Fermi-LAT Detection of a GeV Afterglow from a Compact Stellar Merger
Fermi-LAT Detection of a GeV Afterglow from a Compact Stellar Merger
It is usually thought that the long-duration (>2 s) gamma-ray bursts (GRBs) are associated with massive star core collapse, however the short-duration (<2 s) GRBs are associated with mergers of compact stellar binaries. In this work, we report the Fermi-LAT detection of gamma-ray (> 100 MeV) afterglow emission from GRB …
