The Mikhail Pavlinsky ART-XC telescope is ideally suited for sensitive wide-field X-ray surveys covering tens to hundreds square degrees per day. This allows us to search for new populations of X-ray transients, that are too weak to be discovered by all-sky monitors and too rare to be serendipitously found by other grazing-incidence mirror X-ray telescopes. Most of these transients are...

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...

22. A joint SRG/eROSITA + ZTF search: Discovery of two eclipsing cataclysmic variables SRGeJ045359.9+622444 and SRGeJ041130.3+685350

We report the study and characterization of two new eclipsing CVs (SRGeJ045359.9+622444 (SRGeJ0453) and SRGeJ041130.3+685350 (SRGeJ0411)) discovered from a joint SRG/eROSITA and ZTF program. These objects were identified as CV candidates in a crossmatch of a 1200 $\rm deg^2$ patch of sky of SRG/eROSITA X-ray data with Gaia proper motion data and the optical ZTF database. SRGeJ0453 and...
