Bulk Lorentz factors of Gamma-Ray Bursts
G. Ghirlanda, F. Nappo, G. Ghisellini +6
Knowledge of the bulk Lorentz factor of GRBs allows us to compute their comoving frame properties shedding light on their physics. Upon collisions with the circumburst matt…
Jet-driven and jet-less fireballs from compact binary mergers
Om S. Salafia, Gabriele Ghisellini, Giancarlo Ghirlanda
During a compact binary merger involving at least one neutron star, a small fraction of the gravitational energy could be liberated in such a way to accelerate a small fraction (~…
Interpreting GRB170817A as a giant flare from a jet-less double neutron-star merger
Om S. Salafia, Gabriele Ghisellini, Giancarlo Ghirlanda +1
We show that the delay between GRB170817A and GW170817 is incompatible with de-beamed emission from an off-axis relativistic jet. The prompt emission and the subsequent radio and X…
Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Where and when: optimal scheduling of the electromagnetic follow-up of gravitational-wave events based on counterpart lightcurve models
Om S. Salafia, Monica Colpi, Marica Branchesi +4
The electromagnetic (EM) follow-up of a gravitational wave (GW) event requires to scan a wide sky region, defined by the so called "skymap", for the detection and identification of…
