Flat-spectrum radio sources as likely counterparts of unidentified INTEGRAL sources (Research Note)
Manuela Molina, Raffaella Landi, Loredana Bassani +5
Many sources in the fourth INTEGRAL/IBIS catalogue are still unidentified, since they lack an optical counterpart. An important tool that can help in identifying/classifying these…
Swift J045106.8-694803; a highly magnetised neutron star in the Large Magellanic Cloud
Helen Klus, Elizabeth S. Bartlett, Antony J. Bird +3
We report the analysis of a highly magnetised neutron star in the Large Magellanic Cloud (LMC). The high mass X-ray binary pulsar Swift J045106.8-694803 has been observed with Swif…
The INTEGRAL source IGR J16328-4726: a High Mass X-ray Binary from the Beppo SAX era
M. Fiocchi, A. Bazzano, A. J. Bird +5
We report on temporal and spectral analysis of the INTEGRAL fast transient candidate IGR J16328-4726 observed with Beppo SAX in 1998 and more recently with INTEGRAL. The MECS X-ray…
The INTEGRAL/IBIS AGN catalogue I: X-ray absorption properties versus optical classification
A. Malizia, L. Bassani, A. Bazzano +5
In this work we present the most comprehensive INTEGRAL AGN sample which lists 272 objects. Here we mainly use this sample to study the absorption properties of active galaxies, to…
Accurate classification of 29 objects detected in the 39 months Palermo Swift/BAT hard X-ray catalogue
P. Parisi, N. Masetti, E. Jiménez-Bailón +15
Through an optical campaign performed at 4 telescopes located in the northern and the southern hemispheres, plus archival data from two on-line sky surveys, we have obtained optica…
IGR J12319-0749: evidence for another extreme blazar found with INTEGRAL
L. Bassani, R. Landi, F. E. Marshall +6
We report on the identification of a new soft gamma-ray source, IGR J12319-0749, detected with the IBIS imager on board the INTEGRAL satellite. The source, which has an observed 20…
On the periodicities present in the optical light curves of SMC Be/X-ray binaries
A. J. Bird, M. J. Coe, V. A. McBride +1
We present a comprehensive study of the periodic variations observed in OGLE I-band light curves of SMC Be/X-ray binaries, discovering new optical periodicities in 9 systems. We fi…
X-ray Pulsations from the region of the Supergiant Fast X-ray Transient IGR J17544-2619
S. P. Drave, A. J. Bird, L. J. Townsend +5
Phase-targeted RXTE observations have allowed us to detect a transient 71.49 \pm 0.02 s signal that is most likely to be originating from the supergiant fast X-ray transient IGR J1…
Unveiling the nature of INTEGRAL objects through optical spectroscopy. IX. 22 more identifications, and a glance into the far hard X-ray Universe
N. Masetti, P. Parisi, E. Jimenez-Bailon +14
(Abridged) Since its launch in October 2002, the INTEGRAL satellite has revolutionized our knowledge of the hard X-ray sky thanks to its unprecedented imaging capabilities and sour…
