The AGN nature of three INTEGRAL sources: IGR J18249-3243, IGR J19443+2117 and IGR J22292+6647
R. Landi, J. B. Stephen, N. Masetti +6
The third INTEGRAL/IBIS survey has revealed several new hard X-ray sources, which are still unclassified. To identify these sources, we need to find their counterparts at other wav…
Renewed activity from the X-ray transient SAXJ 1810.8-2609 with INTEGRAL
M. Fiocchi, L. Natalucci, J. Chenevez +8
We report on the results of INTEGRAL observations of the neutron star low mass X-ray binary SAX J1810.8-2609 during its latest active phase in August 2007. The current outburst is…
The INTEGRAL long monitoring of persistent Ultra Compact X-ray Bursters
M. Fiocchi, A. Bazzano, P. Ubertini +3
The combination of compact objects, short period variability and peculiar chemical composition of the Ultra Compact X-ray Binaries make up a very interesting laboratory to study ac…
INTEGRAL/IBIS and Swift/XRT observations of hard cataclysmic variables
R. Landi, L. Bassani, A. J. Dean +5
The analysis of the third INTEGRAL/IBIS survey has revealed several new cataclysmic variables, most of which turned out to be intermediate polars, thus confirming that these object…
Multiwavelength observations of 3C 454.3. I. The AGILE 2007 November campaign on the "Crazy Diamond"
S. Vercellone, A. W. Chen, V. Vittorini +68
[Abridged] We report on a multiwavelength observation of the blazar 3C 454.3 (which we dubbed "crazy diamond") carried out on November 2007 by means of the astrophysical satellites…
A broad-band spectral analysis of eight radio loud type 1 AGN selected in the hard X-ray band
M. Molina, L. Bassani, A. Malizia +6
Starting from a complete sample of type I AGN observed by INTEGRAL in the 20-40 keV band, we have selected a set of 8 AGN which can be classified as radio loud objects according to…
