Massive Black Hole Spin Workshop, April 21-24 2026, Edinburgh Astrophysical black holes can be entirely described by just two properties: their mass and their spin. While masses of black holes have been extensively studied, black hole spin remains poorly understood. This is because spin is both much more difficult to observe and more complex to model. Nevertheless, spin is no less integral to the evolution of massive black holes over time, and the role they play in shaping their host galaxies. Workshop Website

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…
