ART-XC

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.

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.

The Prime Minister of Russia, Mikhail Mishustin presented Government science and technology awards on November 27, 2024.

On July 13, 2019, Proton rocket launcher with DM-03 booster blasted off from Baikonur cosmodrome, carrying Russian X-ray observatory Spektr-RG. Today, we name some — but by no means the only — fascinating results of its work in these five years.

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.
