A mean redshift of 2.8 for Swift gamma-ray bursts
P. Jakobsson, A. Levan, J. P. U. Fynbo +18
The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for exploration of the hi…
The host galaxy cluster of the short gamma-ray burst GRB 050509B
K. Pedersen, A. Eliasdottir, J. Hjorth +7
The first arcsecond localization of a short gamma-ray burst, GRB 050509B, has enabled detailed studies of a short burst environment. We here report on studies of the environment of…
A log N(HI) = 22.6 DLA in a dark gamma-ray burst: the environment of GRB 050401
D. Watson, J. P. U. Fynbo, C. Ledoux +33
The optical afterglow spectrum of GRB050401 (at z=2.8992+/-0.0004) shows the presence of a DLA, with log(nHI)=22.6+/-0.3. This is the highest column density ever observed in a DLA,…
On the Afterglow and Host Galaxy of GRB021004: A Comprehensive Study with the Hubble Space Telescope
J. P. U. Fynbo, J. Gorosabel, A. Smette +24
(Abridged) We report on HST observations of the late-time afterglow and host galaxy of GRB021004 (z=2.33). Although this GRB is one of the best observed so far, there is substantia…
