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!

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.
