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…
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…
Swift monitoring of Supergiant Fast X-ray Transients: the out-of-outburst behaviour and the flares from IGRJ17544-2916 and XTEJ1739-302
L. Sidoli, P. Romano, G. Cusumano +10
Supergiant Fast X-ray Transients (SFXTs) are a sub-class of High Mass X-ray Binaries (HMXBs) associated with OB supergiant companions and displaying transient X-ray activity. This…
Monitoring Supergiant Fast X-ray Transients with Swift. III. Outbursts of the prototypical SFXTs IGR J17544-2619 and XTE J1739-302
L. Sidoli, P. Romano, V. Mangano +7
IGR J17544-2619 and XTE J1739-302 are considered the prototypical sources of the new class of High Mass X-ray Binaries, the Supergiant Fast X-ray Transients (SFXTs).These sources w…
Scaler Mode Technique for the ARGO-YBJ Detector
G. Aielli et al.
The ARGO-YBJ experiment has been designed to study the Extensive Air Showers with an energy threshold lower than that of the existing arrays by exploiting the high altitude locatio…
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…
