GRB X-ray plateaus as evidence that the afterglow begins before the prompt gamma-ray emission
C. Guidorzi, R. Maccary, M. Maistrello +3
Most GRB X-ray afterglow light curves are characterised by a plateau, followed by a normal power-law decay interpreted as afterglow emission. Despite the numerous alternative inter…
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…
Gamma-ray burst taxonomy: looking for the third class on the spectral peak energy-duration plane in the rest frame
Anastasia Tsvetkova, Lorenzo Amati, Mattia Bulla +8
Two classes of Gamma-ray bursts (GRBs), corresponding to the short/hard and the long/soft events, with a putative intermediate class, are typically considered in the observer frame…
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…
