Spektr-RG

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.

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 night of September 26–27 RTT-150 optical telescope in Turkey observed asteroid Didymos and its smaller counterpart Dimorphos during the impact of DART mission (NASA). RTT-150 1.5-meter telescope is part of ground-based facilities in support of Spektr-RG project.

Sometimes the fact that one did not see something makes a difference. A recent paper published by Spektr-RG science team describes a gamma-ray burst (GRB), which Spektr-RG instruments had not observed, however strange it may seem,..

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.
