The award ceremony took place on November 7, 2025.

The team of astrophysicists from IKI and other organizations used X-ray data collected by SRG/eROSITA telescope onboard Spektr-RG observatory to look into the hot interior of the S147/Spaghetti nebula and explain its unusual properties.

New model developed by IKI astrophysicists and their colleagues and based on the data of SRG/eROSITA X-ray telescope, links the bright structure seen in our Galaxy to bubbles of hot gas that emerge from star-formation regions like smoke from the chimney.

On July 13, 2019, Proton rocket launcher with DM-03 booster blasted off from Baikonur cosmodrome, carrying Russian X-ray observatory Spektr-RG. Today, we name some — but by no means the only — fascinating results of its work in these five years.

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.

Astrophysicists from IKI and Ioffe Institute, using the data from SRG/eROSITA space telescope, studied the properties of a shock in Coma cluster of galaxies. The paper summarising their results was accepted for publication in Astronomy&Astrophysics.

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.
