New galaxy cluster in the Zone of Avoidance SRGe CL0512.7+3712. Discovery and multi-wavelength characterization

Ildar Khabibullin, Eugene Churazov, Natalya Lyskova +9

The census of massive clusters of galaxies in the local Universe is almost complete, thanks to their prominent observational signatures at X-ray, optical, and sub-mm wavelengths. N…

Is the Fermi source 4FGL J1824.2+1231 a transitional millisecond pulsar?

D. A. Zyuzin, A. V. Karpova, A. Yu. Kirichenko +9

Transitional millisecond pulsars (tMSPs) in tight binary systems represent an important evolutionary link between low-mass X-ray binaries and radio millisecond pulsars. To date, on…

SRGe J194401.8+284452 -- an X-ray Cataclysmic Variable in the Field of the Gamma-Ray Source 4FGL J1943.9+2841

A. I. Kolbin, A. V. Karpova, M. V. Suslikov +19

SRGe J194401.8+284452 is the brightest point-like X-ray object within the position uncertainty ellipse of an unidentified -ray source 4FGL J1943.9+2841. We performed multi-wavel…

A Joint SRG/eROSITA + ZTF Search: Discovery of a 97-min Period Eclipsing Cataclysmic Variable with Evidence of a Brown Dwarf Secondary

Ilkham Galiullin, Antonio C. Rodriguez, Shrinivas R. Kulkarni +24

Cataclysmic variables (CVs) that have evolved past the period minimum during their lifetimes are predicted to be systems with a brown dwarf donor. While population synthesis models…

SRGeJ045359.9+622444: A 55-min Period Eclipsing AM CVn Discovered from a Joint SRG/eROSITA + ZTF Search

Antonio C. Rodriguez, Ilkham Galiullin, Marat Gilfanov +24

AM CVn systems are ultra-compact binaries where a white dwarf accretes from a helium-rich degenerate or semi-degenerate donor. Some AM CVn systems will be among the loudest sources…
