The most distant optically polarised GRB afterglow: GRB 240419A at z = 5.178
R. Brivio, S. Covino, M. Ferro +31
Gamma-ray bursts (GRBs) are extremely bright phenomena powered by relativistic jets arising from explosive events at cosmological distances. The nature of the jet and the configura…
The BlackGEM telescope array I: Overview
Paul J. Groot, S. Bloemen, P. Vreeswijk +75
The main science aim of the BlackGEM array is to detect optical counterparts to gravitational wave mergers. Additionally, the array will perform a set of synoptic surveys to detect…
Time-dependent excitation and ionization modelling of absorption-line variability due to GRB 080310
P. M. Vreeswijk, C. Ledoux, A. J. J. Raassen +6
We model the time-variable absorption of FeII, FeIII, SiII, CII and CrII detected in UVES spectra of GRB 080310, with the afterglow radiation exciting and ionizing the interstellar…
VLT/X-shooter spectroscopy of the GRB 090926A afterglow
V. D'Elia, J. P. U. Fynbo, S. Covino +21
The aim of this paper is to study the environment and intervening absorbers of the gamma-ray burst GRB 090926A through analysis of optical spectra of its afterglow. We analyze medi…
Low-Resolution Spectroscopy of Gamma-ray Burst Optical Afterglows: Biases in the Swift Sample and Characterization of the Absorbers
J. P. U. Fynbo, P. Jakobsson, J. X. Prochaska +39
(Abridged). We present a sample of 77 optical afterglows (OAs) of Swift detected GRBs for which spectroscopic follow-up observations have been secured. We provide linelists and equ…
Very high column density and small reddening towards GRB 020124 at z = 3.20
J. Hjorth, P. Møller, J. Gorosabel +27
We present optical and near-infrared observations of the dim afterglow of GRB 020124, obtained between 2 and 68 hours after the gamma-ray burst. The burst occurred in a very faint…
