The GROND gamma-ray burst sample. I. Overview and statistics
J. Greiner, T. Krühler, J. Bolmer +17
A dedicated gamma-ray burst (GRB) afterglow observing program was performed between 2007 and 2016 with GROND, a seven-channel optical and near-infrared imager at the 2.2m telescope…
The VISTA ZYJHKs Photometric System: Calibration from 2MASS
Carlos González-Fernández, Simon T. Hodgkin, Michael J. Irwin +7
In this paper we describe the routine photometric calibration of data taken with the VIRCAM instrument on the ESO VISTA telescope. The broadband ZYJHKs data are directly calibrated…
A quiescent galaxy at the position of the long GRB 050219A
A. Rossi, S. Piranomonte, S. Savaglio +25
Long-duration gamma-ray bursts (LGRBs) are produced by the collapse of very massive stars. Due to the short lifetime of their progenitors, LGRBs pinpoint star-forming galaxies. We…
GRB 090426: Discovery of a jet break in a short burst afterglow
A. Nicuesa Guelbenzu, S. Klose, A. Rossi +14
Context: The link between the duration of GRBs and the nature of their progenitors remains disputed. Short bursts (with durations of less than ~2 s) are less frequently observed, t…
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
T. Krühler, P. Schady, J. Greiner +18
We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for fi…
Discovery of the Near-IR Afterglow and of the Host of GRB 030528
A. Rau, J. Greiner, S. Klose +24
The rapid dissemination of an arcmin-sized HETE-2 localization of the long-duration X-ray flash GRB 030528 led to a ground-based multi-observatory follow-up campaign. We report the…
