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…
Massive star-formation rates of gamma-ray burst host galaxies: an unobscured view in X-rays
D. Watson, J. Hjorth, P. Jakobsson +3
The hard X-ray (2-10keV) luminosity of a star-forming galaxy tracks its population of high mass X-ray binaries and is essentially unobscured. It is therefore a practically unbiased…
An optical time delay for the double gravitational lens system FBQ 0951+2635
P. Jakobsson, J. Hjorth, I. Burud +3
We present optical R-band light curves of the double gravitationally lensed quasar FBQ 0951+2635 from observations obtained at the Nordic Optical Telescope between March 1999 and J…
UV star-formation rates of GRB host galaxies
L. Christensen, J. Hjorth, J. Gorosabel
We study a magnitude-limited sample of 10 gamma-ray burst (GRB) host galaxies with known spectroscopic redshifts (0.43 < z < 2.04). From an analysis of the spectral energy distribu…
Supernova light curve models for the bump in the Optical Counterpart of X-Ray Flash 030723
N. Tominaga, J. Deng, P. A. Mazzali +5
XRF 030723 is the first X-ray flash (XRF) to show in its optical light curve (LC) a bump that has been interpreted as the signature of a supernova (SN). After subtracting the after…
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…
