The line-of-sight towards GRB 030429 at z = 2.66: Probing the matter at stellar, galactic and intergalactic scales
P. Jakobsson, J. Hjorth, J. P. U. Fynbo +21
We report the discovery of the optical afterglow (OA) of the long-duration gamma-ray burst GRB 030429, and present a comprehensive optical/near-infrared dataset used to probe the m…
The supernova 2003lw associated with X-ray flash 031203
B. Thomsen, J. Hjorth, D. Watson +13
The X-Ray Flash (XRF), 031203 with a host galaxy at z=0.1055, is, apart from GRB980425, the closest Gamma-Ray Burst (GRB) or XRF known to date. We monitored its host galaxy from 1-…
On the Afterglow of the X-Ray Flash of July 23 2003: Photometric evidence for an off-axis Gamma-Ray Burst with an associated Supernova?
J. P. U. Fynbo, J. Sollerman, J. Hjorth +31
We present optical and near-infrared follow-up observations of the X-Ray Flash (XRF) of July 23 2003. Our observations in the R-band cover the temporal range from 4.2 h to 64 days…
The host of GRB 030323 at z=3.372: a very high column density DLA system with a low metallicity
P. M. Vreeswijk, S. L. Ellison, C. Ledoux +29
We present photometry and spectroscopy of the afterglow of GRB 030323. VLT spectra of the afterglow show damped Lya (DLA) absorption and low- and high-ionization lines at a redshif…
The GRB-SN connection: GRB030329 and XRF030723
J. P. U. Fynbo, J. Hjorth, J. Sollerman +11
The attempt to secure conclusive, spectroscopic evidence for the GRB/SN connection has been a central theme in most GRB observing time proposals since the discovery of the very unu…
Small-scale variations in the radiating surface of the GRB 011211 jet
P. Jakobsson, J. Hjorth, E. Ramirez-Ruiz +12
We report the discovery of the afterglow of the X-ray rich, long-duration gamma-ray burst GRB 011211 and present evidence for oscillatory behaviour in its early optical light curve…
