The Fermi Gamma-ray Burst Monitor: Results from the first two years

TL;DR

The Fermi GBM has detected over 500 gamma-ray bursts and various transients in its first two years, providing valuable data for high-energy astrophysics research.

Contribution

This paper reports the first two years of scientific results from the Fermi GBM, including detection statistics and source types, highlighting its contributions to gamma-ray astronomy.

Findings

Detected over 500 GRBs in two years

18 GRBs were observed by LAT above 100 MeV

GBM also detected SGRs, TGFs, and solar flares

Abstract

In the first two years since the launch of the Fermi Observatory, the Gamma-ray Burst Monitor (GBM) has detected over 500 Gamma-Ray Bursts (GRBs), of which 18 were confidently detected by the Large Area Telescope (LAT) above 100 MeV. Besides GRBs, GBM has triggered on other transient sources, such as Soft Gamma Repeaters (SGRs), Terrestrial Gamma-ray Flashes (TGFs) and solar flares. Here we present the science highlights of the GBM observations.
