Gravity2026: New Frontiers in Cosmology, April 27 – May 1 2026 in Daejeon The aim of the workshop is to foster comprehensive and in-depth discussions on the rapidly expanding frontiers of gravitational physics. The program will cover a wide spectrum of topics central to cosmology, including gravitational waves, early- and late-time cosmology, and theories of modified gravity. Workshop Website

WE Heraeus Physics School und 62. Karpacz Winter School in Theoretical Physics „Multimessenger Astrophysics and Cosmology“, February 28 – March 6 2026 in Karpacz With next-generation observatories like the Einstein Telescope and Cosmic Explorer, multi-messenger astrophysics—combining gravitational waves, electromagnetic signals, and neutrinos—will sharpen constraints on the dense-matter equation of state, extreme gravity, and heavy-element nucleosynthesis. Mergers also serve as standard sirens, enabling independent measurements of the Hubble constant. The school will cover the thermal history of the Universe after its first second, from the quark–hadron transition to neutrino decoupling, linking microphysics to cosmological observables.

Einstein Telescope science workshop for early career Researchers, February 18-20, 2026 at Sapienza University of Rome The workshop wants to bring together young researchers actively involved in the activities of the Observational Science Board (OSB), Instrumental Science Board (ISB) and Site Characterization Board (SCB) of the Einstein Telescope. Leaving plenty of room for discussions, it will be a great occasion to share research and ideas, start projects, learn about new topics, and build collaborations. Workshop Website

Neutron Stars: Modelling and Detection – SIGRAV International School 2026, February 16-20 in Vietri sul Mare This edition of the Italian Society of General Relativity and Gravitation (SIGRAV) International School is dedicated to the study of neutron stars as outstanding sources of gravitational and electromagnetic waves in the strong-field regime.

YOUNGST@RS – Lost in Translation: The languages of Gravitational Waves, January 19-21 2026 at University of Mainz The workshop aims to bridge this gap and bring these communities closer together. This will be done by providing a mix of beginner friendly lectures, hands on coding sessions, plenary overviews together with state of the art research talks for each of the fields. Workshp Website

Summer school on Multimessenger Astrophysics at ICE in Barcelona, July 6-14 2026 9th edition of the ICE Summer School devoted to Multimessenger Astrophysics. This intensive programme is designed for advanced Master’s and PhD students, early-career researchers, andothers interested in the physics and observational techniques associated with multimessenger phenomena in the universe.

Kavli-IAU Global Coordination Workshop (GCW) “International Coordination of the Time – Domain and Multi-Messenger Sky: New Opportunities and New Challenges”, Görlitz, Germany, 22-26 June 2026 The workshop, to be hosted at the new German Centre for Astrophysics (DZA) in June 2026, builds on the highly successful Kavli-IAU Global Coordination Workshop series. This will bring together approximately 50 astronomers and astrophysicists from around the world to discuss the global considerations of time-domain astronomy and multimessenger astrophysics. The drivers for these areas over the next decade will be large, international projects which require prompt and coordinated follow-up of new astronomical discoveries that may disappear in just a few days, or even sooner.…
