The metallicity and dust content of a redshift 5 gamma-ray burst host galaxy
M. Sparre, O. E. Hartoog, T. Krühler +26
Observations of the afterglows of long gamma-ray bursts (GRBs) allow the study of star-forming galaxies across most of cosmic history. Here we present observations of GRB 111008A f…
Molecular Hydrogen in the Damped Lyman-alpha System towards GRB 120815A at z=2.36
T. Krühler, C. Ledoux, J. P. U. Fynbo +32
We present the discovery of molecular hydrogen (H_2), including the presence of vibrationally-excited H_2^* in the optical spectrum of the afterglow of GRB 120815A at z=2.36 obtain…
Pre-ALMA observations of GRBs in the mm/submm range
A. de Ugarte Postigo, A. Lundgren, S. Martín +24
GRBs generate an afterglow emission that can be detected from radio to X-rays during days, or even weeks after the initial explosion. The peak of this emission crosses the mm/submm…
