Contributed Gamma-ray Bursts Exploring the Cosmos: GRB-1


Dr Andreas von Kienlin (MPE)


With the completion of the first decade of operation, Fermi-GBM has been longer in orbit than its predecessor experiment BATSE on-board CGRO. It is capable to detect almost the same number of GRBs (~240 GBM GRBs compared ~300 BATSE GRBs per year) resulting in 2357 triggers on cosmic GRBs during the first ten years. The GBM GRB catalog series is now continued by the latest releases of the GBM Gamma-Ray Burst and Spectral Catalogs. They summarize the basic characteristics of the triggered GRBs, like sky location, duration, peak flux, fluences and spectral properties. The statistical analyses of these quantities of the entire ten year GRB sample will be presented.

Furthermore the relevance of the GBM data for multi-messenger astrophysics is emphasized by presenting a search for GRBs with characteristics similar to GRB 170817A, conducted for the full time period of the current GBM GRB catalog. A total of 13 candidates were identified from which it is predicted that Fermi-GBM will trigger on-board on about one burst similar to GRB 170817A per year.
