Spectroscopic galaxy redshifts in the Peanut cluster -- a massive nearly head-on cluster merger shortly after pericenter passage
I. Zaznobin, N. Lyskova, I. Bikmaev +13
The Peanut cluster (SRGe J023820.8+200556, SRGe CL0238.3+2005, = 0.42) has recently emerged as a candidate for a rare, massive merger, potentially analogous to the Bulle…
X-ray emission of the Nuclear Stellar Disk as seen by SRG/ART-XC
Valentin Nezabudkin, Roman Krivonos, Sergey Sazonov +5
The Nuclear Stellar Disk (NSD), together with the Nuclear Stellar Cluster and the supermassive black hole Sgr A*, forms the central region of the Milky Way. Galactic X-ray backgrou…
SRG/ART-XC All-Sky X-ray Survey: Sensitivity Assessment Based on Aperture Photometry
N. Y. Tyrin, R. A. Krivonos, V. A. Arefiev +10
The Spectrum-Roentgen-Gamma (SRG) observatory continues to operate successfully in orbit at the Lagrange point L2. The Mikhail Pavlinsky ART-XC telescope has demonstrated high effi…
Inflight calibration of SRG/ART-XC point spread function at large off-axis angles
R. Krivonos, R. Burenin, E. Filippova +12
The knowledge of the point spread function (PSF) of the Mikhail Pavlinsky Astronomical Roentgen Telescope - X-ray Concentrator (ART-XC) telescope aboard the Spectrum-Roentgen-Gamma…
New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes during the First Five SRG All-Sky X-ray Surveys. Part 2
Grigory Uskov, Sergey Sazonov, Igor Zaznobin +8
We present the results of our identification of 11 X-ray sources detected on the half of the sky in the 4-12 keV energy band on the combined map of the first…
Constraints on the parameters of keV-scale mass annihilating Dark Matter obtained with SRG/ART-XC observations
E. I. Zakharov, V. V. Barinov, R. A. Burenin +2
In this paper we present new constraints on the velocity-independent cross section of keV-scale mass annihilating Dark Matter particles obtained with SRG/ART-XC after 4 full-sky su…
