A Comprehensive Analysis of Swift/XRT Data: III. Jet Break Candidates in X-ray and Optical Afterglow Lightcurves
En-Wei Liang, Judith L. Racusin, Bing Zhang +2
The Swift/XRT data of 179 GRBs (from 050124 to 070129) and the optical afterglow data of 57 pre- and post-Swift GRBs are analyzed, in order to systematically investigate the jet-li…
The First Survey of X-ray Flares from Gamma Ray Bursts Observed by Swift: Spectral Properties and Energetics
A. D. Falcone, D. Morris, J. Racusin +12
Observations of gamma ray bursts (GRBs) with Swift produced the initially surprising result that many bursts have large X-ray flares superimposed on the underlying afterglow. The f…
An online repository of Swift/XRT light curves of GRBs
P. A. Evans, A. P. Beardmore, K. L. Page +12
Context. Swift data are revolutionising our understanding of Gamma Ray Bursts. Since bursts fade rapidly, it is desirable to create and disseminate accurate light curves rapidly. A…
Chandra Observations of Supernova 1987A
Sangwook Park, David N. Burrows, Gordon P. Garmire +3
We have been monitoring Supernova (SN) 1987A with {\it Chandra X-Ray Observatory} since 1999. We present a review of previous results from our {\it Chandra} observations, and some…
The First Survey of X-ray Flares from Gamma Ray Bursts Observed by Swift: Temporal Properties and Morphology
G. Chincarini, A. Moretti, P. Romano +24
We present the first systematic investigation of the morphological and timing properties of flares in GRBs observed by Swift/XRT. We consider a large sample drawn from all GRBs det…
GRB 050822: Detailed analysis of an XRF observed by Swift
O. Godet, K. L. Page, J. Osborne +10
We report on the temporal and spectral characteristics of the early X-ray emission from the GRB 050822 as observed by Swift. This burst is likely to be an XRF showing major X-ray f…
