The Jet and the Supernova in GRB990712
G. Bjornsson, J. Hjorth, P. Jakobsson +2
The optical light curve of the afterglow following the gamma-ray burst GRB990712 is re-examined. Recently published polarization measurements of that source require a collimated ou…
The Host Galaxy and Optical Light Curve of the Gamma-Ray Burst GRB 980703
S. Holland, J. P. U. Fynbo, J. Hjorth +10
We present deep HST/STIS and ground-based photometry of the host galaxy of the gamma-ray burst GRB 980703 taken 17, 551, 710, and 716 days after the burst. We find that the host is…
The optical afterglow and host galaxy of GRB000926
J. U. Fynbo, J. Gorosabel, T. H. Dall +27
We present the discovery of the Optical Transient (OT) of the long-duration gamma-ray burst GRB000926. The optical transient was detected independently with the Nordic Optical Tele…
HST/STIS Imaging of the Host Galaxy of GRB980425/SN1998bw
J. U. Fynbo, S. Holland, M. I. Andersen +6
We present HST/STIS observations of ESO 184-G82, the host galaxy of the gamma-ray burst GRB 980425 associated with the peculiar Type Ic supernova SN1998bw. ESO 184-G82 is found to…
The afterglow of the short/intermediate-duration gamma-ray burst GRB 000301C: A jet at z=2.04
B. L. Jensen, J. U. Fynbo, J. Gorosabel +23
We present Ulysses and NEAR data from the detection of the short or intermediate duration (2 s) gamma-ray burst GRB000301C (2000 March 1.41 UT). The gamma-ray burst (GRB) was local…
The late afterglow and host galaxy of GRB 990712
Jens Hjorth, Stephen Holland, Frederic Courbin +3
We present deep HST imaging, as well as ground-based imaging and spectroscopy, of the optical afterglow associated with the long-duration gamma-ray burst GRB 990712 and its host ga…
