Abstract
We present results of an analysis of a sample of bright Gamma-Ray Bursts (GRBs) detected by Fermi-GBM up to more than 1 MeV, which were collected during six years of Fermi operations. In particular, we focus on the GRB durations over several energy bands of the prompt emission of a subsample of bright GRBs detected up to 10 MeV by GBM and, when possible, up to 1 GeV by Fermi-LAT, thus expanding the Duration-Energy relationship in GRB light curves to high energies for the first time. We find that the relationship for these energetic GRBs is flatter than reported for other samples, suggesting that the high- and low-energy emission mechanisms are closely related.
