Highly-ionized metals as probes of the circumburst gas in the natal regions of gamma-ray bursts
K. E. Heintz, D. Watson, P. Jakobsson +18
We present here a survey of high-ionization absorption lines in the afterglow spectra of long-duration gamma-ray bursts (GRBs) obtained with the VLT/X-shooter spectrograph. Our mai…
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…
GRB 110715A: The peculiar multiwavelength evolution of the first afterglow detected by ALMA
R. Sánchez-Ramírez, P. J. Hancock, G. Jóhannesson +35
We present the extensive follow-up campaign on the afterglow of GRB 110715A at 17 different wavelengths, from X-ray to radio bands, starting 81 seconds after the burst and extendin…
The optical identifcation of events with poorly defined locations: The case of the Fermi GBM GRB140801A
V. M. Lipunov, J. Gorosabel, M. V. Pruzhinskaya +50
We report the early discovery of the optical afterglow of gamma-ray burst (GRB) 140801A in the 137 deg 3- error-box of the Fermi Gamma-ray Burst Monitor (GBM). MASTER is the…
GRB 120422A/SN 2012bz: Bridging the Gap between Low- And High-Luminosity GRBs
S. Schulze, D. Malesani, A. Cucchiara +62
At low redshift, a handful of gamma-ray bursts (GRBs) have been discovered with peak luminosities () substantially lower than the average…
The Metallicity of High- GRBs: the Case of GRB 111008A
Martin Sparre
With optical and near-infrared follow-up observations of gamma-ray bursts (GRBs) it is possible to study the chemical enrichment of galaxies at high redshift. Especially interestin…
