Multi-Wavelength Studies of the Optically Dark Gamma-Ray Burst 001025A
K. Pedersen, K. Hurley, J. Hjorth +18
We identify the fading X-ray afterglow of GRB 001025A from XMM-Newton observations obtained 1.9-2.3 days, 2 years, and 2.5 years after the burst. The non-detection of an optical co…
GRB 040403: a faint X-ray rich Gamma-ray Burst discovered by INTEGRAL
S. Mereghetti, D. Gotz, M. I. Andersen +13
GRB 040403 is one of the faintest gamma-ray bursts for which a rapid and accurate localization has been obtained. Here we report on the gamma-ray properties of this burst, based on…
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…
The optical/near-IR spectral energy distribution of the GRB 000210 host galaxy
J. Gorosabel, L. Christensen, J. Hjorth +25
We report on UBVRIZJsHKs-band photometry of the dark GRB 000210 host galaxy. Fitting a grid of spectral templates to its Spectral Energy Distribution (SED), we derived a photometri…
The afterglow and complex environment of the optically dim burst GRB 980613
Jens Hjorth, Bjarne Thomsen, Svend R. Nielsen +15
We report the identification of the optical afterglow of GRB 980613 in R- and I-band images obtained between 16 and 48 hours after the gamma-ray burst. Early near-infrared (NIR) H…
The time delay of the quadruple quasar RX J0911.4+0551
Jens Hjorth, Ingunn Burud, Andreas O. Jaunsen +9
We present optical lightcurves of the gravitationally lensed components A (=A1+A2+A3) and B of the quadruple quasar RX J0911.4+0551 (z = 2.80). The observations were primarily obta…
