Unveiling the nature of INTEGRAL objects through optical spectroscopy. III. Observations of seven southern sources
N. Masetti, M. L. Pretorius, E. Palazzi +9
Context. The detection, thanks to the INTEGRAL satellite, of a number of new hard X-ray sources calls for the identification of their nature by means of observations at longer wave…
INTEGRAL/IBIS Extragalactic survey: 20-100 keV selected AGN
L. Bassani, M. Molina, A. Malizia +10
Analysis of INTEGRAL Core Program and public Open Time observations performed up to April 2005 provides a sample of 62 active galactic nuclei in the 20-100 keV band above a flux li…
Unveiling the nature of INTEGRAL objects through optical spectroscopy. II. The nature of four unidentified sources
N. Masetti, E. Mason, L. Bassani +9
We present the results of our optical spectrophotometric campaign ongoing at the Astronomical Observatory of Bologna in Loiano (Italy) on hard X-ray sources detected by INTEGRAL. W…
Is the INTEGRAL/IBIS source IGR J17204-3554 a gamma-ray emitting galaxy hidden behind the molecular cloud NGC 6334 ?
L. Bassani, A. De Rosa, A. Bazzano +9
We report on the identification of a soft gamma-ray source, IGR J17204-3554, detected with the IBIS imager on board the INTEGRAL satellite. The source has a 20-100 keV flux of ~3x1…
IGR J16393-4643: a new heavily-obscured X-ray pulsar
A. Bodaghee, R. Walter, J. A. Zurita Heras +5
An analysis of the high-energy emission from IGR J16393-4643 (=AX J1639.0-4642) is presented using data from INTEGRAL and XMM-Newton. The source is persistent in the 20-40 keV band…
The extragalactic nature of the serendipitous BeppoSAX source 2MASX J14585116-1652223
N. Masetti, E. Mason, L. Bassani +4
As a follow-up of the X-ray serendipitous detection of the source 2MASX J14585116-1652223, medium-resolution optical spectroscopic observations collected at the 1.5-metre "Cassini"…
