During its all-sky survey, Mikhail Pavlinsly ART-XC telescope aboard the Spektr-RG observatory discovered a previously unknown X-ray source, SRGA J230631.0+155633. Further studies revealed that this is one of the most powerful and interesting quasars that have existed in the Universe over the past five billion years.

In 2024, IKI scientists and their colleagues completed the analysis of the data from the Milky Way central region deep survey and the first five all-sky surveys (2019–2022) made by Mikhail Pavlinsky ART-XC telescope onboard Spektr-RG X-ray observatory.

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.
