The early and late-time spectral and temporal evolution of GRB 050716
E. Rol, J. P. Osborne, K. L. Page +13
We report on a comprehensive set of observations of Gamma Ray Burst 050716, detected by the Swift satellite and subsequently followed-up rapidly in X-ray, optical and near infra-re…
Rapid-Response Mode VLT/UVES spectroscopy of GRB060418: Conclusive evidence for UV pumping from the time evolution of FeII and NiII excited- and metastable-level populations
P. M. Vreeswijk, C. Ledoux, A. Smette +11
We present high-resolution spectroscopic observations of GRB060418, obtained with VLT/UVES. These observations were triggered using the VLT Rapid Response Mode (RRM), which allows…
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…
Infrared and Optical Observations of GRB 030115 and its Extremely Red Host Galaxy: Implications for Dark Bursts
Andrew Levan, Andrew Fruchter, James Rhoads +24
We present near-infrared (nIR) and optical observations of the afterglow of GRB 030115. Discovered in an infrared search at Kitt Peak 5 hours after the burst trigger, this afterglo…
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…
The first Swift X-ray Flash: The faint afterglow of XRF 050215B
A. J. Levan, J. P. Osborne, N. R. Tanvir +17
We present the discovery of XRF 050215B and its afterglow. The burst was detected by the Swift BAT during the check-out phase and observations with the X-ray telescope began approx…
