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…
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…
Transient events in the near-nuclear regions of AGNs and quasars as the sources of the proper motion imitations
I. M. Khamitov, I. F. Bikmaev, M. R. Gilfanov +3
We present a sample of SRG/eROSITA X-ray sources located in the eastern Galactic hemisphere (0<l<180 deg), with significant proper motions according to GAIA eDR3 measurements and w…
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…
Detection of AGNs and quasars having significant proper motions according to Gaia data within SRG/eRosita X-Ray sources catalog
I. M. Khamitov, I. F. Bikmaev, M. R. Gilfanov +4
Based on a comparison of the SRG/eROSITA catalog of X-ray active stars and the Gaia catalog, a sample of 502 peculiar objects was obtained for which Gaia, on one hand, detects stat…
Long-term multiband optical variability of S5 0716+714 blazar
Mark A. Gorbachev, Marina S. Butuzova, Sergey G. Sergeev +2
Multiband optical photometry data of blazar S5 0716+714 obtained from 2002 to 2019 reveal stable color index change with flux variability. We analyzed this trend under variability…
The Transit Timing and Atmosphere of Hot Jupiter HAT-P-37b
Napaporn A-thano, Ing-Guey Jiang, Supachai Awiphan +13
The transit timing variation (TTV) and transmission spectroscopy analyses of the planet HAT-P-37b, which is a hot Jupiter orbiting an G-type star, were performed. Nine new transit…
