A universal GRB photon energy-peak luminosity relation
R. Willingale, P. T. O'Brien, M. R. Goad +3
The energetics and emission mechanism of GRBs are not well understood. Here we demonstrate that the instantaneous peak flux or equivalent isotropic peak luminosity, L_iso ergs s^-1…
Using Swift observations of prompt and afterglow emission to classify GRBs
P. T. O'Brien, R. Willingale
We present an analysis of early BAT and XRT data for 107 gamma--ray bursts (GRBs) observed by the Swift satellite. We use these data to examine the behaviour of the X-ray light cur…
An Update on the X-ray transient Narrow-Line Seyfert 1 galaxy WPVS 007: Swift observations of UV variability and persistence of X-ray faintness
Dirk Grupe, Patricia Schady, Karen M. Leighly +3
We report on the detection of UV variability and the persistence of X-ray faintness of the X-ray transient Narrow-Line Seyfert 1 galaxy WPVS 007 based on the first year of monitori…
The soft X-ray blast in the apparently sub-luminous GRB 031203
D. Watson, S. A. Vaughan, R. Willingale +11
GRB031203 was a very low apparent luminosity gamma-ray burst (GRB). It was also the first GRB with a dust-scattered X-ray halo. The observation of the halo allowed us to infer the…
Prompt and afterglow early X-ray phases in the comoving frame. Evidence for Universal properties?
G. Chincarini, A. Moretti, P. Romano +38
We analyze the Swift XRT light curves and spectra of the gamma-ray bursts (GRBs) for which the redshift has been measured. The sample consists of seven GRBs. The soft X-ray light c…
Gamma-Ray Bursts observed by XMM-Newton
P. T. O'Brien, J. N. Reeves, D. Watson +2
Analysis of observations with XMM-Newton have made a significant contribution to the study of Gamma-ray Burst (GRB) X-ray afterglows. The effective area, bandpass and resolution of…
