The GRB 030329 host: a blue low metallicity subluminous galaxy with intense star formation

J. Gorosabel, D. Pérez-Ramírez, J. Sollerman +13

We present broad band photometry and spectroscopic observations of the host galaxy of GRB 030329. Analysis of the spectral emission lines shows that the host is likely a low metall…

Swift Identification of Dark Gamma-Ray Bursts

P. Jakobsson, J. Hjorth, J. P. U. Fynbo +4

We present an optical flux vs. X-ray flux diagram for all known gamma-ray bursts (GRBs) for which an X-ray afterglow has been detected. We propose an operational definition of dark…

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 Afterglow of GRB010222: A Case of Continuous Energy Injection

G. Bjornsson, J. Hjorth, K. Pedersen +1

The optical lightcurve of GRB010222 exhibited one of the slowest decays of any gamma-ray burst to date. Its broadband properties have been difficult to explain with conventional af…

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 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…
