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…
The polar IL Leo in a low accretion state
M. V. Suslikov, A. I. Kolbin, N. V. Borisov
We performed an optical study of the magnetic period-bouncer candidate IL Leo. Long-term photometric analysis over years reveals multiple state transitions. Modelling…
Phase-Resolved Spectroscopy of the Polar V379 Vir with a Brown Dwarf
M. V. Suslikov, A. I. Kolbin, N. V. Borisov
The polar V379 Vir is a well-known magnetic cataclysmic variable with a brown dwarf donor. Despite numerous studies of this system across various spectral ranges, a detailed invest…
On accretion in the polar V379 Vir
M. V. Suslikov, A. I. Kolbin, N. V. Borisov
Based on optical and infrared survey data spanning years of observations, the long-term variability of the polar V379 Vir with a brown dwarf secondary has been studied…
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…
Gaia 19cwm -- an eclipsing dwarf nova of WZ Sge type with a magnetic white dwarf
A. I. Kolbin, T. A. Fatkhullin, E. P. Pavlenko +6
The spectral and photometric studies of the cataclysmic variable Gaia 19cwm (or ZTF19aamkwxk) have been performed. Based on the analysis of long-term variability, it is concluded t…
Spectroscopic and photometric study of the new eclipsing polar Gaia23cer
A. I. Kolbin, E. P. Pavlenko, V. Yu. Kochkina +11
We present the results of the optical study of the new eclipsing polar Gaia23cer. We analyzed the brightness variability of the polar in high ($\langle r \rangle \approx 16.5\mathr…
Merger of massive galaxy cluster CL0238.3+2005 at z~0.4: just after pericenter passage?
N. Lyskova, E. Churazov, I. Khabibullin +13
Massive clusters of galaxies are very rare in the observable Universe. Even rarer are mergers of such clusters observed close to pericenter passage. Here, we report on one such cas…
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…
Optical Identification and Spectroscopic Redshift Measurements of 216 Galaxy Clusters from the SRG/eROSITA All-Sky Survey
I. A. Zaznobin, R. A. Burenin, A. A. Belinski +34
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The spectrosco…
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…
SDSS J085414.02+390537.3 -- a new asynchronous polar
A. I. Kolbin, M. V. Suslikov, V. Yu. Kochkina +3
The asynchrony of the polar SDSS~J085414.02+390537.3 was revealed using the data of ZTF photometric survey. The light curves show a beat period ~days. Duri…
Optical study of the polar BM CrB in low accretion state
A. I. Kolbin, N. V. Borisov, A. N. Burenkov +3
This paper presents a spectral and photometric study of the poorly studied polar BM CrB. Three states of the polar brightness and signs of transition from one-pole to two-pole accr…
