Swift/XRT monitoring of the Supergiant Fast X-ray Transient IGR J18483-0311 for an entire orbital period
P. Romano, L. Sidoli, L. Ducci +9
IGR J18483-0311 is an X-ray pulsar with transient X-ray activity, belonging to the new class of High Mass X-ray Binaries called Supergiant Fast X-ray Transients. This system is one…
The Palermo Swift-BAT Hard X-ray Catalogue. II- Results after 39 months of sky survey
G. Cusumano, V. La Parola, A. Segreto +12
We present the Palermo Swift-BAT hard X-ray catalogue obtained from the analysis of the the data relative to the first 39 months of the Swift mission. We have developed a dedicated…
Supergiant Fast X-ray Transients in outburst: new Swift observations of XTEJ1739-302, IGRJ17544-2619, and IGRJ08408-4503
L. Sidoli, P. Romano, L. Ducci +8
We report on new X-ray outbursts observed with Swift from three Supergiant Fast X-ray Transients (SFXTs): XTEJ1739-302, IGRJ17544-2619 and IGRJ08408-4503. The former two outbursts…
The multicomponent model of the Crab Pulsar at energies above 25 GeV
R. Campana, E. Massaro, T. Mineo +1
We review a proposed multicomponent model to explain the features of the pulsed emission and spectrum of the Crab Pulsar, on the light of the recent detection of pulsed emission ab…
The 22-Month Swift-BAT All-Sky Hard X-ray Survey
J. Tueller, W. H. Baumgartner, C. B. Markwardt +36
We present the catalog of sources detected in the first 22 months of data from the hard X-ray survey (14--195 keV) conducted with the BAT coded mask imager on the \swift satellite.…
Swift and Supergiant Fast X-ray Transients: a novel monitoring approach
P. Romano, L. Sidoli, V. Mangano +6
We describe our monitoring strategy which best exploits the sensitivity and flexibility of Swift to study the long-term behaviour of Supergiant Fast X-ray Transients (SFXTs). We pr…
Disentangling the system geometry of the Supergiant Fast X-ray Transient IGR J11215-5952 with Swift
P. Romano, L. Sidoli, G. Cusumano +3
IGR J11215-5952 is a hard X-ray transient discovered in 2005 April by INTEGRAL and a member of the new class of HMXB, the Supergiant Fast X-ray Transients (SFXTs). While INTEGRAL a…
