Where are Compton-thick radio galaxies? A hard X-ray view of three candidates
F. Ursini, L. Bassani, F. Panessa +4
We present a broad-band X-ray spectral analysis of the radio-loud active galactic nuclei NGC 612, 4C 73.08 and 3C 452, exploiting archival data from NuSTAR, XMM-Newton, Swift and I…
Investigating the nature of INTEGRAL Gamma-ray Bursts and sub-threshold triggers with Swift follow up
A. B. Higgins, R. L. C. Starling, D. Götz +9
We explore the potential of INTEGRAL to improve our understanding of the low fluence regime for explosive transients, such as GRBs. We probe the nature of the so-called "WEAK" INTE…
First hard X-ray detection and broad band X-ray study of the unidentified transient AX J1949.8+2534
V. Sguera, L. Sidoli, A. Paizis +3
We present the results from INTEGRAL and Swift/XRT observations of the hitherto poorly studied unidentified X-ray transient AX J1949.8+2534, and on archival multiwavelength observa…
Investigating the X-ray counterparts to unidentified sources in the 1000-orbit INTEGRAL/IBIS catalogue
R. Landi, L. Bassani, A. Bazzano +6
The latest INTEGRAL/IBIS all-sky survey lists 219 hard X-ray sources whose nature is still unknown. We report on our ongoing campaign aimed at identifying these high-energy emitter…
The nature of fifty Palermo Swift-BAT hard X-ray objects through optical spectroscopy
A. F. Rojas, N. Masetti, D. Minniti +16
We present the nature of 50 hard X-ray emitting objects unveiled through an optical spectroscopy campaign performed at seven telescopes in the northern and southern hemispheres. Th…
