Gamma-ray bursts (GRBs) have puzzled astronomers since their accidental discovery in the
late 1960s. The BATSE detector on the COMPTON-GRO satellite has been detecting one …

▪ Abstract The discovery of counterparts in X-ray and optical to radio wavelengths has
revolutionized the study of γ-ray bursts, until recently the most enigmatic of astrophysical …

The discovery of afterglows associated with γ-ray bursts at X-ray, optical and radio
wavelengths and the measurement of the redshifts of some of these events, has established …

We present a comprehensive study to measure the locations of gamma-ray bursts (GRBs)
relative to their host galaxies. In total, we find the offsets of 20 long-duration GRBs from their …

We present a sample of 77 optical afterglows (OAs) of Swift detected gamma-ray bursts
(GRBs) for which spectroscopic follow-up observations have been secured. Our first …

We present data and initial results from VLT/X-Shooter emission-line spectroscopy of 96
galaxies selected by long γ-ray bursts (GRBs) at 0.1< z< 3.6, the largest sample of GRB host …

Context. Thirteen years after the discovery of the first afterglows, the nature of dark gamma-
ray bursts (GRB) still eludes explanation: while each long-duration GRB typically has an X …

We present observations and analysis of the host galaxies of 23 heavily dust-obscured
gamma-ray bursts (GRBs) observed by the Swift satellite during the years 2005–2009 …

ABSTRACT We introduce the Swift Gamma-Ray Burst Host Galaxy Legacy Survey ("
SHOALS"), a multi-observatory high-redshift galaxy survey targeting the largest unbiased …

We present optical and near-infrared photometry of the afterglow of the long gamma-ray
burst (GRB) 070802 at redshift 2.45 obtained with the ESO/MPI 2.2 m telescope equipped …
