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…
On the nature of the X-ray pulsar SAX J1324-6200
S. Mereghetti, P. Romano, L. Sidoli
We present recent observations of the X-ray pulsar SAX J1324-6200 obtained in December 2007 with the Swift satellite yielding a significant improvement in the source localization w…
An alternative hypothesis for the outburst mechanism in Supergiant Fast X-ray Transients: the case of IGR J11215-5952
L. Sidoli, P. Romano, S. Mereghetti +4
(ABRIDGED)- The physical mechanism responsible for the short outbursts in a recently recognized class of High Mass X-ray Binaries, the Supergiant Fast X-ray Transients (SFXTs), is…
Swift/XRT observes the fifth outburst of the periodic Supergiant Fast X-ray Transient IGR J11215-5952
P. Romano, L. Sidoli, V. Mangano +2
IGR J11215-5952 is a hard X-ray transient source discovered in April 2005 with INTEGRAL and a confirmed member of the new class of High Mass X-ray Binaries, the Supergiant Fast X-r…
Long term spectral variability in the soft gamma ray repeater SGR 1900+14
P. Esposito, S. Mereghetti, A. Tiengo +3
We present a systematic analysis of all the BeppoSAX data of SGR 1900+14. The observations spanning five years show that the source was brighter than usual on two occasions: ~20 da…
GX 301-2 as seen by Integral
I. Kreykenbohm, K. Pottschmidt, P. Kretschmar +9
We present observations of the High Mass X-ray Binary GX 301-2 taken during the Galactic Plane Scan (GPS) with Integral following our RXTE observations (Kreykenbohm et al. 2004). T…
