Spektr-RG

Large solar flares on November 9–11 2025 were the cause of solar mass ejections, which, in turn, resulted in intense geomagnetic storms. On November 10–14 2025 Mikhail Pavlinsky ART-XC telescope onboard Russian Spektr-RG observatory registered the rise in high-energy proton fluxes in L2.

The award ceremony took place on November 7, 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.

It was not a joke: on the first day of the month the number of energetic solar protons near the Lagrange point L2 increased significantly to around 14 counts per second. This was almost 7 times higher than usual background, registered by ART-XC detectors, and the most prominent rise in 5 years of monitoring Sun's activity.

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.

On December 25, 2024, delegation of cosmonauts and specialists from Yu. A. Gagarin Research & Test Cosmonaut Training Center visited IKI.

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.
