INTEGRAL/IBIS 17-yr hard X-ray all-sky survey

ABSTRACT The International Gamma-Ray Astrophysics Laboratory (INTEGRAL), launched in 2002, continues its successful work observing the sky at energies E > 20 keV. legacy of mission already includes a large number discovered or previously poorly studied hard X-ray sources. growing INTEGRAL archive allows one to conduct an all-sky survey including deep extragalactic fields and deepest ever Galaxy. Taking advantage data gathered over 17 yr with IBIS coded-mask telescope INTEGRAL, we conducted sources, providing flux information from 290 catalogue 929 objects, 890 which exceed detection threshold 4.5σ rest are detected 4.0σ–4.5σ belong known catalogued Among identified sources suspected nature, 376 associated Galaxy Magellanic clouds, 145 low-mass 115 high-mass binaries, 79 cataclysmic variables, 37 other types; 440 extragalactic, 429 active galactic nuclei (AGNs), 2 ultra-luminous 1 supernova (AT2018cow), 8 galaxy clusters. 113 remain unclassified. 46 objects band for first time. LogN-LogS distribution 356 non-blazar AGNs is measured down × 10−12 erg s−1 cm−2 can be described by power law slope 1.44 ± 0.09 normalization 10−3 deg−2 10−11 cm−2. unclassified indicates that majority them origin.
