The 1.4 GHz radio properties of hard X-ray selected AGN
F. Panessa, A. Tarchi, P. Castangia +7
We have analyzed the NVSS and SUMSS data at 1.4 GHz and 843 MHz for a well defined complete sample of hard X-ray AGN observed by INTEGRAL. A large number (70/79) of sources are det…
IGR J17488-2338: a newly discovered giant radio galaxy
Manuela Molina, L. Bassani, A. Malizia +4
We present the discovery of a large scale radio structure associated with IGR J17488--2338, a source recently discovered by \emph{INTEGRAL} and optically identified as a broad line…
The INTEGRAL high energy cut-off distribution of type 1 AGN
A. Malizia, M. Molina, L. Bassani +4
In this letter we present the primary continuum parameters, the photon index Gamma and the high energy cut-off Ec, of 41 type-1 Seyfert galaxies extracted from the INTEGRAL complet…
New insights on accretion in Supergiant Fast X-ray Transients from XMM-Newton and INTEGRAL observations of IGR J175442619
S. P. Drave, A. J. Bird, L. Sidoli +4
XMM-Newton observations of the supergiant fast X-ray transient IGRJ175442619 are reported and placed in the context of an analysis of archival INTEGRAL/IBIS data that provide…
