The Interplay of Magnetic Fields, Nuclear Physics, and Nucleosynthesis in Neutron-Star Mergers and Supernovae, September 21-25 2026 in Trento ECT*-EMMI/GSI workshop . Neutron-star mergers and core-collapse supernovae are among the most promising sites for the synthesis of heavy elements in the universe. These astrophysical phenomena bring together a rich interplay of general relativity, neutrino physics, nuclear reactions, and magneto-hydrodynamics. Among these factors, magnetic fields are increasingly recognized as playing a pivotal role in shaping the dynamics and nucleosynthetic outcomes of these events. Workshop Website

Binary compact objects on eccentric orbits and their gravitational-wave signatures, September 1-6 2026, Corfu The workshop will bring together experts in theory, numerical relativity, data analysis, and astrophysics, as well as early-career researchers entering these fields. We aim to create a collaborative environment where participants can share results, exchange ideas, and identify the next key steps. Workshop Website

CosmoVerse@Bilbao 2026, September 15-19 Our understanding of the Universe is at a turning point with the predictions of the standard cosmological model and the observations from different surveys are showing tensions in several key areas. The disagreement is expressed in the value of cosmic expansion as well as in the growth of large-scale structure in the Universe. New cosmological surveys, many of which are European, may expose tension in additional areas of the concordance model. Conference Website

From Black Holes to the Cosmos, August 24-28 at SISSA, Trieste This conference honors the scientific legacy of Matt Visser, whose pioneering work has profoundly influenced our understanding of general relativity, quantum field theory in curved spacetime, wormholes, energy conditions, analogue gravity, and beyond.

SIGRAV International School 2026: Neutron Stars: Modelling and Detection, 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. The program is structured to promote scholarly interaction and collaboration, offering participants the opportunity to engage with leading experts in the field. Through a series of advanced lectures and discussions, the School aims to provide a comprehensive understanding of current developments in gravitational research and to equip attendees with the knowledge and tools necessary to advance their own scientific work in…

Listening to the Cosmos: New Frontiers in Gravitational Wave Physics, Aug 24 – Sep 26, 2026, Firenze The first detection of gravitational waves from the Ligo-Virgo-Kagra collaboration and the recent results of several pulsar timing arrays have opened the exploration of the gravitational wave Universe. Over the next decade, several other ground and space-based experiments will join this exploration and allow us to access a broad band of the gravitational wave spectrum. This new exploration comes with a series of challenges that can only be overcome through close collaboration between experimentalists and theorists. This workshop will bring together experts working on the experiments enabling this exploration, as well as particle…
