TL;DR: The Swift X-ray Telescope (XRT) as mentioned in this paper is designed to make astrometric, spectroscopic, and photometric observations of Xray emission from Gamma-ray Bursts and their afterglows in the energy band 0.2-10 keV.

TL;DR: In this paper, the authors analyzed all significant X-ray flares from the first 110 GRBs observed by Swift and found that the peak energy of the observed flares is typically in the soft Xray band.

TL;DR: Swift observations of the � -ray burst GRB 050315 from 80 s to 10 days after the onset of the burst suggest that the rapidly decaying, early X-ray emission was simply a continuation of the fading prompt prompt emission; this strongsimilarity to that of the prompt hard X-rays/� -ray emission is suggested.

TL;DR: In this article, the authors analyzed all significant X-ray flares from the first 110 gamma ray bursts observed by Swift and found that the average fluence of the flares is 2.4e-7 erg/cm^2/s in the 0.2-10 keV energy band, which is approximately a factor of ten below the average prompt GRB fluence.

TL;DR: In this paper, the authors present observations of XRF 050406, the first burst detected by Swift showing a flare in its X-ray light curve, which indicates that the producing mechanism is late internal shocks, which implies that the central engine is still active at 210 s, though with a reduced power with respect to the prompt emission.
