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…
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…
Probing Cosmic Chemical Evolution with Gamma-Ray Bursts: GRB060206 at z=4.048
J. P. U. Fynbo, R. L. C. Starling, C. Ledoux +25
Aim: We present early optical spectroscopy of the afterglow of the gamma-ray burst GRB 060206 with the aim of determining the metallicity of the GRB absorber and the physical condi…
