GRB 030227: the first multiwavelength afterglow of an INTEGRAL GRB
A. J. Castro-Tirado, J. Gorosabel, S. Guziy +39
We present multiwavelength observations of a gamma-ray burst detected by INTEGRAL (GRB 030227) between 5.3 hours and ~1.7 days after the event. Here we report the discovery of a di…
The Host Galaxy of GRB 990712
Lise Christensen, Jens Hjorth, Javier Gorosabel +4
We present a comprehensive study of the z=0.43 host galaxy of GRB 990712, involving ground-based photometry, spectroscopy, and HST imaging. The broad-band UBVRIJHKs photometry is u…
New search strategy for high z intervening absorbers: GRB021004, a pilot study
P. M. Vreeswijk, P. Moller, J. P. U. Fynbo
We present near-infrared narrow- and broad-band imaging of the field of GRB021004, performed with ISAAC on the UT1 of the ESO Very Large Telescope. The narrow-band filters were cho…
The blue host galaxy of the red GRB 000418
J. Gorosabel, S. Klose, L. Christensen +25
We report on multi-band (UBVRIZJsKs) observations of the host galaxy of the April 18, 2000 gamma-ray burst. The Spectral Energy Distribution (SED) is analysed by fitting empirical…
Variable polarization in the optical afterglow of GRB 021004
E. Rol, R. A. M. J. Wijers, J. P. U. Fynbo +19
We present polarimetric observations of the afterglow of gamma-ray burst (GRB) 021004, obtained with the Nordic Optical Telescope (NOT) and the Very Large Telescope (VLT) between 8…
Optical and near-infrared observations of the GRB020405 afterglow
N. Masetti, E. Palazzi, E. Pian +33
(Abridged) We report on observations of the optical and NIR afterglow of GRB020405. Ground-based optical observations started about 1 day after the GRB and spanned a period of ~10…
