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.

Quantum Gravity and Cosmology 2026, February 9-13, Bologna The goal of the workshop is to bring together the experts working on different UV complete approaches to quantum gravity, from string theory to various perturbative and non-perturbative approaches. Given the promising opportunity to probe quantum gravity effects in the very early Universe with future CMB and gravitational wave experiments, we expect the in-depth discussions on predictions and self-consistency of low- energy effective theories on top of cosmological backgrounds.

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.

42nd Pacific Coast Gravity Meeting – February 27-28, 2026 at UC Riverside In the tradition of the Pacific Coast Gravity Meetings, students and postdocs are strongly encouraged to participate, and all areas of gravitational physics—classical and quantum, theory and experiment—are welcome. We would like this meeting to serve as a communication medium among all branches of gravitational physics. Because this is a regional APS meeting, many participants will be from the Western U.S., but all are welcome. Conference Website

Symposium & Memorial for Professor Rainer Weiss, Fri-Sat February 27–28, 2026 The MIT Department of Physics and Kavli Institute for Astrophysics and Space Research would like to share with you plans for a symposium and memorial service honoring Professor Rainer Weiss, Nobel Laureate in Physics (2017) and longtime member of our faculty, whose visionary work made the discovery of gravitational waves possible.
