GRB Fermi-LAT afterglows: explaining flares, breaks, and energetic photons
N. Fraija, T. Laskar, S. Dichiara +4
The Fermi-LAT collaboration presented the second gamma-ray burst (GRB) catalog covering its first 10 years of operations. A significant fraction of afterglow-phase light curves in…
Afterglow light curves of the non-relativistic ejecta mass in a stratified circumstellar medium
N. Fraija, B. Betancourt Kamenetskaia, M. G. Dainotti +4
We present the afterglow light curves produced by the deceleration of the non-relativistic ejecta mass in a stratified circumstellar medium with a density profile $n(r)\propto r^{-…
On the origin of the multi-GeV photons from the closest burst with intermediate luminosity: GRB 190829A
N. Fraija, P. Veres, P. Beniamini +4
Very-high-energy (VHE) emission is usually interpreted in the synchrotron-self Compton (SSC) scenario, and expected from the low-redshift and high-luminosity gamma-ray bursts (GRBs…
Ready, set, launch: time interval between BNS merger and short GRB jet formation
Paz Beniamini, Rodolfo Barniol Duran, Maria Petropoulou +1
The joint detection of GW~170817/GRB 170817 confirmed the long-standing theory that binary neutron star mergers produce short gamma-ray burst (sGRB) jets that can successfully brea…
