SRG/eROSITA catalogue of X-ray active SDSS dwarf galaxies
S. D. Bykov, M. R. Gilfanov, R. A. Sunyaev
We present a sample of 99 dwarf galaxies () with X-ray activity in their central regions. The sample was obtained from a match of the SRG/eROSITA X-ray catalo…
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…
Highly Variable Active Galactic Nuclei in the SRG/eROSITA All-Sky Survey: I. Constructing Sample and Catalog of Sources Detected in Low State
Pavel Medvedev, Marat Gilfanov, Sergey Sazonov +2
We present the results of our search for highly variable active galactic nuclei (AGNs) the X-ray flux from which changed by more than an order of magnitude during the SRG/eROSITA a…
SRG/eROSITA Survey in the Lockman Hole: Classification of X-ray Sources
M. I. Belvedersky, S. D. Bykov, M. R. Gilfanov
We have classified the point-like X-ray sources detected by the SRG/eROSITA telescope in the deep Lockman Hole survey. The goal was to separate the sources into Galactic and extrag…
A new redback pulsar candidate 4FGL J2054.2+6904
A. V. Karpova, D. A. Zyuzin, Yu. A. Shibanov +1
The Fermi catalogue contains about 2000 unassociated -ray sources. Some of them were recently identified as pulsars, including so called redbacks and black widows, which are mil…
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…
