Transient X-ray Pulsar RX J0440.9+4431 Switched To the Super-Critical Regime of Accretion For the First Time... …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.
IKI Young Scientists Awarded 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.
Coma Cluster in X-Rays and Radio 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.
Getting grips on a strongly magnetized neutron star geometry Researchers from the Space Research Institute and their colleagues determined geometrical parameters of a neutron star floating in the Galaxy 21,000 light years away. The finding confirms old ideas that this star precesses like a whirligig. The results were published in Nature Astronomy.
A GRB-to-be did not appear in X-rays 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,..
X-Ray Unicorn Brighter in Summer 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.
X-ray transients on the Mikhail Pavlinsky ART-XC map Russian Academy of Sciences announced 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.
Three years in X-ray sky On 13 July 2019 a long-awaited Spektr-RG mission soared up from Baikonur to reveal the hidden X-ray Universe with its two telescopes — eROSITA and ART-XC.
