GRBs observation at High and Very High Energy

Gamma Ray Bursts are among the most powerful astrophysical phenomena. In the recent past many observations shed light on their high-energy (HE, E>10 MeV) emission properties. In the seminar I will describe the observations of GRBs by the currently operating HE satellites AGILE and Fermi. I will discuss the main observational properties of the detected bursts and their main theoretical interpretations. At very high energies (E>100 GeV) the detection of GRBs by currently operating Imaging Atmospheric Cherenkov telescopes is still missing. Based on the observation of GRBs at lower energies, I will discuss the prospects of GRB detection by future VHE facilities, like the Cherenkov Telescope Array.
