Abstract

As soon as the catalog of gamma-ray bursts (GRBs) detected by the BATSE (Burst And Transient Source Experiment) had enough events to allow a statistical study, it was discovered that GRB light curves could be separated into two families [45]. Long GRBs are characterized by a duration of more than 2 seconds and a somewhat soft spectrum. Short GRBs, on the other hand, are characterized by a duration of less than 2 seconds and a harder spectrum.
