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…
INTEGRAL Detection of the First Prompt Gamma-Ray Signal Coincident with the Gravitational Wave Event GW170817
V. Savchenko, C. Ferrigno, E. Kuulkers +20
We report the e INTernational Gamma-ray Astrophysics Laboratory (INTEGRAL) detection of the short gamma-ray burst GRB 170817A (discovered by Fermi-GBM) with a signal-to-noise ratio…
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…
INTEGRAL IBIS, SPI, and JEM-X observations of LVT151012
V. Savchenko, A. Bazzano, E. Bozzo +18
During the first observing run of LIGO, two gravitational wave events and one lower-significance trigger (LVT151012) were reported by the LIGO/Virgo collaboration. At the time of L…
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…
