Data from 2-year sky survey by SRG/eROSITA were used to study X-ray variability of thousands of SDSS quasars. X-ray variability appeared to be linked with some physical parameters of supermassive black holes, such as theirs masses and accretion rates.

Ceremonial awarding was held on March 4, 2023 at MIPT's campus in Dolgoprudnyi.

At first AT2020mrf seemed to be an ordinary optical transient, but thanks to SRG/eROSITA discovery of a new X-ray source in the same place it became clear that the astrophysicists have encountered the most peculiar object.
