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…
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 potential of INTEGRAL for the detection of high redshift GRBs
J. Gorosabel, N. Lund, S. Brandt +3
We discuss INTEGRAL's capabilities to detect a high redshift population of Gamma-Ray Bursts (GRBs) in comparison to other high-energy missions. Emphasis is done on the study of the…
The supernova 2003lw associated with X-ray flash 031203
B. Thomsen, J. Hjorth, D. Watson +13
The X-Ray Flash (XRF), 031203 with a host galaxy at z=0.1055, is, apart from GRB980425, the closest Gamma-Ray Burst (GRB) or XRF known to date. We monitored its host galaxy from 1-…
Discovery and Evolution of an Unusual Luminous Variable Star in NGC 3432 (Supernova 2000ch)
R. M. Wagner, F. J. Vrba, A. A. Henden +15
We present photometric and spectroscopic observations of SN 2000ch, an unusual and extremely luminous variable star located in the galaxy NGC 3432. The object was discovered on 200…
