Dust Extinction in High-z Galaxies with GRB Afterglow Spectroscopy - The 2175Å Feature at z=2.45
Á. Elíasdóttir, J. P. U. Fynbo, J. Hjorth +8
We report the clear detection of the 2175A dust absorption feature in the optical afterglow spectrum of the gamma-ray burst (GRB) GRB070802 at a redshift of z=2.45. This is the hig…
Gamma-ray burst host galaxies and the link to star-formation
J. P. U. Fynbo, J. Hjorth, D. Malesani +5
We briefly review the current status of the study of long-duration gamma-ray burst (GRB) host galaxies. GRB host galaxies are mainly interesting to study for two reasons: 1) they m…
Achromatic Breaks for Swift GRBs: Any Evidence?
S. Covino, D. Malesani, G. Tagliaferri +5
The availability of multi-wavelength high-quality data of gamma-ray burst afterglows in the Swift era, contrary to the expectations, did not allow us to fully confirm yet one of th…
The multiwavelength afterglow of GRB 050721: a puzzling rebrightening seen in the optical but not in the X-ray
L. A. Antonelli, V. Testa, P. Romano +27
Context. GRB050721 was detected by Swift and promptly followed-up, in the X-ray by Swift itself and, in the optical band, by the VLT operated, for the first time, in rapid response…
Open issues in gamma-ray bursts: polarimetry and dark GRBs
D. Malesani, S. Covino, E. M. Rossi +4
We review some open problems in the physics of afterglows, namely their polarization properties and the existence of dark/faint bursts. Polarization studies yield precious insights…
