The nature of "dark" gamma-ray bursts
J. Greiner, T. Krühler, S. Klose +11
Context: Thirteen years after the discovery of the first afterglows, the nature of dark gamma-ray bursts (GRB) still eludes explanation: while each ng-duration GRB typically has an…
The missing gas problem in GRB host galaxies: evidence for a highly ionised component
P. Schady, S. Savaglio, T. Kruehler +2
There is considerable discrepancy between the amount of X-ray absorption and that inferred from optical (rest frame UV) as measured along gamma-ray burst (GRB) sight lines, with th…
The Swift/Fermi GRB 080928 from 1 eV to 150 keV
A. Rossi, S. Schulze, S. Klose +28
We present the results of a comprehensive study of the gamma-ray burst 080928 and of its afterglow. GRB 080928 was a long burst detected by Swift/BAT and Fermi/GBM. It is one of th…
Highly Extinguished Host Galaxy of the Dark GRB 020819
A. Küpcü Yoldaş, J. Greiner, S. Klose +2
We analyse the properties of the host galaxy of the optically dark gamma-ray burst (GRB) 020819 (z = 0.41) and discuss the possible implications in the context of "dark" GRBs. We p…
A very metal poor Damped Lyman-alpha system revealed through the most energetic GRB 090926A
Arne Rau, S. Savaglio, T. Krühler +9
We present VLT/FORS2 spectroscopy and GROND optical/near-IR photometry of the afterglow of the bright Fermi/LAT GRB 090926A. The spectrum shows prominent Lyman-alpha absorption wit…
GRB 081008: from burst to afterglow and the transition phase in between
F. Yuan, P. Schady, J. L. Racusin +30
We present a multi-wavelength study of GRB 081008, at redshift 1.967, by Swift, ROTSE-III and GROND. Compared to other Swift GRBs, GRB 081008 has a typical gamma-ray isotropic equi…
Evidence for Supernova-Synthesised Dust from the Rising Afterglow of GRB 071025 at z~5
Daniel A. Perley, J. S. Bloom, C. R. Klein +21
We present observations and analysis of the broadband afterglow of Swift GRB 071025. Using optical and infrared (RIYJHK) photometry, we derive a photometric redshift of 4.4 < z < 5…
