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…
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…
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…
