The Giant X-ray Flare of GRB 050502B: Evidence for Late-Time Internal Engine Activity
A. D. Falcone, D. N. Burrows, D. Lazzati +28
Until recently, X-ray flares during the afterglow of gamma ray bursts (GRBs) were a rarely detected phenomenon, thus their nature is unclear. During the afterglow of GRB 050502B, t…
Swift and XMM observations of the dark GRB 050326
A. Moretti, A. De Luca, D. Malesani +30
We present Swift and XMM observations of GRB 050326, detected by Swift-BAT. The fluence was 7.7x10^-6 erg cm^-2 (20-150 keV), and its spectrum was hard, with a power law photon ind…
Swift observations of the prompt X-ray emission and afterglow from GRB050126 and GRB050219A

We report on the temporal and spectral characteristics of the early X-ray emission from the Gamma Ray Bursts GRB050126 and GRB050219A as observed by Swift. The X-ray light-curves o…
Discovery of an Afterglow Extension of the Prompt Phase of Two Gamma Ray Bursts Observed by Swift
S. D. Barthelmy, J. K. Cannizzo, N. Gehrels +19
BAT and XRT observations of two recent well-covered GRBs observed by Swift, GRB 050315 and GRB 050319, show clearly a prompt component joining the onset of the afterglow emission.…
The X-ray Telescope on board Swift: status and main results

The X-ray Telescope (XRT), on board the {\it Swift} satellite, provides: automated source detection and position with few arcsecond accuracy within few seconds from target acquisit…
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…
Swift observations of the X-ray bright GRB 050315
S. Vaughan, M. R. Goad, A. P. Beardmore +30
This paper discusses Swift observations of the gamma-ray burst GRB 050315 (z=1.949) from 80 s to 10 days after the onset of the burst. The X-ray light curve displayed a steep early…
GRB 050117: Simultaneous Gamma-ray and X-ray Observations with the Swift Satellite
J. E. Hill, D. C. Morris, T. Sakamoto +32
The Swift Gamma-Ray Burst Explorer performed its first autonomous, X-ray follow-up to a newly detected GRB on 2005 January 17, within 193 seconds of the burst trigger by the Swift…
A Compton reflection dominated spectrum in a peculiar accreting neutron star
Nanda Rea, Luigi Stella, Gian Luca Israel +5
We report on a puzzling event occurred during a long BeppoSAX observation of the slow-rotating binary pulsar GX 1+4. During this event, lasting about 1 day, the source X-ray flux w…
Swift XRT Observations of the Afterglow of GRB 050319
G. Cusumano, V. Mangano, L. Angelini +27
Swift discovered the high redshift GRB 050319 with the Burst Alert Telescope and began observing with its narrow field instruments only 225 s after the burst onset. The afterglow X…
Swift XRT Observations of the Breaking X-ray Afterglow of GRB 050318
M. Perri, P. Giommi, M. Capalbi +26
We report the results of Swift X-Ray Telescope (XRT) observations of GRB 050318. This event triggered the Burst Alert Telescope (BAT) aboard Swift and was followed-up with XRT and…
Detection of a huge explosion in the early Universe
G. Cusumano, V. Mangano, G. Chincarini +29
Gamma-ray Bursts (GRBs) are bright flashes of high energy photons that can last from about 10 milliseconds to 10 minutes. Their origin and nature have puzzled the scientific commun…
Very Early Optical Afterglows of Gamma-Ray Bursts: Evidence for Relative Paucity of Detection
P. W. A. Roming, P. Schady, D. B. Fox +38
Very early observations with the Swift satellite of gamma-ray burst (GRB) afterglows reveal that the optical component is not detected in a large number of cases. This is in contra…
The Swift X-ray Telescope
David N. Burrows, J. E. Hill, J. A. Nousek +21
The Swift Gamma-Ray Explorer is designed to make prompt multiwavelength observations of Gamma-Ray Bursts (GRBs) and GRB afterglows. The X-ray Telescope (XRT) enables Swift to deter…
Evidence for a Canonical GRB Afterglow Light Curve in the Swift/XRT Data
J. A. Nousek, C. Kouveliotou, D. Grupe +25
We present new observations of the early X-ray afterglows of the first 27 gamma-ray bursts (GRBs) detected with the Swift X-ray Telescope (XRT). The early X-ray afterglows show a c…
