Conferences ============================================== 1.1. CosmoVerse@Lisob, Lisbon, Portugal --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/01/02/cosmoverselisob/ Starting: 2023-05-30 to 2023-06-01 Location: Lisbon, Portugal Additional Information: https://indico.unina.it/event/70/ Contact: jackson.said[AT]um.edu.mt CosmoVerse@Lisbon is the first annual conference in a series of conferences which aim to establish a synergy between the different research areas in cosmology, and foster a sustainable network based on interdisciplinary research in order to confront the growing challenges of tensions in cosmological survey data. This conference is organized within the Cost action initiative CA21136 - Addressing observational tensions in cosmology with systematics and fundamental physics (CosmoVerse). Our understanding of the Universe is at a turning point with the predictions of the standard cosmological model and the observations from different surveys are showing tensions in several key areas. The disagreement is expressed in the value of cosmic expansion as well as in the growth of large-scale structure in the Universe. New cosmological surveys, many of which are European, may expose tension in additional areas of the concordance model. The question of cosmological tensions can be confronted in a number of ways. Firstly, survey data needs to be further analysed for potential systematic uncertainties or biases. Secondly, there have been numerous advances in approaches to data analysis and statistics, some of which provide less dependence on cosmological models to make cosmological parameter estimates. Lastly, there are a plethora of new proposals from fundamental physics which range from novel neutrino physics to dark energy proposals (and others) which may contribute to a solution to the cosmological tensions problem. These represent the three research themes through which cosmological tensions will either be alleviated or resolved. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.2.

Quantum Effects in Gravitational Fields, Leipzig, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/01/04/quantum-effects-in-gravitati… Starting: 2023-08-28 to 2023-09-01 Location: Leipzig, Germany Additional Information: https://indico.tpi.uni-jena.de/e/qegf Contact: qegf[AT]uni-leipzig.de The combination of quantum and gravitational physics led decades ago to the prediction of quantum radiation by black holes and the production of quantum particles in expanding universes. In recent years there has been a resurgence of interest, arising from both a theoretical and an experimental perspective. On the theoretical side, there are significant new findings regarding quantum effects in the inside of black holes or the interconnections between quantum entanglement, gravity, and holography. On the experimental side, there have been advances on observational signatures of quantum effects in gravitational fields, motivated partly by impressive advances in technology. During August 28-September 1, 2023, we will hold an in-person conference at Leipzig University, Germany, to present and discuss recent developments in the field. Confirmed plenary speakers are: Eanna E. Flanagan (Cornell, U.S.A.) Stefan Floerchinger (Heidelberg and Jena, Germany) Christian Gerard (Orsay, France) Veronika E. Hubeny (UC Davis, U.S.A.) Harvey S. Reall (Cambridge, U.K.) Jeff Steinhauer (Technion, Israel) Robert M. Wald (Chicago, U.S.A.) Elizabeth Winstanley (Sheffield, U.K.) Noa Zilberman (Technion, Israel) We also welcome contributed talks from scientists working on this area.

Organizers: Marc Casals Stefan Hollands Rainer Verch Jochen Zahn Funded via the Jena-Leipzig DFG Research Training Group 2522. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.5. Gravitational-wave populations: what's next?, Milan, Italy --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2023/01/12/gravitational-wave-populatio… Starting: 2023-07-10 to 2023-07-14 Location: Milan, Italy Additional Information: https://sites.google.com/unimib.it/gwpopnext Contact: davide.gerosa[AT]unimib.it It is a pleasure to announce the workshop "Gravitational-wave populations: what's next?" which we are currently organizing for next summer: https://sites.google.com/unimib.it/gwpopnext As the catalog of detected gravitational-wave events grows from O(10) to O(100) sources (but think millions in a few decades!), such increasingly detailed information is allowing us to dig deeper into the (astro)physics of compact objects. At the same time, new and more data require appropriately powerful statistical tools to be fully exploited. This highly interactive workshop (fewer talks, more working together!) will be the opportunity to share recent progress, identify what new steps are now needed, and hopefully set the stage for substantial progress in the field. The workshop will take place on July 10-14, 2023 at the University of Milano-Bicocca, which is located near the city center of Milan, Italy. Milan is a beautiful, international city in the north of Italy and is served by three major airports with worldwide connections. The city is home to art, history, and great food; nearby excursions will take you to the Italian lakes and the stunning Alps. While we are unable to provide travel support, the workshop will have no registration fee. The workshop will be in person without remote options. Interested participants should register on the conference website by March 1st, 2023. Depending on the number of people registering, participants might need to be selected. We will be in touch soon after the registration deadline, so please do not make travel plans until you hear back from us. When registering please indicate which of the discussion session(s) you would like to contribute to. Early career scientists will have the opportunity to give flash talks highlighting their science.

The aim of this workshop continues to be to gather researchers from around the world who work in topics related to QFTCS, both in its mathematical conceptualization, and its applications in cosmology and astrophysics. The main research lines we aim to cover in the workshop include: QFT in the early universe and black holes, semiclassical Einstein equations and the backreaction problem, relativistic quantum information, and mathematical foundations of QFTCS. Additionally, for this second edition, we plan to include topics related to quantum gravity: namely, how QFTCS fits within the different approaches toward quantum gravity. We strongly encourage the participation of researchers from the field of quantum gravity with an interest in phenomenology and QFTCS. Plenary speakers: - Marc Casals - Renate Loll - Eduardo Martin-Martinez - Beatrice Bonga (special colloquium) The contributions are expected to last 15 minutes + questions. However, special requests for extended talks could be considered. We encourage the participation of researchers in the early stages of their career (PhD students and postdoc researchers). There is a registration fee of 150 EUR. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.7. Werner Israel Memorial Symposium, Victoria, BC, Canada (hybrid) --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=25976 Starting: 2023-05-18 to 2023-05-19 Location: Victoria, BC, Canada Additional Information: https://meetings.triumf.ca/event/332/ Contact: phys_wims[AT]uvic.ca This symposium will celebrate the scientific career and legacy of Werner Israel, one of the leading figures in the development of our modern understanding of general relativity and black holes. Among many impactful contributions, Werner proved the foundational no-hair theorems for the exterior of static black holes, and later the phenomenon of mass inflation for the interior of rotating black holes (with his student E. Poisson); he devised the Israel junction conditions for extended gravitating sources, and developed the causal Muller-Israel-Stewart theory for relativistic thermodynamics and hydrodynamics. The symposium will be held in hybrid format on the campus of the University of Victoria, in Victoria BC, and will run over two full days May 18-19, 2023. The evening of May 18th will include a reception followed by a conference dinner. In celebrating Werner's remarkable scientific legacy, the symposium aims to bring together researchers with interests aligned with various themes of Werner's research, both historical and modern. To this end, the focus of the meeting will be on properties of black holes and relativistic matter. To register and for further information, please visit the conference website: https://meetings.triumf.ca/event/332/ We look forward to seeing you in Victoria.

New horizons for (no-)horizon physics: from gauge to gravity and back II, Florence, Italy --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=25979 Starting: 2023-04-17 to 2023-04-21 Location: Florence, Italy Additional Information: https://www.ggi.infn.it/showevent.pl?id=455 Contact: paolo.pani[AT]uniroma1.it To be held in person at the INFN Galileo Galilei Institute (GGI) on 17-21 April, 2023. Motivated by the recent breakthroughs in gravitational-wave (GW) astronomy and in the imaging of black holes (BHs), the last few years have witnessed a growing interest in exploring the phenomenology of BHs, compact objects, and horizonless micro-states which emerge in the 'fuzzball' proposal in string theory. Semi-analytical, fully numerical techniques and, more recently, exact methods from gauge theory and 2d CFT have been developed by different communities to study the linear response to perturbations of BHs and compact objects, their multipolar structure, tidal deformation properties and absorption coefficients that are crucial to model the GW signal expected from the merger of these objects and discriminate signatures of new physics at the horizon scale. We are organizing the second edition of a workshop on these topics, with the goal of bringing together scientists from different communities, backgrounds and expertise, to stimulate interdisciplinary interactions between and cross-fertilisation of ideas and techniques as diverse as gauge theories, 2d CFT, BH and GW phenomenology, string theory, and advanced numerical techniques. We aim to have only two talks per day and devote most of the time to informal discussions and to explore possible collaborations. The GGI provides the ideal environment for a fruitful and relaxed workshop, also providing office spaces for the participants. For this reason, the number of participants is limited and we suggest applying at your earliest convenience through the workshop webpage.

Gravitational waves meet effective field theories, Benasque, Spain --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=25984 Starting: 2023-08-20 to 2023-08-26 Location: Benasque, Spain Additional Information: https://www.benasque.org/2023mcs/ Contact: miguel.bezaresfigueroa[AT]nottingham.ac.uk General Relativity (GR) describes gravity on a huge range of scales, field strengths and velocities. However, despite its successes, GR has been showing its age. Cosmological data support the existence of Dark Sector, but may also be interpreted as a breakdown of our understanding of gravity. Also, GR is intrinsically incompatible with quantum field theory, and should be replaced, at high energies, by a (still unknown) quantum theory of gravity. This deadlock may prelude to a paradigm change in our understanding of gravity, possibly triggered by the direct observations of neutron stars and black holes by gravitational-wave interferometers. The recent LIGO/ Virgo observations have already made a huge impact on our theoretical understanding of gravity, by severely constraining several extensions of GR. In this workshop, we will focus on effective field theories of gravity extending/modifying GR, focusing on their predictions for the generation and propagation of gravitational waves, and on their comparison with experiments. Our goal is to establish new synergies among different communities, including numerical relativity, post-Newtonian theory, data analysis and cosmology. Invited Speakers - Karim Noui * - Cliff Burgess * - Claudia de Rham* - Antonio Padilla * - Miguel Zumalacarragui * - Filipo Vernizzi - Alessandra Silvestri - Tanja Hinderer* - Felix Julie - Luis Lehner - Pau Figueras* - Helvi Witek - Aaron Held - Maxence Corman - Leo Stein* - Harald Pfeiffer - Tessa Baker - Andrea Maselli - Dina Traykova (* to be confirmed) The workshop will include ample time for discussions and a selected number of contributed talk, and office space will be available to participants.

Scientific Programmer Position at the Max-Planck-Institute for Gravitational Physics, Potsdam, Germany ------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=25990 Deadline: 2023-02-20 Location: Potsdam, Germany Additional Information: https://www.aei.mpg.de/991039/scientific-programmer Contact: andre.schirotzek[AT]aei.mpg.de The "Astrophysical and Cosmological Relativity" division at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in Potsdam is looking for a highly motivated, talented Scientific Programmer who will actively engage in the computational research activities carried out in the division. The position will be at the level of a staff scientist; the appointment will initially be for 3 years, with the possibility of becoming permanent afterwards. In exceptional cases, the position can be made permanent sooner, or from the beginning. The "Astrophysical and Cosmological Relativity" (ACR) division, led by Alessandra Buonanno, is composed of about 40 scientists, including three permanent group leaders, Jonathan Gair, Harald Pfeiffer, Jan Steinhoff, and the five-year research group leader Miguel Zumalacarregui. The division also hosts several long and short-term visitors, and it has ties with the Physics Department at the University of Maryland, the Humboldt University in Berlin, and the University of Potsdam. Several members of the division are part of international collaborations including the LIGO Scientific Collaboration, the LISA Consortium and the Einstein Telescope Collaboration. With recent ground-breaking observations of gravitational waves by the LIGO-Virgo-KAGRA (LVK) collaboration, gravitational-wave astrophysics is an exciting, fast-growing field. One of the main research activities in the ACR division is the development of theoretical models of gravitational waves from astrophysical and cosmological sources. Such models are necessary to detect gravitational waves and extract the physical information about the extreme sources that generate them, such as black holes and neutron stars. They are also needed to test the nature of gravity itself. These models are also employed to make predictions about future more sensitive detectors, such as LISA, the Einstein Telescope and Cosmic Explorer. The ACR division plays a leading role in this pursuit, by creating and helping maintain production analyses codes (such as the LIGO Algorithm Library), and by maintaining and developing a waveform modeling toolkit called pyEOBNR (which is an effective-one-body (EOB) numerical-relativity (NR) calibrated waveform model for binary systems in the Python language). It is expected that the pyEOBNR toolkit will include ever more physical effects and be made computationally efficient for future detectors. Furthermore, evaluating waveform models can be computationally expensive and therefore the ACR division is also leading activities to accelerate gravitational-wave inference. This activity includes the maintenance and development of the machine-learning algorithm Deep INference for Gravitational-wave Observations (DINGO). DINGO uses state-of-the-art machine learning methods, such as normalizing flows, to directly infer the parameters, with uncertainties of events, observed by current ground-based gravitational-wave detectors. This inference can be done in seconds, enabling the use of the most accurate waveform models for a much wider range of scientific applications than ever before. It is anticipated that DINGO will be used for an increasing range of ACR projects over the coming years, and be extended to a wider range of source types and adapted to future detectors. It is expected that the successful candidate for this position will support the computational work of ACR scientists. The successful candidate will also participate in software development and its application to the analysis of current and future observational data. Modelling and inference work within the ACR department makes use of a high-performance computer cluster, Urania, with ~6,000 cores, a high-throughput compute cluster, Hypatia with ~12,000 cores and two GPU servers, Saraswati and Lakshmi, each with 8 A100 GPUs. Those clusters are used to run numerical-relativity simulations of gravitational-wave sources, and to carry out source modeling and data-analysis studies for current and future gravitational-wave detectors. The clusters are maintained by a full-time cluster administrator. Key tasks/responsibilities: - Support the development and maintenance of software packages used to generate waveform models (such as pyEOBNR), and used for statistical inference on the properties of observed gravitational-wave sources (such as DINGO). - Work to ensure that the computational performance of the software meets the needs of the ACR's scientists. - Ensure that software developed in the division is well documented to facilitate the easy use of the code by new members and external collaborators. - Consult and train scientists in the use of software, as needed. - Support research and publications conducted by scientists in the division. - Engage in visualization of results. Required education and experience: - Ph.D. in computer science, astronomy, physics or a related discipline. - At least 4 years of experience with high-performance computing (HPC) or high-throughput computing (HTC) resources. - Expert knowledge in computational languages used in the astrophysics and physics community (e.g., Python, C/C++, Mathematica). - Experience using multiple computational platforms (e.g., OSX, Windows, Unix/Linux). - Excellent verbal and written communication skills. - Excellent knowledge of oral and written English. Preferred qualifications: - Background in gravitational-wave physics or astrophysics. - Familiarity with gravitational-wave software. - Familiarity with modern software development practices, such as version control (Git) and continuous integration (CI). - Knowledge of machine-learning methods. - Experience in numerical solutions of ordinary and partial differential equations. For the application, you will be asked to upload a cover letter, curriculum vitae, list of publications and a statement of past and future research activities related to this job of not more than 3 pages. Applicants will need to indicate the names of three referees for recommendation letters. Please register an account with our job portal and fill in the contact information for the referees well before the deadline, so that reference letters can be received in time. Referees will receive an email with instructions on how to upload their letters. In case of problems with the application form, please contact jobs[AT]aei.mpg.de. Salary and benefits follow the remuneration of public employees in Germany ("Tarifvertrag im Oeffentlichen Dienst, TVOED"). Candidates are encouraged to apply as soon as possible. The deadline for full consideration is February 20, 2023, including reception of reference letters. The anticipated start date of the positions is Fall 2023. Applications will be considered until the position is filled.

News ============================================== 3.1. New book: Experimental Gravitation ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=25919 Additional Information: https://link.springer.com/book/10.1007/978-3-030-95596-0 A new textbook "Experimental Gravitation" has been published by Springer Lecture Notes in Physics. Authors: Fulvio Ricci and Massimo Bassan Available in print and in electronic format. https://link.springer.com/book/10.1007/978-3-030-95596-0 This book features a comprehensive review of experimental gravitation. It is a textbook based on the graduate courses on "Experimental Gravitation" taught by the authors at their respective universities in Rome: Sapienza and Tor Vergata. A number of different research topics in the field are covered: from the torsion pendulum (still today the tool of choice for measuring small forces or torques) to the large interferometers developed to observe gravitational waves. Techniques that are still under development are also discussed, like the pulsar timing array and space-based detectors of the future. This book is written by experimentalists for experimentalists. While the background physics is summarized for less experienced readers, the emphasis is certainly on experimental verifications: the strategy, the apparatuses, the data analysis and the results of many cornerstone experiments are analyzed and discussed in depth. This textbook serves as a useful resource for both graduate students and professionals working in the increasingly vibrant field of experimental gravity. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.2.

A Memoriam of Bernd Schmidt ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=26089 Additional Information: In Memoriam of Bernd Schmidt On 10th January 2023 Bernd Schmidt passed away. He is survived by his wife Christa Pauler and daughters Katrin and Nikola Schmidt. Bernd was an influential scientist whose work covered many of the aspects of general relativity which are nowadays called Mathematical Relativity. He started his research career at Hamburg University, where Pascual Jordan led an illustrious group which produced, among many others, Juergen Ehlers, Engelbert Schuecking and Rainer K. Sachs. A modern version of his 1996 diploma thesis was published in 1991 as "Existence and Properties of Spherically Symmetric Static Fluid Bodies with a Given Equation of State", co-authored with Alan Rendall. His first published paper in 1967 on "Isometry Groups with Surface-Orthogonal Trajectories" is important for understanding the geometry of spherically symmetric spacetimes and forms the basis for the treatment in Appendix B of the celebrated Hawking-Ellis monograph. The subject of spherical symmetry in general relativty remained close to Bernd's interest throughout his life. Bernd's 1972 paper on the bundle (or b-) boundary also plays a key role in description of singularities of Chapter 8 in the Hawking-Ellis monograph. When Juergen Ehlers undertook the call to create a relativity group at the Max Planck Institute for Physics and Astrophysics in Munich, he recruited Bernd to join him. Bernd remained with this group through its relocation, first at Garching and finally at Golm. In 1995, with Ehlers, Bernard Schutz and Helmut Friedrich, Bernd became a founding member of the Albert Einstein Institute at Golm, the Max Planck Institute devoted to Gravitation. Starting in 1995, he was instrumental in assisting the founding Directors in designing and staffing the new Institute. After his retirement in 2007 he moved back to Munich, where he continued research until his death. Bernd recently presented a talk in Golm on the history of the Institute. In the week following his return to Munich he became afflicted with a fatal brain abscess. Bernd's research contributions are striking in their breadth. The subjects range from purely geometric topics such as spacetime isometry groups and the theory of connections, to subjects of physical importance such as spacetime singularities, the asymptotic structure of the gravitational field, exact solutions of the Einstein equations, mathematical cosmology, stellar oscillations, relativistic elasticity, quasi-normal modes and aspects of numerical relativity. His comprehensive Living Review with Kostas Kokkatas on "Quasi-Normal modes of Stars and Black Holes" has provided an important resource for numerous perturbation studies which have been a main topic in relativistic astrophysics. In particular, the review has gained particular importance from the recent observations of gravitational waves from binary inspirals, where quasi-normal modes dominate the final ringdown of the waveform. His work on boost-symmetric spacetimes with Jiri Bicak, and the analysis of various aspects of the asymptotic structure of spatial and null infinity has led to a number of important advances. Thanks to his more recent work with Robert Beig, elasticity has now become an interesting new area of research in mathematical general relativity. Their collaboration continued until Bernd's last publication, "Mechanics of Floating Bodies" (2021). Bernd was insightful and perceptive in both research and friendship. Many mathematical relativists were drawn to the Albert Einstein Institute for long visits because of Bernd's presence. A great many colleagues in this community will share our appreciation of his advice, professional support and research input. His clarity of thought and friendly help went beyond his own specialties and spanned all aspects of general relativity. This was immediately apparent to those who benefited from interacting with him and was perhaps his most important contribution to the field.
