Prospects in Theoretical Physics 2025:Gravitational Waves from Theory to Observation, July 14-25, 2025, Princeton PiTP is an intensive two-week summer program designed for advanced graduate students and postdoctoral scholars. The program will be held from July 14-25, 2025 at the Institute for Advanced Study, Princeton, NJ. The school will explore the field of gravitational wave physics and astrophysics, bridging the gap between theory and observation. Gravitational waves offer a unique window into the Universe, allowing us to probe extreme astrophysical environments and primordial cosmological epochs. School Website

Workshop on „Gravitational Wave Cosmology“, February 19-21, 2025 in Brussels The aim of this workshop is to bring together experts working in diverse fields of observational cosmology to address pressing questions that the new observations are currently bringing such as: How can we distinguish cosmological sources from the detected Pulsar Timing Array signal? What is the nature of the Hubble tension: systematic errors or a sign for new physics? How will gravitational waves standard sirens contribute in the near future? How to distinguish the primordial gravitational wave background from the astrophysical background? Which notable multi-messenger signatures should be searched for? Workshop Website

EMRI Search and Inference within the LISA Global Fit – Part I, June 23–25 2025, APC Paris The aim of this workshop is to bring together experts in EMRI science and LISA data analysis, to assess the state of the art in the field and to further develop plans for the optimal extraction of science from such sources.

3rd LISA Sprint, April 28-30, 2025 in Huntsville The Laser Interferometer Space Antenna (LISA) is a joint effort of ESA and NASA to develop and operate the first space-based observatory of gravitational waves (GWs) in the millihertz frequency band. To prepare for LISA observations and its unique data products, we are organizing the 3rd LISA Sprint in Huntsville, AL, from Monday April 28 to Wednesday April 30, 2025. Read more

LVK Collaboration Meeting, March 24-27 2025, Melbourne We are delighted to host the 2025 March LIGO-Virgo-KAGRA (LVK) Collaboration Meeting in Melbourne, Australia, from March 24th – 27th at the Pullman Melbourne Albert Park Hotel. This year’s meeting will be hosted by the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav). Meeting Website

11th Gulf Coast Gravity Meeting, April 11-12, 2025 at University of Mississippi The GCGM returns to the University of Mississippi! The 11th Gulf Coast Gravity Meeting will be held at the University of Mississippi in Oxford, MS, on April 11 and 12, 2025. In keeping with its tradition, this will be an open, relaxed, and informal conference. We are inviting researchers and students interested in all areas of gravitational physics: classical and quantum gravity, general relativistic astrophysics and cosmology, quantum cosmology, gravitational waves, and experimental gravity. Because this is a regional meeting, many attendees will be from the southeastern United States, but all are welcome. Meeting Website

Einstein Telescope German Community Annual Meeting, January 30-31, 2025 in Hamburg The German Einstein Telescope Community is invited to a face-to-face meeting in Hamburg to present status and perspectives in Gravitational Wave Astronomy. Current German activities towards the realization of the Einstein Telescope (ET) and the status within the international community will be presented and discussed in view of a German contribution to this future Gravitational Wave interferometer.
