Colour variations in the GRB 120327A afterglow
A. Melandri, S. Covino, E. Zaninoni +42
We present a comprehensive temporal and spectral analysis of the long Swift GRB 120327A afterglow data to investigate the possible causes of the observed early time colour variatio…
Solving the conundrum of intervening strong MgII absorbers towards GRBs and quasars
L. Christensen, S. D. Vergani, S. Schulze +33
Previous studies have shown that the incidence rate of intervening strong MgII absorbers towards GRBs were a factor of 2 - 4 higher than towards quasars. Exploring the similar size…
A Molecular gas rich GRB host galaxy at the peak of cosmic star formation
M. Arabsalmani, E. Le Floc'h, H. Dannerbauer +10
We report the detection of the CO(3-2) emission line from the host galaxy of Gamma Ray Burst (GRB) 080207 at = 2.086. This is the first detection of molecular gas in emission f…
The host galaxy of the short GRB111117A at : impact on the short GRB redshift distribution and progenitor channels
J. Selsing, T. Krühler, D. Malesani +26
It is notoriously difficult to localize short -ray bursts (sGRBs) and their hosts to measure their redshifts. These measurements, however, are critical to constrain the nature o…
Polarimetry and Photometry of Gamma-Ray Bursts with RINGO2
I. A. Steele, D. Kopac, D. M. Arnold +8
We present a catalog of early-time (~10^2-10^4s) photometry and polarimetry of all Gamma-Ray Burst (GRB) optical afterglows observed with RINGO2 imaging polarimeter on the Liverpoo…
The chemical enrichment of long-GRB nurseries up to z=2
S. D. Vergani, J. Palmerio, R. Salvaterra +12
We investigate the existence of a metallicity threshold for the production of long gamma-ray bursts (LGRBs). We used the host galaxies of the Swift/BAT6 sample of LGRBs. We conside…
