We are delighted to invite you to the 4th International Summit on Gravitation,
We are thrilled to invite you to the 4th International Summit on Gravitation, Astrophysics, and Cosmology (ISGAC2026), happening April 20–22, 2026, in Frankfurt, Germany. This premier international gathering will unite leading scientists, researchers, and innovators from around the world to explore the latest breakthroughs in gravitation, astrophysics, and cosmology.
Building on the success of ISGAC2023 in Rome, ISGAC2024 in Florence, and the upcoming ISGAC2025 in March 2025, ISGAC2026 continues our tradition of fostering collaboration and advancing discovery across these exciting fields. Together, we will celebrate how far we’ve come—and chart bold new directions for the future of gravitational physics and cosmology.
ISGAC2026 will feature cutting-edge sessions on topics including:
-
Gravitational Physics and Lensing
-
Wave–Particle Duality
-
Applied Relativity
-
Stellar and Solar Physics
-
Alternative Theories of Gravity
-
Jet Physics and Neutrino Cosmology
The summit will host distinguished keynote speakers from leading universities and industry, offering powerful insights and sparking dynamic, thought-provoking discussions.
Join us in Frankfurt for three inspiring days of science, collaboration, and discovery. We look forward to welcoming you to ISGAC2026!
