The Cherenkov Telescope Array Observatory (CTAO) is proud to be a major contributor to the 33rd General Assembly of the International Astronomical Union (IAU), taking place in the historical city of Rome, Italy.
As the world's largest and most sensitive high-energy gamma-ray observatory, CTAO is ushering in a new era of multi-messenger astrophysics. This dedicated symposium within the IAU 2027 framework will gather astronomers, particle physicists, and multi-wavelength/multi-messenger partners from across the globe to discuss cutting-edge research, synergies, and the transformative science CTAO will deliver.
Whether your focus is on galactic accelerators, transient phenomena, or fundamental physics, we invite you to join us in Rome to shape the future of high-energy astrophysics.
