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…
HI column densities of z > 2 Swift gamma-ray bursts
P. Jakobsson, J. P. U. Fynbo, C. Ledoux +18
Context: Before the launch of the Swift satellite, the majority of the gamma-ray burst (GRB) afterglows for which Ly-alpha was redshifted into the observable spectrum showed eviden…
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…
No supernovae associated with two long-duration gamma ray bursts
Johan P. U. Fynbo, Darach Watson, Christina C. Thoene +28
It is now accepted that long duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard "collapsar" model predicts that a broad-lined and lum…
Microlensing variability in time-delay quasars
D. Paraficz, J. Hjorth, I. Burud +2
We have searched for microlensing variability in the light curves of five gravitationally lensed quasars with well-determined time delays: SBS 1520+530, FBQ 0951+2635, RX J0911+055…
Supernova 2006aj and the associated X-Ray Flash 060218
J. Sollerman, A. O. Jaunsen, J. P. U. Fynbo +23
We have studied the afterglow of the gamma-ray burst (GRB) of February 18, 2006. This is a nearby long GRB, with a very low peak energy, and is therefore classified as an X-ray Fla…
