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…
Joint ALMA/X-ray monitoring of the radio-quiet type 1 AGN IC 4329A
E. Shablovinskaya, C. Ricci, C-S. Chang +20
The origin of a compact millimeter (mm, 100-250 GHz) emission in radio-quiet active galactic nuclei (RQ AGN) remains debated. Recent studies propose a connection with self-absorbed…
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…
Small telescopes being effective: MAGIC or not?
Victor L. Afanasiev, Eugene A. Malygin, Elena S. Shablovinskaya +4
The paper describes the MAGIC multi-mode focal reducer (Monitoring of Active Galaxies by Investigation of their Cores), commissioned on the 1-m Zeiss-1000 telescope of the Special…
Optical Counterparts of Two Candidate Ultraluminous X-ray Sources in NGC 4536
H. Avdan, E. Sonbas, K. S. Dhuga +7
Archival {\it XMM-Newton}, {\it Chandra} and {\it Hubble Space Telescope (HST)} data have been used to study the X-ray and optical properties of two candidate ultraluminous X-ray s…
SRGe2149+6736 -- the new candidate to AM~Her type variables discovered by eROSITA telescope on "Spectrum--Roentgen--Gamma" orbital observatory
I. F. Bikmaev, A. I. Kolbin, V. V. Shimansky +18
We present the results of the optical identification, classification, as well as analysis of photometric and spectral observations of the X-ray transient SRGe2149+6736 detected by…
Discovery of the most X-ray luminous quasar SRGE J170245.3+130104 at redshift z
G. A. Khorunzhev, A. V. Meshcheryakov, P. S. Medvedev +10
SRGE J170245.3+130104 was discovered by the eROSITA telescope aboard the SRG space observatory on March 13-15, 2020 during the first half-year scan of its all-sky X-ray survey. The…
Measurement of the supermassive black hole masses in two active galactic nuclei by the photometric reverberation mapping method
E. A. Malygin, E. S. Shablovinskaya, R. I. Uklein +1
We present the results of long-term photometric monitoring of two active galactic nuclei, 2MASX J08535955+7700543 (z 0.106) and VII Zw 244 (z 0.131), being investigat…
Spectroscopy and polarimetry of the gravitationally lensed quasar Q0957+561
L. Č. Popović, V. L. Afanasiev, E. S. Shablovinskaya +2
We present new spectroscopic and polarimetric observations of the first discovered gravitational lens Q0957+561 obtained with the 6m telescope of the Special Astrophysical Observat…

Inverse Compton Scattering of Radiation from a Central Source as a Possible Mechanism for the Formation of X-Ray Radiation from Kiloparsec Jets of Core-Dominated Quasars
M. S. Butuzova, A. B. Pushkarev, E. S. Shablovinskaya +1
For the interpretation of X-ray radiation from kiloparsec jets of quasars, the inverse Compton scattering of the cosmic microwave background has been widely used for almost 20 year…
