Mikhail Pavlinsky ART-XC X-Ray telescope and Integral observatory look at Swift J1727.8-1613 X-Ray nova – the brightest object in the summer X-ray sky of 2023.

Astrophysicists from IKI and Ioffe Institute of the Russian Academy of Sciences studied compact star cluster Westerlund 2. The paper with the results of the study is accepted for publication in MNRAS and is available on arXiv.org.

This finding confirms the hypothesis that the supermassive black hole in the center of our Galaxy once had been much more active that it is now. The results are published in the Nature journal.

…and went back again. Literally all X-ray space observatories studied this outburst in 2023, and among them was Integral. The paper with the first results of the observations was sent to MNRAS and published on arXiv.org. The picture from the paper was selected as the June 2023 Picture of the Month of the Integral observatory.

Russian Mikhail Pavlinsky ART-XC X-ray telescope onboard Spektr-RG observatory (Roscosmos) and Russian KONUS instrument onboard WIND spacecraft (NASA), residing in two opposite Lagrange points L1 and L2, have provided a detailed study of GRB 221009A — the brightest of all gamma-ray bursts previously registered by Konus and most likely the brightest one in the whole history of mankind.

On 1 March 2023 Academician Rashid A. Sunyaev, one of the world renowned astrophysicists, celebrates its 80th birthday. He is famous for many results, which have entered modern textbooks for theoretical astrophysics and cosmology all over the world.

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.

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.
