New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes during the First Five SRG All-Sky X-ray Surveys
Grigory Uskov, Sergey Sazonov, Igor Zaznobin +8
We present the results of our identification of 14 X-ray sources detected in the eastern Galactic sky ( ) in the 4-12 keV energy band on the combined map of the firs…
First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z<0.6
S. Sazonov, M. Gilfanov, P. Medvedev +22
We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0<l<180…
Optical identification of active galactic nucleus candidates detected by the Mikhail Pavlinsky ART-XC telescope aboard the SRG observatory during the all-sky X-ray survey
I. A. Zaznobin, G. S. Uskov, S. Yu. Sazonov +12
We present the results of our identification of eight objects from a preliminary catalogue of X-ray sources detected in the 4-12 keV energy band by the Mikhail Pavlinsky ART-XC tel…
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…
SRG/eROSITA uncovers the most X-ray luminous quasar at z>6
P. Medvedev, S. Sazonov, M. Gilfanov +6
We report the discovery of X-ray emission from CFHQS J142952+544717, the most distant known radio-loud quasar at z=6.18, on Dec. 10--11, 2019 with the eROSITA telescope on board th…
Optical Identification of X-ray Sources from the 14-Year INTEGRAL All-Sky Survey
D. I. Karasev, A. A. Lutovinov, A. Yu. Tkachenko +6
We present the results of our optical identifications of several hard X-ray sources from the INTEGRAL all-sky survey obtained over 14 years of observations. Having improved the pos…
