Analysis of the Structure of gamma Ray Burst Time Histories

摘要

If gamma-ray bursts (GRB) arise from a small number of distinctly differentphysical phenomena, then this might be revealed by a clustering of time profile characteristics into a small number of groups. A 'spike' counting algorithm was applied to 107 GRB profiles. Graphs of spike frequency and spike amplitude versus burst intensity and duration are presented. So far, no evidence of grouping is seen.
