Abstract (from CDS):

The IBIS imager on board INTEGRAL, with a sensitivity better than a milliCrab in deep observations and a point-source location accuracy on the order of few arcminutes, has thus far localized 723 hard X-ray sources in the 17-100 keV energy band, of which about 1/3 are still unclassified. The aim of this paper is to provide subarcsecond localizations of the unidentified sources, necessary to pinpoint the optical and/or infrared (IR) counterpart of those objects whose nature is so far unknown. Cross-correlation between the new IBIS sources published in the fourth INTEGRAL/IBIS Survey catalog and the Chandra/ACIS data archive resulted in a sample of five previously unidentified objects. We present here the results of Chandra X-ray Observatory observations of these five hard X-ray sources discovered by the INTEGRAL satellite. We associated IGR J10447-6027 with IR source 2MASS J10445192-6025115, IGR J16377-6423 with the cluster CIZA J1638.2-6420, IGR J14193-6048 with the pulsar with nebula PSR J1420-6048, and IGR J12562+2554 with the quasar SDSS J125610.42+260103.5. We suggest that the counterpart of IGR J12288+0052 may be an active galactic nucleus/quasi-stellar object type 2 at a confidence level of 90%.
