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 2008 May burst activation of SGR 1627-41
P. Esposito, G. L. Israel, S. Zane +16
In May 2008 the soft gamma-ray repeater SGR 1627-41 resumed its bursting activity after nearly a decade of quiescence. After detection of a bright burst, Swift pointed its X-ray te…
Observation of the suppression of the flux of cosmic rays above 4x10^19eV
The Pierre Auger Collaboration
The energy spectrum of cosmic rays above 2.5x10^18eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the flux, J ~ E…
Outliers from the mainstream: how a massive star can produce a gamma-ray burst
S. Campana, N. Panagia, D. Lazzati +12
It is now recognized that long-duration Gamma-Ray Bursts (GRBs) are linked to the collapse of massive stars, based on the association between (low-redshift) GRBs and (type Ic) core…
A Swift gaze into the 2006 March 29th burst forest of SGR 1900+14
G. L. Israel, P. Romano, V. Mangano +16
We report on the intense burst ``forest'' recorded on 2006 March 29 which lasted for ~30s. More than 40 bursts were detected both by BAT and by XRT, seven of which are rare interme…
Monitoring Supergiant Fast X-ray Transients with Swift. Rise to the outburst in IGR J16479-4514
P. Romano, L. Sidoli, V. Mangano +6
IGR J16479-4514 is a Supergiant Fast X-ray Transient (SFXT), a new class of High Mass X-ray Binaries, whose number is rapidly growing thanks to the observations of the Galactic pla…
Monitoring Supergiant Fast X-ray Transients with Swift. I. Behavior outside outbursts
L. Sidoli, P. Romano, V. Mangano +7
Supergiant Fast X-ray Transients (SFXTs) are a new class of HMXBs discovered thanks to the monitoring of the Galactic plane performed with the INTEGRAL satellite in the last 5 year…
XMM-Newton observations of the supernova remnant IC 443: II. evidence of stellar ejecta in the inner regions
Eleonora Troja, Fabrizio Bocchino, Marco Miceli +1
We investigate the spatial distribution of the physical and chemical properties of the hot X-ray emitting plasma of the supernova remnant IC 443, in order to get important constrai…
Multiwavelength analysis of the intriguing GRB 061126: the reverse shock scenario and magnetization
A. Gomboc, S. Kobayashi, C. Guidorzi +30
We present a detailed study of the prompt and afterglow emission from Swift GRB 061126 using BAT, XRT, UVOT data and multi-color optical imaging from ten ground-based telescopes. G…
