Rest-frame properties of 32 gamma-ray bursts observed by the Fermi Gamma-Ray Burst Monitor

Understand

Aims: In this paper we study the main spectral and temporal properties of gamma-ray bursts (GRBs) observed by Fermi/GBM.

• We investigate these key properties of GRBs in the rest-frame of the progenitor and test for possible intra-parameter correlations to better understand the intrinsic nature of these events.
• Methods: Our sample comprises 32 GRBs with measured redshift that were observed by GBM until August 2010.
• 28 of them belong to the long-duration population and 4 events were classified as short/hard bursts.
