Spektr-RG

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.

Data from 2-year sky survey by SRG/eROSITA were used to study X-ray variability of thousands of SDSS quasars. X-ray variability appeared to be linked with some physical parameters of supermassive black holes, such as theirs masses and accretion rates.

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.

Spektr-RG, James Webb Space Telescope, Gaia, and since the end of July, 2023, Euclid circle around L2 point in animations by Natan Eismon and Maxim Pupkov from the Department of Space Dynamics and Mathematical Information Processing.

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.
