Abstract

Optical spectroscopic identification of the nature of 21 unidentified southern hard X-ray objects is reported here in the framework of our campaign aimed at determining the nature of newly-discovered and/or unidentified sources detected by INTEGRAL. Our results show that 12 of these objects are Active Galactic Nuclei (AGNs), 5 are magnetic Cataclysmic Variables (CVs), and 4 are High-Mass X-ray Binaries (HMXBs), one of which is in the Large Magellanic Cloud. These identifications further underscore the importance of INTEGRAL in the study of the hard X-ray spectrum of AGNs, HMXBs and CVs, and the usefulness of a strategy of catalogues crosscorrelation plus optical spectroscopy to unveil the nature of the X-ray sources detected with INTEGRAL.
