INTEGRAL IBIS 9-Year Galactic Hard X-Ray Survey Catalog

Description

The INTEGRAL observatory operating in a hard X-ray/gamma domain has gathered a large observational data set over nine years starting in 2003. Most of the observing time was dedicated to the Galactic source population study, making possible the deepest Galactic survey in hard X-rays ever compiled. The authors aimed to perform a Galactic survey that could be used as the basis of Galactic source population studies, and performed mapping of the Milky Way in hard X-rays over the maximum exposure available at Galactic latitudes |b| < 17.5 degrees. They used sky reconstruction algorithms especially developed for the high quality imaging of INTEGRAL/IBIS data. In their paper. they presented sky images, sensitivity maps, and catalogs of detected sources in the three energy bands 17 - 60, 17 - 35, and 35 - 80 keV in the Galactic plane at |b| < 17.5 degrees. The total number of sources in the reference 17 - 60 keV band includes 402 objects exceeding a 4.7-sigma detection threshold on the nine-year time-averaged map. Among the identified sources with known and tentatively identified natures, 253 are Galactic objects (108 low-mass X-ray binaries, 82 high-mass X-ray binaries, 36 cataclysmic variables, and 27 are of other types), and 115 are extragalactic objects, including 112 active galactic nuclei and 3 galaxy clusters. The sample of Galactic sources with S/N > 4.7 sigma has an identification completeness of ~92%, which is valuable for population studies. Since the survey is based on the nine-year sky maps, it is optimized for persistent sources and may be biased against finding transients. This table contains the catalog of 402 INTEGRAL sources exceeding the detection threshold in the 17 - 60 keV energy band. This table was created by the HEASARC in September 2012 based on CDS CATALOG J/A+A/545/A27 file catalog.dat. This is a service provided by NASA HEASARC .
