Advancing gravitational wave predictions from cosmological first-order phase transitions, August 25–29 2025 at CERN As the detection of a stochastic gravitational wave background from the early universe becomes increasingly promising, signals from hypothetical first-order phase transitions are attracting growing interest. Predicting these signals often requires the solution of plasma dynamics at macroscopic scales, which, in turn, depends on the phenomena that characterize the phase transition at microscopic scales. Therefore, various assumptions on distinctive scales and their separation are usually employed to enable concrete evaluations. Workshop Website

Mathematical Methods for the General Relativistic Two-body Problem August 11-15 2025, Singapore This week-long IMS workshop provides a chance for researchers from relevant communities to work together on solving the remaining challenges in the modelling and interpretation of gravitational waves from asymmetric binary systems. The workshop will be structured along three main themes: theory, computation, and science. Each theme will be addressed through a combination of invited talks and discussion sessions.

Nonlinear Black Hole Perturbation Theory: Merging Black Holes, Communities and Ideas, September 15-17 2025 at University of Nottingham Black hole perturbation theory has been a key driver of theoretical gravity research since the 1960s, illuminating aspects of quantum gravity, information theory, gravitational-wave science, and the fundamental nature of black holes. It has played a particularly important role in two areas: self-force theory, used to model asymmetric binaries such as extreme-mass-ratio inspirals; and ringdown studies of dynamical black holes, such as occurs after a black hole merger.

1st UNDARK workshop: astrophysical searches of dark sectors with radiowave observations, September 29 – October 3 2025, La Laguna, Tenerife The 1st UNDARK workshop which will be held in Tenerife during the week Sept 29 – Oct 2rd 2025. This workshop will focus on astrophysical probes of fundamental questions related to the dark universe, with a specific emphasis on radio wave observations, as well as their possible connections with gravitational wave detection. The meeting is organized in the context of the UNDARK project and it aligns with the observational and instrumental expertise of the Instituto de Astrofísica de Canarias (IAC) in microwave astronomy.

Summer School on String Theory and Summer School on Gravitational Waves, July 31 – August 10, 2025 On the theory and phenomenology tracks of PSI, we are organizing two schools in parallel—one on String Theory and the other on Gravitational Waves. School Website

First International Latin American Conference on Gravitational Waves: 10 years since first detection September 15–19 2025 at INPE Sao Paulo 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.
