850 SRG/eROSITA X-ray sources associated with Pleiades stars
I. M. Khamitov, I. F. Bikmaev, M. R. Gilfanov +2
Using data from the SRG/eROSITA all-sky X-ray survey and the GAIA-based catalog of 2,209 members of the Pleiades open star cluster, we found 850 X-ray sources associated with the c…
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…
Superflare on a rapidly-rotating solar-type star captured in X-rays
Andrey Mukhin, Roman Krivonos, Ilfan Bikmaev +5
In this work, we studied X-ray source SRGe~J021932.4040154 (SRGe J021932), which we associated with a single X-ray active star of spectral class G2V-G4V and the rotational perio…
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…
Optical identification and follow-up observations of SRGA J213151.5+491400 -- a new magnetic cataclysmic variable discovered with SRG Observatory
Ş. Balman, I. Khamitov, A. Kolbin +21
We report results of optical identification and multi-wavelength study of a new polar-type magnetic cataclysmic variable (MCV), SRGA J213151.5+491400, discovered by Spectrum Roentg…
