GRB 180728A and SN 2018fip: the nearest high-energy cosmological gamma-ray burst with an associated supernova

A. Rossi, L. Izzo, K. Maeda +29

The long GRB 180728A, at a redshift of $z=0.1171$, stands out due to its high isotropic energy of $E_{\gamma ,iso}\sim 2.5\times 10^{51}$ erg, in contrast with most events at redshif…
