GRB minimum variability timescales with Fermi/GBM
R. Maccary, C. Guidorzi, A. E. Camisasca +8
Context. Gamma-ray bursts (GRBs) have traditionally been classified by duration into long (LGRBs) and short (SGRBs), with the former believed to originate from massive star collaps…

A search for periodic activity in multi-peaked long gamma-ray bursts
C. Guidorzi, M. Orlandini, R. Maccary +10
A sizeable fraction of gamma-ray burst (GRB) light curves (LCs) features a sequence of peaks, which holds information on the unknown way energy is dissipated into gamma-rays over t…

An advanced pulse-avalanche stochastic model of long gamma-ray burst light curves
Manuele Maistrello, Lisa Ferro, Lorenzo Bazzanini +2
A unified explanation of the variety of long-duration gamma-ray burst (GRB) light curves (LCs) is essential for identifying the dissipation mechanism and possibly the nature of the…
