IKI scientists and their colleagues from the international team got new evidence in favour of the fact that the Peanut galaxy cluster (SRGe CL0238.3+2005) undergoes a stage of collision between two giant substructures — soon after their nuclei have passed through each other. This follows from the measurements of the galaxies’ radial velocities, X-ray observations data, and dynamical simulations. The study has been published in Astronomy & Astrophysics* and the Journal of High Energy Astrophysics.

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.

On the eve of the day of Russian science, Russian Academy of Sciences awarded the winners of the 2021 competition for RAS awards for young scientists and students. Among them are IKI astrophysicicts Andrei Semena, Ilya Mereminsky, Igor Zaznobin.

On September, 1, an Astronomy Telegram from Mikhail Pavlinsky ART-XC team announced a discovery of an optical counterpart of a bright X-ray pulsar — a transient star V520 in constellation Monoceros, which is Unicorn in Greek.
