X-ray astrophysics

The new catalogue includes more than one and a half thousand objects. Mikhail Pavlinsky ART-XC telescope is one of the two instruments aboard Russian Spektr-RG space observatory, currently working in L2 point.

SN2024ggi, a II-type supernova, was first found on April 11, 2024 by ATLAS project team. It sits in a nearby galaxy NGC3621. Mikhail Pavlinsky ART-XC telescope onboard Spektr-RG observatory was the first to register its X-ray emission.

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 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.

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.

This finding confirms the hypothesis that the supermassive black hole in the center of our Galaxy once had been much more active that it is now. The results are published in the Nature journal.

…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.
