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…
New results on the gamma-ray burst variability-luminosity relation
C. Guidorzi, R. Maccary, A. Tsvetkova +13
At the dawn of the gamma-ray burst (GRB) afterglow era, a Cepheid-like correlation was discovered between time variability V and isotropic-equivalent peak luminosity Liso of the pr…
A Short History of the First 50 Years: from the GRB Prompt Emission and Afterglow Discoveries to the Multimessenger Era
Filippo Frontera
More than fifty years have been elapsed from the first discovery of a Gamma Ray Burst (GRB) with the American Vela satellites, and more than twenty-five years from the discovery wi…
Long gamma-ray burst light curves as the result of a common stochastic pulse-avalanche process
Lorenzo Bazzanini, Lisa Ferro, Cristiano Guidorzi +9
Context. The complexity and variety exhibited by the light curves of long gamma-ray bursts (GRBs) enclose a wealth of information that still awaits being fully deciphered. Despite…
Recent developments in Laue lens manufacturing and their impact on imaging performance
Lisa Ferro, Enrico Virgilli, Natalia Auricchio +9
We report on recent progress in the development of Laue lenses for applications in hard X/soft gamma-ray astronomy. Here we focus on the realization of a sector of such a lens made…
Average power density spectrum of long GRBs detected with BeppoSAX/GRBM and with Fermi/GBM
S. Dichiara, C. Guidorzi, L. Amati +1
From past experiments the average power density spectrum (PDS) of GRBs with unknown redshift was found to be modelled from 0.01 to 1 Hz with a power-law, f^(-alpha), with alpha bro…
Extremely energetic Fermi Gamma-Ray Bursts obey spectral energy correlations
L. Amati, F. Frontera, C. Guidorzi
The extremely energetic Fermi GRBs 080916C, with its Eiso of ~ 10^{55} erg in 1 keV - 10 GeV and intense GeV emission, and 090323 give us a unique opportunity to test the reliabili…
