摘要:

本文是INTEGRAL天文台七年来进行的硬X射线(17-60 keV)全天巡天系列中的第二篇。在这里,我们提出了一个目录中检测到的源,其中包括521个对象,其中449超过5西格玛检测阈值的时间平均的天空地图,和53个被检测到的曝光的各种子样本。在已确认的已知和疑似源中,262个是银河系(101个低质量X射线双星,95个高质量X射线双星,36个激变变星,30个其他类型),219个是河外的,包括214个活动星系核(AGN),4个星系团和星系ESO 389-G 002。持续探测到的河外源(|b| >5 deg)和银河源(|b| <5 deg)的源样本具有较高的识别完整性(分别为~96%和~94%),对星群研究具有重要价值。

英文摘要:

This paper is the second in a series devoted to the hard X-ray (17-60 keV) whole sky survey performed by the INTEGRAL observatory over seven years. Here we present a catalog of detected sources which includes 521 objects, 449 of which exceed a 5 sigma detection threshold on the time-averaged map of the sky, and 53 were detected in various subsamples of exposures. Among the identified sources with known and suspected nature, 262 are Galactic (101 low-mass X-ray binaries, 95 high-mass X-ray binaries, 36 cataclysmic variables, and 30 of other types) and 219 are extragalactic, including 214 active galactic nuclei (AGNs), 4 galaxy clusters, and galaxy ESO 389-G 002. The extragalactic (|b|>5 deg) and Galactic (|b|<5 deg) persistently detected source samples are of high identification completeness (respectively ~96% and ~94%) and valuable for population studies.
