Fermi Constraints on the Ejecta Speed and Prompt Emission Region of the Distant GRB 220101A
At redshift z = 4.618, GRB 220101A is the most distant gamma-ray burst (GRB) detected by Fermi/LAT to date. It is also a very energetic event, with an equivalent isotropic energy of 3.6 × 10 ^54 erg. We jointly analyzed the Fermi/GBM and LAT observations of GRB 220101A with two independent approache...
