Rest-frame statistics of 32 GBM-GRBs.

摘要

For many years the peak energy and duration distributions of gamma-ray bursts (GRBs) have been studied in the observer frame, which does not provide information about the intrinsic spectral properties of the event. In this paper, we study the sample of 32 GRBs that have measured redshift and were observed with the Fermi Gamma-ray Burst Monitor (GBM) up to October 16th, 2010. We reconstruct their intrinsic spectral (E_(p,rest)) and temporal (T_(90,rest)) properties.
