GRB 130606A within a sub-DLA at redshift 5.91
A. J. Castro-Tirado, R. Sánchez-Ramírez, S. L. Ellison +38
Events such as GRB130606A at z=5.91, offer an exciting new window into pre-galactic metal enrichment in these very high redshift host galaxies. We study the environment and host ga…
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…
The low-extinction afterglow in the solar-metallicity host galaxy of GRB 110918A
J. Elliott, T. Krühler, J. Greiner +21
Galaxies selected through long gamma-ray bursts (GRBs) could be of fundamental importance when mapping the star formation history out to the highest redshifts. Before using them as…
The low-extinction afterglow in the solar-metallicity host galaxy of gamma-ray burst 110918A
J. Elliott, T. Krühler, J. Greiner +21
Metallicity is theoretically thought to be a fundamental driver in gamma-ray burst (GRB) explosions and energetics, but is still, even after more than a decade of extensive studies…
GRB 081007 and GRB 090424: the surrounding medium, outflows and supernovae
Zhi-Ping Jin, Stefano Covino, Massimo Della Valle +34
We discuss the results of the analysis of multi-wavelength data for the afterglows of GRB 081007 and GRB 090424, two bursts detected by Swift. One of them, GRB 081007, also shows a…
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…
The optical counterpart of the bright X-ray transient Swift J1745-26
T. Muñoz-Darias, A. de Ugarte Postigo, D. M. Russell +13
We present a 30-day monitoring campaign of the optical counterpart of the bright X-ray transient Swift J1745-26, starting only 19 minutes after the discovery of the source. We obse…
