Materials for Advanced Detectors 2026 (MAD26)Workshop, October 12-14 2026, Villeurbanne, France MAD Workshop is an excellent opportunity to connect with collegues involved in the development of advanced materials for gravitational wave detectors as well as with researchers from crystal growth community and industry who share a deep interest in the topic. Together we will discuss recent achievements and challenges in material research and outline prospects for future cooperation. We are confident that face-to-face workshops with a lot of space for personal interaction and individual meetings will contribute to achieving our common goals. Workshop Website

Multi-messenger lensing at Lorentz Center, October 19-23, 2026 This workshop aims to catalyze the emerging field of multi-messenger gravitational lensing—a transformative approach to observing the distant Universe through the combined signals of gravitational waves, neutrinos, and electromagnetic messengers from gravitationally lensed transient events. The scientific motivation lies in the potential for such lensing events to unlock new insights into cataclysmic cosmic phenomena, from kilonovae, supernovae and gamma-ray bursts to binary neutron star mergers, offering a deeper understanding of astrophysics, cosmology, and fundamental physics. Through highly interactive sessions, the workshop will identify research priorities, foster coordination among facilities, and establish a roadmap for future work to enable the first detection of…

RESCEU-NBIA workshop on gravitational-wave sources 2026, November 25 – December 4, in Tokyo The workshop will focus on compact object binaries ranging from stellar mass objects to supermassive black holes. The workshop aims to discuss our current understanding of gravitational-wave sources based on the previous gravitational-wave and electromagnetic observations and what we will be able to learn from future observations.

After the Avalanche: Astrophysical Lessons from the fourth GW observing run, February 22-26, 2027 in Sexten How binary black holes and neutron stars form and merge is the central question in gravitational-wave astrophysics. A decade after the first direct detection of a binary black hole merger, it remains unclear which gravitational-wave events probe the evolution of isolated massive binary stars, the dynamics of dense environments like star clusters, and active galactic nuclei, or more exotic pathways. One of the main hurdles has been the low-number statistics that prevented statistically robust identification of sub-populations within the observed population of gravitational-waves.

New Horizons in Quantum Gravity, April 11-16 2027 at Ecole de Physique des Houches Taking place at the prestigious Ecole de Physique des Houches near Mont Blanc, on April 11-16, 2027, this doctoral school is dedicated to young researchers in classical and quantum gravity. It covers advanced topics in general relativity -covariant phase space, boundary symmetries, edge modes- and the recent developments they led to in quantum gravity, including algebra of observables, celestial holography and the blooming interface with quantum reference frames. Leading researchers at the forefront of quantum gravity and quantum information, will teach the fundamentals and discuss the current exciting lines of research. School Website

Cosmology from Home 2026, September 21st – October 2nd Cosmology from Home is an annual online cosmology conference with an innovative format, which produces a dynamic and collaborative workshop experience within the online domain. The format includes the use of pre-recorded talks, and a combination of asynchronous and scheduled live discussions. A permanently available and freely-navigated discussion space also facilitates ongoing, organic discussions. The conference will bring together cosmologists from around the world to discuss the current state of cosmology at the interface of theory and observations. Conference Website
