A new measurement of the cosmic X-ray background
A. Moretti, C. Pagani, G. Cusumano +14
We present a new measurement of the cosmic X-ray background (CXRB) in the 1.5-7 keV energy band, performed by exploiting the Swift X-ray telescope (XRT) data archive. We also prese…
Methods and results of an automatic analysis of a complete sample of Swift-XRT observations of GRBs
P. A. Evans, A. P. Beardmore, K. L. Page +22
We present a homogeneous X-ray analysis of all 318 Gamma Ray Bursts detected by the X-ray Telescope on the Swift satellite up to 2008 July 23; this represents the largest sample of…
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…
Roma-BZCAT: A multifrequency catalogue of Blazars
E. Massaro, P. Giommi, C. Leto +5
We present a new catalogue of blazars based on multi-frequency surveys and on an extensive review of the literature. Blazars are classified as BL Lacertae objects, as flat spectrum…
First high energy observations of Narrow Line Seyfert 1s with INTEGRAL/IBIS
A. Malizia, L. Bassani, A. J. Bird +8
Narrow Line Seyfert 1 galaxies (NLS1) are very interesting objects which display peculiar properties when compared to their broad line analogues (BLS1). Although well studied in ma…
AGILE and Swift simultaneous observations of the blazar S50716+714 during the bright flare of October 2007
P. Giommi, S. Colafrancesco, S. Cutini +15
We present the results of a series of optical, UV, X-ray and gamma-ray observations of the BL Lac object S50716+714 carried out by the Swift and AGILE satellites in late 2007 when…
GRB 080319B: A Naked-Eye Stellar Blast from the Distant Universe
J. L. Racusin, S. V. Karpov, M. Sokolowski +81
Long duration gamma-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation…
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…
