EREP 2025, Spanish and Portuguese Relativity Meeting, September 1-5, 2025, Alicante The Spanish-Portuguese Relativity Meetings (EREPs) are a long-standing scientific tradition that began in 1977. Since then, they have served as a key forum for the Portuguese and Spanish communities working in General Relativity and Gravitation, promoting collaboration and the exchange of ideas across a broad range of topics.

SN2025gw: First IGWN Symposium on Core Collapse Supernova Gravitational Wave Theory and Detection, Warsaw, July 21-25, 2025 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). Symposium Website

Multimessenger Astronomy in the Era of Foundational AI at Vanderbilt University, August 4-5, 2025 Two immersive days exploring how large foundation models, transformers, diffusion models, self-supervised learners can accelerate astronomical discovery. Experts from gravitational-wave astronomy, multimessenger astronomy, and AI will share insights through talks and panel discussions. Workshop Website

APPEC Tech Forum Vacuum & Cryogenics – Industry meets Academia, November 24-26, 2025, Maastricht European physicists in astro-particle physics as well as in neighboring fields are planning the next generation of experiments to be built within the next decade. The success of the projects in direct dark matter detection, low energy neutrino physics, neutrino properties, gravitational wave detection as well as related accelerator-based experiments in particle and nuclear physics highly depends on challenging technologies in the domain of vacuum and cryogenics.

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