Abstract |
The physical origin of the temporally extended (>100 seconds) high-energy emission (0.1-100 GeV) detected from Gamma-Ray Bursts (GRB) has not been completely understood. Most of our present knowledge on its temporal and spectral properties is currently based on observations by the Fermi/LAT, that has detected radiation in the range 40 MeV-100 GeV from about 150 GRBs. Its origin and relation to the emission detected at lower frequencies are still uncertain. In this talk, I will discuss the physical origin of GeV radiation and stress the potential of GeV observations and modeling for improving our still poor understanding of the processes producing radiation in GRB jets. |
