Description
We describe the survey of the Galactic Bulge, performed by the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory. In order to obtain the maximal sensitivity the special source detection algorithm was developed, which helped to reduce unusable areas around bright sources, populating the region. Using this algorithm a total of 172 point sources were detected. Of these, 153 are registered on the average 4--12 keV map and 18 sources are either extremely hard (detected only at energies above 7~keV) or highly variable (detected only in individual scans shorter than a day). For 121 sources, there are plausible counterparts in other X-ray source catalogs, including 43 with known classification. The remaining 51 sources are previously unknown objects, discovered by SRG/ART during the Galactic Bulge survey. Using our estimation of the sensitivity and Galaxy mass model we produced the prediction of the content of the obtained sample with different classes of sources.
