TL;DR: In this article, the authors report the results of the analysis of the Swift X-ray Telescope Point Spread Function (PSF) as measured in the first four months of the mission during the instrument calibration phase.

TL;DR: In this article, a catalogue of refined positions of 68 gamma ray burst (GRB) afterglows observed by the Swift X-ray Telescope (XRT) from the launch up to 2005 Oct 16 is presented.
Journal ArticleDOI
X-ray flares in early GRB afterglows.
David N. Burrows,A. D. Falcone,G. Chincarini,G. Chincarini,D. C. Morris,P. Romano,Joanne E. Hill,Joanne E. Hill,Olivier Godet,Alberto Moretti,Hans A. Krimm,J. P. Osborne,Judith Racusin,V. Mangano,K. L. Page,M. Perri,Michael C. Stroh +16 more
TL;DR: The most likely cause of flares in early X-ray afterglows of gamma-ray bursts is late-time activity of the GRB central engine, but at lower photon energies.
Journal ArticleDOI
The prompt to late-time multiwavelength analysis of GRB 060210
P. A. Curran,A. J. van der Horst,Andrew P. Beardmore,K. L. Page,Evert Rol,A. Melandri,Ian A. Steele,Carole Mundell,A. Gomboc,P. T. O'Brien,D. Bersier,Michael F. Bode,David Carter,C. Guidorzi,C. Guidorzi,Joanne E. Hill,Cheryl Hurkett,Shiho Kobayashi,A. Monfardini,A. Monfardini,C. J. Mottram,Robert J. Smith,Ralph A. M. J. Wijers,Richard Willingale +23 more
TL;DR: It is found that the flaring gamma-ray and X-ray emission is likely due to internal shocks while the flat optical light curve at that time is due to the external shock.
Journal ArticleDOI
X-ray Flares in Early GRB Afterglows
David N. Burrows,A. D. Falcone,G. Chincarini,Derek W. Morris,P. Romano,Joanne E. Hill,O. Godet,A. Moretti,H. A. Krimm,J. P. Osborne,J. L. Racusin,V. Mangano,K. L. Page,M. Perri,Michael C. Stroh +14 more
TL;DR: In this article, the Swift X-ray Telescope (XRT) was used to detect gamma-ray afterglows of Gamma-Ray Bursts (GRBs), and the most likely cause of these flares was late-time activity of the GRB central engine.
