Modelling the spectral response of the Swift-XRT CCD camera: Experience learnt from in-flight calibration
O. Godet, A. P. Beardmore, A. F. Abbey +11
(Abbreviated) We show that the XRT spectral response calibration was complicated by various energy offsets in photon counting (PC) and windowed timing (WT) modes related to the way…
The Swift X-Ray Telescope: Status and Performance
David N. Burrows, J. A. Kennea, A. F. Abbey +23
We present science highlights and performance from the Swift X-ray Telescope (XRT), which was launched on November 20, 2004. The XRT covers the 0.2-10 keV band, and spends most of…
Line Searches in Swift X-ray Spectra
C. P. Hurkett, S. Vaughan, J. P. Osborne +14
Prior to the launch of the Swift mission several X-ray line detections were reported in Gamma Ray Burst afterglow spectra. To date, these pre-Swift era results have not been conclu…
The 26 year-long X-ray light curve and the X-ray spectrum of the BL Lac Object 1E 1207.9+3945 in its brightest state
A. Maselli, P. Giommi, M. Perri +4
We studied the temporal and spectral evolution of the synchrotron emission from the high energy peaked BL Lac object 1E 1207.9+3945. Two recent observations have been performed by…
Multifrequency Observations of the Blazar 3C 279 in January 2006
WEBT Collaboration, W. Collmar, M. Böttcher +13
We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279, which was organised around an INTEGRAL ToO observat…
A study of the prompt and afterglow emission of the Short GRB 061201
G. Stratta, P. D'Avanzo, S. Piranomonte +30
Our knowledge of the intrinsic properties of short duration Gamma-Ray Bursts has relied, so far, only upon a few cases for which the estimate of the distance and an extended, multi…
