A self-consistent explanation of the MeV line in GRB 221009A unveils a dense circum-stellar medium
O. S. Salafia, A. Celotti, E. Sobacchi +6
GRB~221009A has been the brightest gamma-ray burst (GRB) observed to date, and its afterglow has been characterized with unprecedented detail at TeV energies by LHAASO. Quite puzzl…
Short GRBs at the dawn of the gravitational wave era
G. Ghirlanda, O. S. Salafia, A. Pescalli +16
We derive the luminosity function and redshift distribution of short Gamma Ray Bursts (SGRBs) using (i) all the available observer-frame constraints (i.e. peak flux, fluence, peak…
NuSTAR, Swift, and GROND observations of the flaring MeV blazar: PMN J06410320
M. Ajello, G. Ghisellini, V. S. Paliya +19
MeV blazars are a sub--population of the blazar family, exhibiting larger--than--average jet powers, accretion luminosities and black hole masses. Because of their extremely hard X…
The rate and luminosity function of long Gamma Ray Bursts
A. Pescalli, G. Ghirlanda, R. Salvaterra +7
We derive, adopting a direct method, the luminosity function and the formation rate of long Gamma Ray Bursts through a complete, flux-limited, sample of Swift bursts which has a hi…
A complete sample of bright Swift short Gamma-Ray Bursts
P. D'Avanzo, R. Salvaterra, M. G. Bernardini +10
We present a carefully selected sample of short gamma-ray bursts (SGRBs) observed by the Swift satellite up to June 2013. Inspired by the criteria we used to build a similar sample…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
