X-ray astrophysics

As today, October 10, World Space Week comes to an end, we congratulate everyone on the beginning of the space era and publish an image by the SPIN-X1-MVN X-ray monitor, which has been operating aboard the International Space Station since February 2025.

Mikhail Pavlinsly ART-XC X-ray telescope studies the properties of the nuclear stellar disc of the Milky Way.

During its all-sky survey, Mikhail Pavlinsly ART-XC telescope aboard the Spektr-RG observatory discovered a previously unknown X-ray source, SRGA J230631.0+155633. Further studies revealed that this is one of the most powerful and interesting quasars that have existed in the Universe over the past five billion years.

After 22.5 years of successful operation ESA's INTEGRAL international orbital observatory, launched in 2002 by Russia, completed its scientific mission.

The team of astrophysicists from IKI and other organizations used X-ray data collected by SRG/eROSITA telescope onboard Spektr-RG observatory to look into the hot interior of the S147/Spaghetti nebula and explain its unusual properties.

In February 2025 in-flight tests of the MVN All-Sky X-ray Monitor installed on the outer side of the International Space Station have been successfully completed.

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 December 19, 2024 cosmonauts Alexey Ovchinin and Ivan Wagner installed the MVN single-unit instrument on the outside of the Zvezda Service Module of the ISS, as part of the planned EVA-63. MVN unit is a part of the space experiment MVN, aka All-Sky Monitor.
