Comparing the spectral lag of short and long gamma-ray bursts and its relation with the luminosity
M. G. Bernardini, G. Ghirlanda, S. Campana +14
We investigated the rest frame spectral lags of two complete samples of bright long (50) and short (6) gamma-ray bursts (GRB) detected by Swift. We analysed the Swift/BAT data thro…
Circular polarization in the optical afterglow of GRB 121024A
K. Wiersema, S. Covino, K. Toma +37
Gamma-ray bursts (GRBs) are most probably powered by collimated relativistic outflows (jets) from accreting black holes at cosmological distances. Bright afterglows are produced wh…
The mysterious optical afterglow spectrum of GRB140506A at z=0.889
J. P. U. Fynbo, T. Krühler, K. Leighly +40
Context. Gamma-ray burst (GRBs) afterglows probe sightlines to star-forming regions in distant star-forming galaxies. Here we present a study of the peculiar afterglow spectrum of…
Are LGRBs biased tracers of star formation? Clues from the host galaxies of the Swift/BAT6 complete sample of LGRBs. I: Stellar mass at z<1
S. D. Vergani, R. Salvaterra, J. Japelj +20
LGRBs are associated with massive stars and are therefore linked to star formation. The conditions necessary to produce LGRBs can affect the relation between the LGRB rate and star…
The warm, the excited, and the molecular gas: GRB 121024A shining through its star-forming galaxy
M. Friis, A. De Cia, T. Krühler +28
We present the first reported case of the simultaneous metallicity determination of a gamma-ray burst (GRB) host galaxy, from both afterglow absorption lines as well as strong emis…
VLT/X-shooter spectroscopy of the afterglow of the Swift GRB 130606A: Chemical abundances and reionisation at
O. E. Hartoog, D. Malesani, J. P. U. Fynbo +28
The reionisation of the Universe is thought to have ended around z~6, as inferred from spectroscopy of distant bright background sources, such as quasars (QSO) and gamma-ray burst…
