Description
Gamma-ray astronomy explores the most powerful phenomena in the Universe, addressing fundamental questions in particle astrophysics ranging from powerful astrophysical jets and extreme physics of compact objects to the nature of dark matter and the origin of gamma-ray bursts. The Fermi Gamma-ray Space Telescope has profoundly advanced the field of high-energy astrophysics through continuous, high-sensitivity monitoring of the gamma-ray sky. Utilizing its Large Area Telescope (LAT) and Gamma-ray Burst Monitor (GBM), Fermi has compiled extensive catalogs encompassing thousands of gamma-ray sources, including pulsars, supernova remnants, and active galactic nuclei (AGN) such as blazars. The Cherenkov Telescope Array Observatory (CTAO ) will extend the observations up to 300 TeV and will operate arrays on sites in both hemispheres to provide full sky coverage and will hence maximise the potential for the rarest phenomena such as very nearby supernovae, gamma-ray bursts, or gravitational wave transients, In my lecture I will review some of the new results and the prospects for the future.
