Description
Results of the spectroscopic observations at the 1.5-m Russian-Turkish telescope for another group of 12 X-ray sources discovered by the eROSITA telescope onboard the SRG space observatory and identified by the SRGz machine learning system as candidates for distant X-ray quasars are presented. Ten objects have been confirmed as quasars at redshifts z = 2.6-3.2 and two sources have turned out to be active galactic nuclei (AGNs) at z = 0.42 and 1.02.
