An origin for short g-ray bursts unassociated with current star formation
S. D. Barthelmy, G. Chincarini, D. N. Burrows +28
Two short (<2 s) g-ray bursts (GRBs) have recently been localized and fading afterglow counterparts detected. The combination of these two results left unclear the nature of the ho…
The dust-scattered X-ray halo around Swift GRB 050724
S. Vaughan, R. Willingale, P. Romano +12
This paper discusses the X-ray halo around the Swift gamma-ray burst GRB 050724 (z=0.258), detected by the Swift X-Ray Telescope. The halo, which forms a ring around the fading X-r…
XRT Light curves: Morphology, Flares and Energy
G. Chincarini, V. Mangano, A. Moretti +10
Following a brief introduction we show that the observations obtained so far with the Swift satellite begin to shed light over a variety of problems that were left open following t…
A refined position catalog of the Swift XRT afterglows
A. Moretti, M. Perri, M. Capalbi +22
We present 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. This is a result o…
Swift XRT Observations of X-ray Flares in GRB Afterglows
David N. Burrows, P. Romano, O. Godet +18
The Swift XRT has been observing GRB afterglows since December 23, 2004. Three-quarters of these observations begin within 300 s of the burst onset, providing an unprecendented loo…
The in-flight spectroscopic performance of the Swift XRT CCD camera
J. P. Osborne, A. P. Beardmore, O. Godet +23
The Swift X-ray Telescope (XRT) focal plane camera is a front-illuminated MOS CCD, providing a spectral response kernel of 144 eV FWHM at 6.5 keV. We describe the CCD calibration p…
