Southern eROSITA bubble as a forward shock and the low-metallicity CGM. South-east side story
E. Churazov, I. I. Khabibullin, A. M. Bykov +4
Unlike the complicated X-ray and radio structure observed in the North Polar Spur area, the South-Eastern part of the eROSITA bubbles can be reasonably well described as a propagat…
Disentangling the Galactic centre X-ray reflection signal using XMM-Newton data
K. Anastasopoulou, I. Khabibullin, E. Churazov +5
We investigate the X-ray emission from the Galactic Centre (GC) region, focusing on the 6.4 keV fluorescent line of neutral or weakly ionised iron, which is commonly attributed to…
850 SRG/eROSITA X-ray sources associated with Pleiades stars
I. M. Khamitov, I. F. Bikmaev, M. R. Gilfanov +2
Using data from the SRG/eROSITA all-sky X-ray survey and the GAIA-based catalog of 2,209 members of the Pleiades open star cluster, we found 850 X-ray sources associated with the c…
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…
Reflection-dominated Compton-thick AGN Candidates in the SRG/eROSITA Lockman Hole Survey
M. I. Belvedersky, S. D. Bykov, M. R. Gilfanov +2
We search for reflection-dominated Compton-thick active galactic nuclei (CT AGN) candidates in the Lockman Hole region using the data of SRG/eROSITA Lockman Hole survey. We selecte…
Increase in the Brightness of the Cosmic Radio Background toward Galaxy Clusters
S. A. Grebenev, R. A. Sunyaev
We explore the possibility of detecting the excess of the cosmic radio background (CRB) toward galaxy clusters due to its Compton scattering by electrons of the hot intergalactic g…
