New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes during the First Five SRG All-Sky X-ray Surveys
Gilfanov, M. R.; Medvedev, P. S.; Sunyaev, R. A. +8 more
We present the results of our identification of 14 X-ray sources detected in the eastern Galactic sky ($0^{\circ}<l<180^{\circ}$) in the 4-12 keV energy band on the combined map of the first five all-sky surveys (from December 2019 to March 2022) with the Mikhail Pavlinsky ART-XC telescope onboard the SRG observatory. All 14 sources are reli…
SRG/ART-XC Galactic Plane Survey near Galactic Longitude L 20°: Catalog of Sources
Sazonov, S. Yu.; Lutovinov, A. A.; Karasev, D. I. +11 more
We present a catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope onboard the SRG space observatory during the observations of the Galactic plane region near a longitude l~20° (L20 field) in October 2019. The L20 field was observed four times in the scanning mode, which provided a uniform coverage of the sky region with a total ar…
X-ray Properties of the Luminous Quasar PG 1634+706 at z=1.337 from SRG and XMM-Newton Data
Gilfanov, M. R.; Sunyaev, R. A.; Sazonov, S. Yu. +2 more
In the fall of 2019, during the in-flight calibration phase of the SRG observatory, the onboard eROSITA and Mikhail Pavlinsky ART-XC telescopes carried out a series of observations of PG 1634+706 — one of the most luminous (an X-ray luminosity ${∼}10^{46}$ erg s${}^{-1}$) quasars in the Universe at $z<2$. Approximately at the same dates this qu…
