Prospects of detecting soft X-ray emission from typical WHIM filaments around massive clusters and the Coma cluster soft excess
E. Churazov, I. I. Khabibullin, K. Dolag +2
While hot ICM in galaxy clusters makes these objects powerful X-ray sources, the cluster's outskirts and overdense gaseous filaments might give rise to much fainter sub-keV emissio…
A snapshot of the oldest AGN feedback phases
M. Brienza, T. W. Shimwell, F. de Gasperin +19
Active Galactic Nuclei (AGN) inject large amounts of energy into their host galaxies and surrounding environment, shaping their properties and evolution. In particular, AGN jets in…
Tempestuous life beyond R_500: X-ray view on the Coma cluster with SRG/eROSITA. I. X-ray morphology, recent merger, and radio halo connection
E. Churazov, I. Khabibullin, N. Lyskova +2
This is the first paper in a series of studies of the Coma cluster using the SRG/eROSITA X-ray data obtained in course of the Calibration and Performance Verification observations.…
Strongly lensed SN Refsdal: refining time delays based on the supernova explosion models
Petr Baklanov, Natalia Lyskova, Sergei Blinnikov +1
We explore the properties of supernova (SN) "Refsdal" - the first discovered gravitationally lensed SN with multiple images. A large magnification provided by the galactic-scale le…
Progressive steepening of the SNR RX J1713.7-3946 X-ray spectrum from XMM-Newton to INTEGRAL
Ekaterina Kuznetsova, Roman Krivonos, Eugene Churazov +2
In this work, we present the first detailed analysis of the supernova remnant RX J1713.7-3946 in the hard X-ray energy range with the IBIS coded-mask telescope on board the INTEGRA…
Close-up view of an ongoing merger between the NGC 4839 group and the Coma cluster - a post-merger scenario
N. Lyskova, E. Churazov, C. Zhang +5
We study a merger of the NGC 4839 group with the Coma cluster using X-ray observations from the XMM-Newton and Chandra telescopes. X-ray data show two prominent features: (i) a lon…
