://doi.org/10.1007/s41114-024-00055-8 Abstract: This article provides an overview of the current state of machine learning in gravitational-wave research with interferometric detectors. Such applications are often still in their early days, but have reached sufficient popularity to warrant an assessment of their impact across various domains, including detector studies, noise and signal simulations, and the detection and interpretation of astrophysical signals. In detector studies, machine learning could be useful to optimize instruments like LIGO, Virgo, KAGRA, and future detectors. Algorithms could predict and help in mitigating environmental disturbances in real time, ensuring detectors operate at peak performance. Furthermore, machine-learning tools for characterizing and cleaning data after it is taken have already become crucial tools for achieving the best sensitivity of the LIGO-Virgo-KAGRA network. In data analysis, machine learning has already been applied as an alternative to traditional methods for signal detection, source localization, noise reduction, and parameter estimation. For some signal types, it can already yield improved efficiency and robustness, though in many other areas traditional methods remain dominant. As the field evolves, the role of machine learning in advancing gravitational-wave research is expected to become increasingly prominent. This report highlights recent advancements, challenges, and perspectives for the current detector generation, with a brief outlook to the next generation of gravitational-wave detectors. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2.

Part II of this workshop will be held in Summer 2026 at the National University of Singapore (NUS). Applications for Part I are now open on the event website. When compact objects such as neutron stars or stellar-mass black holes venture into the vicinity of giant black holes, they can form highly asymmetric and strongly relativistic binary systems known as extreme-mass-ratio inspirals (EMRIs). EMRIs are some of the most promising gravitational-wave sources that the upcoming space mission LISA might observe, but also some of the most difficult to model, detect and characterise. The aim of this workshop is to bring together experts in EMRI science and LISA data analysis, to assess the state of the art in the field and to further develop plans for the optimal extraction of science from such sources. The workshop will focus mainly on data analysis techniques for EMRI search and inference in the broader context of the LISA global fit, but will naturally extend to adjacent topics such as the construction of accurate and efficient waveform templates, and the impact of astrophysical environments on EMRI modelling and interpretation. To facilitate productive interaction, the workshop will be capped at 40 participants, and will allocate plenty of time for discussion and collaboration while limiting the number of talks each day. Applications will be accepted until all workshop openings are filled, but we recommend applying before 28 Feb 2025 for full consideration. We look forward to seeing you in Paris next year!

The upcoming/proposed GW observatories like SKA, LIGO-India, LISA, Taiji/TianQin, ET, CE, and LILA are expected to address some of the most pressing challenges in modern cosmology, such as the Hubble tension and the nature of inflation in the early Universe while providing ultra-sensitive tests for Einstein's universe. The workshop APCTP-GW2025 aims to bring together researchers from the Asia Pacific region who are working on various aspects of the rapidly advancing field of GW astronomy. Set in the beautiful backdrop of Taipei in the spring, participants will not only engage in discussions but also enjoy the excellent weather, vibrant culture, and authentic traditional cuisine. The workshop will be held at the Institute of Physics, Academia Sinica in Taipei, Taiwan from April 20 to April 25, 2025. Registration is free, but limited slots are available. Contributed talks and posters are welcome. Deadline of registration and submission of abstracts: 1st March 2025.

In particular, our understanding of space-time structure in quantum field theory might be in for an overhaul. Twistor theory, trace dynamics, and the number system known as octonions, will possibly play an important role in this improved understanding of space-time. Octonions have also emerged significantly in recent years in the investigation of elementary particles, the standard model, and its unification with gravitation. Perhaps the foundational underpinnings of quantum gravity, as well as of particle physics, need to be examined afresh. Do we need dark matter, or a modified law of gravitation? Does the standard model of cosmology need a revision? The present lecture series presents ongoing research from eminent physicists and mathematicians working in these fields. Each session will be two hours long, with one hour for the talk, followed by an hour long question-answer session. Hosts: Tejinder P.

New textbook: "Primordial Black Holes" ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29077 Additional Information: https://link.springer.com/book/9789819788866 Dear Colleagues, We would like to announce the new textboook: "Primordial Black Holes" Published by Springer Editors: Christian Byrnes, Gabriele Franciolini, Tomohiro Harada, Paolo Pani, Misao Sasaki Details of the book are available at https://link.springer.com/book/9789819788866 Primordial black holes (PBHs) were proposed more than 50 years ago as black holes possibly formed across a vast mass range in the early universe. They represent a unique probe to access the primordial universe and cosmological inflation. Furthermore, in certain mass ranges, they could comprise the entirety of the dark matter, seed supermassive black holes at high redshift, be responsible for some gravitational-wave events detected so far, and be novel gravitational-wave sources detectable with future instruments. However, detecting PBHs has proved to be extremely challenging and extensive research focused on setting a variety of constraints on the fraction of dark matter composed by these objects. This book highlights an up-to-date, comprehensive overview on this subject, including pedagogical details on the PBH formation scenarios, cosmological evolution, astrophysical implications, connections with gravitational-wave astronomy, and critical discussion of the latest and future constraints. At variance with all existing reviews on this subject, this book addresses graduate students and researchers not necessarily familiar with all areas of the topic, providing details on important key results rather than collecting and reviewing the latest literature. The topic is naturally interdisciplinary and connects areas as diverse as cosmology, particle physics, gravitational-wave astronomy, and numerical simulations. To reflect this diversity, the book includes 25 contributions from key researchers working in these different areas. It provides a unique reference both to approach the topic for the first time and to learn a specific specialized sub-area. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2.

(For the LISA Cosmology Working Group) Primordial black holes and their gravitational-wave signatures. Living Rev Relativ 28, 1 (2025). https://doi.org/10.1007/s41114-024-00053-w Abstract: In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain both some of the signals from binary black hole mergers observed in gravitational-wave detectors and an important component of the dark matter in the Universe. Significant progress has been achieved both on the theory side and from the point of view of observations, including new models and more accurate calculations of PBH formation, evolution, clustering, merger rates, as well as new astrophysical and cosmological probes. In this work, we review, analyze and combine the latest developments in order to perform end-to-end calculations of the various gravitational-wave signatures of PBHs. Different ways to distinguish PBHs from stellar black holes are emphasized. Finally, we discuss their detectability with LISA, the first planned gravitational-wave observatory in space. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.3.

Magnetic Fields around Compact Objects, Waterloo, Canada --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29002 Starting: 2025-03-26 to 2025-03-28 Location: Waterloo, Canada Additional Information: https://events.perimeterinstitute.ca/event/743/ Contact: lcombi[AT]perimeterinstitute.ca In the vicinity of neutron stars and black holes, where spacetime is strongly curved, magnetic fields can power many of the violent phenomena that we observe across the entire electromagnetic spectrum, from accretion and jet launching, to magnetar flares and pulsar emission. In the last decades, our theoretical understanding of the role of magnetic fields in these extreme environments has greatly improved through numerical simulations of magnetohydrodynamical fluids and charged kinetic particles; however, many open and important questions remain. Our observational capabilities and computational resources will keep growing dramatically in the next few years, allowing us to explore high-energy astrophysics in unprecedented regimes. Improving our knowledge of how magnetic fields, matter, and gravity interact with each other is a crucial piece in the new era of multimessenger astrophysics. This workshop will gather experts from a wide range of disciplines within physics and astrophysics to present state-of-the-art advances in theoretical models of magnetic fields and high-energy plasma in different contexts, from neutron star mergers to supermassive black holes, and from micro scales to macro scales.

Registration is now open. --------------------------- The high precision afforded by gravitational waves and black hole imaging observations have begun to open up the opportunity to test the black hole paradigm. As observations continue to improve, the need to better understand theoretical models of black hole mimicking ultra compact objects is becoming increasingly urgent. This workshop aims to bridge the gap by bringing together the three key communities working on complementary aspects of the problem - gravitational wave observations, black hole imaging, and well motivated theoretical modeling. With a series of talks, reviews, updates, and discussions, this workshop aims to connect theoretical developments with current and future observations, stimulate discussions across disciplines, identify open problems, and brainstorm a roadmap to map the most productive path forward. --------------------------- Speakers include: Cosimo Bambi, Ramy Brustein, Vitor Cardoso, Andrew Chael, Ulf Danielsson, Mariafelicia de Laurentis, Anuradha Gupta, Pierre Heidmann, Steven Liebling, Alex Lupsasca, Andrea Maselli, Elisa Maggio, Samir Mathur, Lia Medeiros, Alex Nielsen, Hector Olivares, Paolo Pani, Frans Pretorius. Registration is free, but required for in-person participation in the workshop. Live streaming and recording of all talks will be freely available and require no registration. The registration window will remain open until we reach maximum capacity. A limited number of slots are available for flash talks, and we encourage graduate students to take advantage of this opportunity by submitting a title and abstract for consideration.

The Twenty-Ninth Release of the Einstein Toolkit ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=29014 Additional Information: http://einsteintoolkit.org/about/releases/ET_2024_11_announcement.html We are pleased to announce the twenty-ninth release (code name "Annie Jump Cannon") of the Einstein Toolkit, an open-source, community-developed software infrastructure for relativistic astrophysics. The major changes in this release include: One new thorn has been added: * TOVola -- solves the Tolman-Oppenheimer-Volkov equations for simple polytropes, piecewise polytropes, and tabulated equations of state. Updated thorns: * CarpetX -- many updates and new functionality * GRHayL -- support WENO5 reconstruction In addition, bug fixes accumulated since the previous release have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems. It builds on numerous software efforts in the numerical relativity community, including codes to compute initial data parameters, the spacetime evolution codes Baikal, lean_public, and McLachlan, analysis codes to compute horizon characteristics and gravitational waves, the Carpet AMR infrastructure, and the relativistic (magneto)hydrodynamics codes GRHayLHD, GRHayLHDX, GRHydro, and IllinoisGRMHD. Data analysis and post-processing are handled by the kuibit library. The Einstein Toolkit also contains a 1D self-force code. For parts of the toolkit, the Cactus Framework is used as the underlying computational infrastructure, providing large-scale parallelization, general computational components, and a model for collaborative, portable code development. The Einstein Toolkit uses a distributed software model. Its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers ensure quality control for modules included in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve staff and faculty from five different institutions and host weekly meetings that are open to anyone. Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought-out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers. The Einstein Toolkit is primarily supported by NSF 2004157 / 2004044 / 2004311 / 2004879 / 2003893 / 2114582 / 2227105 (Enabling fundamental research in the era of multi-messenger astrophysics).
