WE-Heraeus-Seminar "Gravitational Wave and Multimessenger Astronomy", Bad Honnef, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2021/12/08/we-heraeus-seminar-gravitatio... Starting: 2022-04-25 to 2022-04-28 Location: Bad Honnef, Germany Additional Information: https://www.we-heraeus-stiftung.de/veranstaltungen/gravitational-wave-and-mu... Contact: gravWaves-heraeus[AT]aei.mpg.de Gravitational waves are the only way to access the dark side of the Universe that is invisible to other instruments. The large number and properties of the detected black hole binaries already challenge our understanding of their formation. Furthermore, other cataclysmic events like the merger of neutron stars emit gravitational waves and other "messengers", such as electromagnetic radiation and neutrinos. In this new era of multimessenger astronomy, all information must be combined to unravel more secrets of the expanding Universe, matter at extreme densities, gamma-ray bursts and much more. This workshop will bring together pioneers and experts of this new era and a new generation of astronomers who will use all available tools to advance the field in the future. Introductory talks will not only summarize the status quo but also look into the future of instrumental developments, data analysis, astronomy and astrophysics. In addition, tutorials will offer hands-on experience with these new types of data and software, and participants will have ample opportunity to discuss the future of a field that has just begun. WE-Heraeus Seminars are fully funded seminars focussing on broadly accessible expert talks and tutorials. There is plenty of time to interact at the magnificent Physikzentrum Bad Honnef that serves as the conference venue and accommodation for all participants. Spaces are limited! Applicants will be selected based on their motivation, ensuring appropriate diversity in research interests, career stage, home institution, gender and other aspects. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1.2. Global Structure in Semi-Classical Gravity, Munich, Germany --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2021/12/18/global-structure-in-semi-clas... Starting: 2022-07-21 to 2022-07-23 Location: Munich, Germany Additional Information: https://www.mcmp.philosophie.uni-muenchen.de/events/workshops/container/scg2... Contact: erik.curiel[AT]lmu.de Semi-classical gravity (SCG)---the coupling of the dynamics of quantum fields to the classical spacetime geometry of general relativity by way of the semi-classical Einstein field equation (SCEFE)---is the framework within which black hole thermodynamics is formulated. As such, it is widely held to provide the most secure theoretical clues to a search for a theory of quantum gravity. Considered in its own right, however, it already presents us with a plethora of foundational and conceptual problems that require investigation, even over and above the most famous one, Hawking's Information-Loss Paradox. - In what sense is it legitimate to think of black holes as thermodynamical systems? - What is the causal structure of an evaporating black hole spacetime, and its relation to causality conditions on quantum fields? - What is black hole entropy? - How does the Generalized Second Law ramify into the host of other problems of fundamental physical and philosophical import that the ordinary Second Law of thermodynamics does? - What is the difference between geometry and matter? - Are there singularities in the semi-classical regime, and does a form of cosmic censorship hold in it? - What role do classical energy conditions and quantum energy inequalities play, and how do they relate to entropy and information? - What is holography at the semi-classical level, and what role can or does it play there? - What can the epistemology of a field of physics be, completely divorced from experimentation and observation? This will be the first major conference to address foundational and philosophical issues associated with SCG, and to try to examine how they all bear on each other. Invited physicists and philosophers have been chosen to represent different approaches to SCG and the many different kinds of conceptual questions it poses (quantum field theory on curved spacetime, emergent gravity, canonical gravity, holography, phenomenology, methodology, epistemology), in an attempt to foster a dialogue among the different fields. Contributed talks from both physicists and philosophers will be chosen so as to complement the perspectives of the invited speakers. Such a gathering will spur new, innovative approaches to the problem, as well as connecting and invigorating work on existing approaches. It will also provide young researchers with a comprehensive introduction to the state of the art of this central field of research, and established researchers with a comprehensive overview. *Confirmed Speakers* - Beatrice Bonga - Craig Callender - Ted Jacobson - Eleni Kontou - JB Manchak - Marija Tomasevic - Chris Smeenk - Bob Wald - Chris Wuethrich *Call for Abstracts* We invite the submission of paper abstracts for the conference. Abstracts should include a title, a brief abstract (up to 200 words), and a full abstract (up to 1000 words), blinded for peer review.

Information Architecture of Spacetime, Okinawa, Japan (hybrid online) --------------------------------------------------------------- Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/2021/12/22/information-architecture-of-s... Starting: 2022-05-30 to 2022-06-03 Location: Okinawa, Japan Additional Information: https://groups.oist.jp/iasw Contact: joshua.kirklin[AT]oist.jp The emerging information paradigm is leading to deep new insights into the structure of spacetime. Many results, in various approaches, suggest that its large-scale structure can be understood as emerging from quantum correlations of more fundamental degrees of freedom. An intriguing picture arises that portrays the architecture of spacetime as a network of quantum degrees of freedom exchanging information and in which quantum correlations assume the role of the "glue" that holds spacetime together. These insights not only hint at a universal emergence mechanism for spacetime structures, but also offer new perspectives on various established topics, including black holes, the dynamics of spacetime, spacetime thermodynamics, and information processing in spacetime. Drawing from multiple research areas, these developments have led to prolific cross-fertilizations and a novel multidisciplinary research community. The Informational Architecture of Spacetime Workshop brings together leading experts at the interface of quantum gravity, quantum information theory, quantum many-body physics and quantum foundations to discuss contemporary research on understanding spacetime from an informational perspective. The following four main topics will be broadly covered during the meeting: Black Holes and Information Entanglement, Complexity and Geometry Quantum Many-Body Techniques in Quantum Gravity Quantum Information, Foundations and Spacetime ���Talks are by invitation only. At present, we are aiming for a hybrid format with both in-person (mostly speakers and local audience) and online participation. Talks will be made available by livestream. Zoom links will be provided after registration. Depending on the situation due to the covid-19 pandemic, the workshop may however be moved fully online. Relevant updates will be announced once available. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ============================================== 2.

News ============================================== 3.1. Prof. Jerzy Jurkiewicz passed away on November 30, 2021 ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=24073 Additional Information: It is with deep sorrow that we learned on November 30, 2021, of the unexpected passing of our Colleague, Prof. Jerzy Jurkiewicz. He was 74 years old. Jerzy Jurkiewicz was born on July 22, 1947, in Krakow. In 1970 he received a master's degree in physics, and in 1975 a doctoral degree in physics at the Jagiellonian University in Cracow (JU). In 1987 Jerzy Jurkiewicz was awarded a postdoctoral degree (habilitation), and in 1997 he became a full professor. In 2009-2012 he was the Dean of the Faculty of Physics, Astronomy and Applied Computer Science at the JU; for many years he was the head of the Theory of Complex Systems Department of the Institute of Physics at the JU, the founder and head of the Mark Kac Complex Systems Research Center at the JU and a member of the Senate of the JU. In 2018 he was awarded the "Jagiellonian Laurel" ("Laur Jagiellonski") for outstanding scientific achievements. Professor Jerzy Jurkiewicz was an active member of the Division III of Science and Technology of the Polish Academy of Arts and Sciences (PAU), a member of the PAU Board of Directors in years 2018-2021 and a chairman of the PAU Complex Systems Commission. He was the initiator and chairman of the Marian Smoluchowski Krakow Scientific Consortium, which was granted the status of National Leading Scientific Centre (KNOW) in physics in 2012. He was also one of the initiators, a founding member and former Vice President of the Polish Society on Relativity. Prof. Jerzy Jurkiewicz was one of the most eminent Polish theoretical physicists, a world-renowned scientist, an expert in the fields of quantum gravity, strong interactions, complex systems and random matrices, mathematical physics and its applications, and numerical simulations of quantum systems using the so-called lattice regularization. Prof. Jurkiewicz became famous, together with Prof. Jan Ambjorn and Prof. Renate Loll, as the creator of the model of Causal Dynamical Triangulations (CDT). Earlier, together with Prof. Ambjorn, he also invented a model of the so-called Euclidean Dynamical Triangulations. Both models are an attempt at a non-perturbative formulation of the theory of quantum gravity aimed at unifying two fundamental areas of theoretical physics - quantum mechanics and the theory of gravity. The CDT model has proven to be one of the most promising research directions in the quest for a theory of quantum gravity, allowing the analysis of quantum-gravitational effects using advanced computer simulations. In particular, the research group led by Prof. Jurkiewicz succeeded in showing the existence of a correct semiclassical limit of the CDT model, consistent with Einstein's theory of gravity, was one of the first to observe the existence of scale dependence of the effective dimension of quantum spacetime (so-called dimensional reduction), demonstrated the presence of higher order phase transitions in CDT, which gives hope for the formulation of a continuum limit of this model, analyzed the influence of spacetime topology on the phase structure of CDT, demonstrated the existence of a non-trivial effect of matter fields on the topology of quantum space-time. In addition to his work on the theory of quantum gravity, Prof. Jerzy Jurkiewicz was also very active in the field of research on lattice QCD and on random matrix theory and its application to the analysis of complex systems, including the study of physical phenomena, economics, financial markets, biological phenomena, analysis of random networks and surfaces. Prof. Jurkiewicz enjoyed great recognition in the international scientific community. He was repeatedly invited to the world's leading scientific centers. Among longer research stays, it is worth mentioning the University of Utrecht (1979-80, 1984-86), the University of Marseille (1982), the European Organization for Nuclear Research (CERN) in Geneva (1983), the University of Paris-Sud in Orsay (1983-84, 1996), the Niels Bohr Institute in Copenhagen (1990-91, 1994-95, 1997-98). Jerzy Jurkiewicz cooperated with and was a friend of many recognized scientists, among others with Prof. Jan Ambjorn, Prof. Renate Loll, Prof. Maciej Nowak, Prof. Zdzislaw Burda, Prof. Andrzej Krzywicki, Prof. Chris Korthals-Altes, Prof. Gerardemus 't Hooft, Prof. Martinus Veltman. He was repeatedly invited to organizing committees of prestigious international scientific conferences and was a plenary speaker at key scientific conferences in the field of gravitational, random matrix or complex systems research. Professor Jurkiewicz was also an extremely active organizer and leader of research projects. He was, among others, the coordinator of a significant European grant COCOS (Correlations in Complex Systems), the head of research groups in European programmes (EUROGRID, ENRAGE projects), co-organizer of the European Science Foundation project, member of the COPIRA Centre of Excellence, principal investigator of numerous KBN and NCN grants, including NCN MAESTRO.

Summary: We review the current status of general relativistic studies for coalescences of black hole-neutron star binaries. We summarize our understanding for the merger process, tidal disruption and its criterion, properties of the merger remnant and ejected material, gravitational waveforms, and gravitational-wave spectra. We also discuss expected electromagnetic counterparts to black hole-neutron star coalescences. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 3.4. New Einstein Toolkit Release (Johnson) ------------------------------------------------------------ Announcement on Hyperspace@GU: https://hyperspace.uni-frankfurt.de/?p=24113 Additional Information: https://einsteintoolkit.org/about/releases/ET_2021_11_announcement.html Release Announcement We are pleased to announce the twenty-third release (code name "Katherine Johnson") of the Einstein Toolkit, an open-source, community developed software infrastructure for relativistic astrophysics. The highlights of this release include: * The inclusion of a new code in the Toolkit release, Kuibit * The inclusion of a new code in the Toolkit release, RePrimAn In addition, bug fixes accumulated since the previous release in May 2021 have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems that builds on numerous software efforts in the numerical relativity community including code 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 GRHydro and IllinoisGRMHD. 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. For more information about using or contributing to the Einstein Toolkit, or to join the Einstein Toolkit Consortium, please visit our web pages at http://einsteintoolkit.org, or contact the users mailing list users[AT]einsteintoolkit.org.
