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.…

Tales of Black Holes – International Doctoral Summer School on Advanced Black Hole Physics, June 29 – July 3, 2026, Granada Black holes are among the most fascinating objects in the universe. From cosmological, galactic and stellar scales, where black holes are integral pieces in the formation and evolution of different structures, to microscopic scales, where the study of the fabric of spacetime and black hole interiors are interrelated, black holes are ubiquitous in all research areas in which gravity is a prominent actor. A proper understanding of many aspects of modern physics requires being familiar with the concept of black hole; conversely, comprehending black holes in all their dimensions…

Causalworlds 2026: The 3rd International Conference on Quantum, Classical, and Relativistic Causality, June 22-26, 2026, Grenoble Understanding causality is foundational to science and has wide-ranging applications, yet there are several distinct notions of causation. Recently, there have been important developments on the role of causality in quantum physics, relativistic physics and their interplay. These have unearthed a plethora of deep and fascinating questions regarding the nature of causation in physical theories, emergence of space-time structure and how relativistic principles can shape the landscape of quantum information processing.

Dark Matter and Stars: Multi-Messenger Probes of Dark Matter and Modified Gravity, July 13-15 2026, Southampton The International Conference „Dark Matter and Stars: Multi-Messenger Probes of Dark Matter and Modified Gravity“ aims to bring together scientists working across the different research fields of astrophysics, cosmology, and modified gravity. We want to look at the dark matter problem from different perspectives, considering it to be of particle nature, as well as modification of gravity. This meeting is intended to initiate cross-field discussions of dark matter searches, their current status, and future prospects. Conference Website

CosPA2026 and ACGRG13, July 6-10 2026, Christchurch, New Zealand The International Symposium on Cosmology and Particle Astrophysics (CosPA2026) and the 13th Australasian Conference on General Relativity and Gravitation (ACGRG13) will be held jointly, bringing together two complementary scientific communities. CosPA2026 is part of an annual conference series organized in the Asia-Pacific region under the Asia Pacific Organization of Cosmology and Particle Astrophysics (APCosPA), while ACGRG13, convened by the Australasian Society for General Relativity and Gravitation, is a biennial forum for regional researchers in all areas gravitational physics from mathematical relativity to experimental gravitational wave detection.

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…
