A decade of Gamma-Ray Bursts observed by $Fermi$-LAT: The 2$^{nd}$ GRB catalog

Understand

The Large Area Telescope (LAT) aboard the $Fermi$ spacecraft routinely observes high-energy emission from gamma-ray bursts (GRBs).

• Here we present the second catalog of LAT-detected GRBs, covering the first 10 years of operations, from 2008 August 4 to 2018 August 4.
• A total of 186 GRBs are found; of these, 91 show emission in the range $30-100\,$MeV (17 of which are seen only in this band) and 169 are detected above 100 MeV.
• Most of these sources were discovered by other instruments ($Fermi$/GBM, $Swift$/BAT, AGILE, INTEGRAL) or reported by the Interplanetary Network (IPN); the LAT has independently triggered on 4 GRBs.
