Investigating the Nature of Late-Time High-Energy GRB Emission Through Joint Fermi /Swift Observations
{{output}}
We use joint observations by the Neil Gehrels Swift X-ray Telescope (XRT) and the Fermi Large Area Telescope (LAT) of gamma-ray burst (GRB) afterglows to investigate the nature of the long-lived high-energy emission observed by Fermi LAT. Joint broadband spect... ...
