Extensive multiband study of the X-ray rich GRB 050408. A likely off-axis event with an intense energy injection
A de Ugarte Postigo, T. A. Fatkhullin, G. Johannesson +40
Aims. Understand the shape and implications of the multiband light curve of GRB 050408, an X-ray rich (XRR) burst. Methods. We present a multiband optical light curve, covering the…
Fundamental Properties of GRB-Selected Galaxies: A Swift/VLT Legacy Survey
P. Jakobsson, J. Hjorth, J. P. U. Fynbo +2
We present the motivation, aims and preliminary result from the Swift/VLT legacy survey on gamma-ray burst host galaxies. This survey will produce a homogeneous and well-understood…
X-ray Flashes or soft Gamma-ray Bursts? The case of the likely distant XRF 040912
G. Stratta, S. Basa, N. Butler +49
In this work, we present a multi-wavelength study of XRF 040912, aimed at measuring its distance scale and the intrinsic burst properties. We performed a detailed spectral and temp…
Constraints on an optical afterglow and on supernova light following the short burst GRB 050813
P. Ferrero, S. F. Sanchez, D. A. Kann +18
We report early follow-up observations of the error box of the short burst 050813 using the telescopes at Calar Alto and at Observatorio Sierra Nevada (OSN), followed by deep VLT/F…
Detection of optical linear polarization in the SN2006aj/XRF060218 non-spherical expansion
J. Gorosabel, V. Larionov, A. J. Castro-Tirado +10
We have performed optical polarimetric observations of the SN2006aj associated to the X-ray flash (XRF) of February 18, 2006, XRF060218 that provide information on its expansion ge…
GRB 051028: an intrinsically faint GRB at high redshift?
A. J. Castro-Tirado, M. Jelinek, S. B. Pandey +16
We present multiwavelength observations of the gamma-ray burst GRB 051028 detected by HETE-2 in order to derive its afterglow emission parameters and to determine the reason for it…
