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 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…
