ART-XC

After the first few days of observations a new X-ray source turned out to be a pulsar in a binary system with a low-mass companion.

Mikhail Pavlinsky X-ray telescope on-board Russian Spektr-RG observatory has completed the full survey of the Milky Way plane and now is going on with the all-sky survey, which was suspended in the spring of 2022.

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.

On July 13, 2023 Spektr-RG space observatory marks its fourth year since the launch. More that 1.1 terabytes of telemetry data have been downstreamed to the Earth, which later turned into tens of terabytes of scientific data. More than 70 papers have been already published, which investigate hundreds and thousands of X-ray sources.

Supernova SN 2023ixf, which blasted on May 18 in the Pinwheel Galaxy M101, appeared to become more and more bright in X-rays even after its optical luminosity started to fade. The results of the observations were published in Astronomer's Telegram.

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 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.
