IGR J16328-4726: a new candidate Supergiant Fast X-ray Transient
M. Fiocchi, V. Sguera, A. Bazzano +4
The unidentified source IGR J16328-4726 was covered with INTEGRAL observations for a long period (~9.8Ms) and was undetectable for most of the time while showing a very recurrent m…
Discovery of the 51.47 day orbital period in the supergiant fast X-ray transient XTE J1739-302 with INTEGRAL
S. P. Drave, D. J. Clark, A. J. Bird +5
Timing analysis of ~12.4 Ms of INTEGRAL/IBIS data has revealed a period of 51.47 +/- 0.02 days in the supergiant fast X-ray transient source XTE J1739-302/IGR J17391-3021 that can…
Five new INTEGRAL unidentified hard X-Ray sources uncovered by Chandra
M. Fiocchi, L. Bassani, A. Bazzano +4
The IBIS imager on board INTEGRAL, with a sensitivity better than a mCrab in deep observations and a point source location accuracy of the order of few arcminutes, has localized so…
XMM-Newton observations of unidentified INTEGRAL/IBIS sources
A. Malizia, L. Bassani, V. Sguera +4
About 30% of the sources in the 4th INTEGRAL-IBIS catalogue are unidentified in that they lack an optical counterpart. To be able to classify them, X-ray observations are of crucia…
The orbital period in the supergiant fast X-ray transient IGR J16465--4507
D. J. Clark, V. Sguera, A. J Bird +6
Timing analysis of the INTEGRAL-IBIS and Swift-BAT light curves of the Supergiant Fast X-ray Transient (SFXT) IGR J16465-4507 has identified a period of 30.32+/-0.02 days which we…
INTEGRAL deep observations of the Small Magellanic Cloud
M. J. Coe, A. J. Bird, D. A. H. Buckley +12
Deep observations of the Small Magellanic Cloud (SMC) and region were carried out in the hard X-ray band by the INTEGRAL observatory in 2008-2009. The field of view of the instrume…
Swift/XRT follow-up observations of unidentified INTEGRAL/IBIS sources
R. Landi, L. Bassani, A. Malizia +4
Many sources listed in the 4th IBIS/ISGRI survey are still unidentified, i.e. lacking an X-ray counterpart or simply not studied at lower energies (< 10 keV). The cross-correlation…
Re-evaluating the Local Compton-thick AGN Fraction
A. Malizia, J. B. Stephen, L. Bassani +3
We study the NH distribution in a complete sample of 88 AGN selected in the 20-40 keV band from INTEGRAL/IBIS observations. We find that the fraction of absorbed (NH > 10^22 cm^-2)…
Revealing the nature of new unidentified INTEGRAL sources
N. Masetti, P. Parisi, E. Palazzi +17
Since its launch on October 2002, the INTEGRAL satellite has revolutionized our knowledge of the hard X-ray sky thanks to its unprecedented imaging capabilities and source detectio…
The peculiar high-mass X-ray binary 1ES 1210-646
N. Masetti, R. Landi, V. Sguera +6
Using data collected with the BeppoSAX, INTEGRAL and Swift satellites, we report and discuss the results of a study on the X-ray emission properties of the X-ray source 1ES 1210-64…
