ASKAP discovery of a 30 kpc bipolar outflow from the edge-on disk of the nearby spiral galaxy ESO 130-G012
Baerbel S. Koribalski, Roland M. Crocker, Ildar Khabibullin +6
We present the discovery of a large-scale, limb-brightened outflow, extending at least 30 kpc above and below the star-forming disk of the edge-on galaxy ESO 130-G012 (D = 16.9 Mpc…
Detection of Compton scattering in the jet of 3C 84
Ioannis Liodakis, Sudip Chakraborty, Frédéric Marin +77
3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low frequency radi…
Simulating the LOcal Web (SLOW) -- VI: Gamma-ray Emission in the Local Universe
Ludwig M. Böss, Ildar Khabibullin, Daniel Karner +4
Context: Diffuse -ray emission from cosmic-ray (CR) protons scattering off the gas in the intracluster and intergalactic medium remains out of reach for current observations. De…
X-ray panorama of the SS433/W50 complex by SRG/eROSITA
Rashid Sunyaev, Ildar Khabibullin, Eugene Churazov +3
The Galactic microquasar SS 433 and the radio nebula W50 surrounding it present a prototypical example of a hyper-Eddington binary system shaping its ambient interstellar medium vi…
PeV particle acceleration and non-thermal emission in the `minimalist' model of the extended jets in W50/SS433
A. M. Bykov, S. M. Osipov, V. I. Romansky +3
The W50 nebula around microquasar SS~433, powered by supercritical accretion, features two `extended jets' (tens of pc long and a few pc wide) from which polarized X-ray and very h…
XRISM observations of solar flare X-ray emission reflected in the Earth's atmosphere
Hiromasa Suzuki, Jun Kurashima, Koji Mori +13
The X-ray Imaging and Spectroscopy Mission (XRISM), launched into low-Earth orbit in 2023, observes the reflection of solar flare X-rays in the Earth's atmosphere as a by-product o…
X-ray flux -- mass relation for galaxy clusters
Natalia Lyskova, Eugene Churazov, Ildar Khabibullin +3
We use a subsample of co-detections of the ACT and MaDCoWS cluster catalogs to verify the predicted relation between the observed X-ray flux in the 0.5-2~keV band and the clu…
Polarization of reflected X-ray emission from the Sgr A molecular complex: multiple flares, multiple sources?
Ildar Khabibullin, Eugene Churazov, Riccardo Ferrazzoli +100
The extended X-ray emission observed in the direction of several molecular clouds in the central molecular zone of our Galaxy exhibits spectral and temporal properties consistent w…
Cosmological Zoom-In Simulation of Odd Radio Circles as Merger-Driven Shocks in Galaxy Groups
Anna Ivleva, Ludwig M. Böss, Klaus Dolag +2
Odd Radio Circles (ORCs) are a new class of distinct radio objects that has recently been discovered. The origin of these features is yet unclear because their peculiar properties…
Two intersecting radio shells: relics of galaxy merger shocks ?
Bärbel S. Koribalski, Klaus Dolag, Ildar Khabibullin +3
We present the discovery of two intersecting radio shells, likely radio relics, surrounding a compact galaxy group dominated by a massive elliptical galaxy. The shells present as p…
Fast and "lossless" propagation of relativistic electrons along magnetized non-thermal filaments in galaxy clusters and the Galactic Center region
Eugene Churazov, Lawrence Rudnick, Ildar Khabibullin +3
Relativistic leptons in galaxy clusters lose their energy via radiation (synchrotron and inverse Compton losses) and interactions with the ambient plasma. At z~0, pure radiative lo…
Perseus cluster in its X-ray entirety with SRG/eROSITA. Merger and Radio-Uroboroses
Eugene Churazov, Ildar Khabibullin, Natalya Lyskova +2
The Perseus cluster (Abell 426) is a nearby massive galaxy cluster that spans several degrees. We combined SRG/eROSITA, XMM-Newton, and Chandra data to get a complete coverage of t…
X-ray investigation of the remarkable galaxy group Nest200047
Anwesh Majumder, A. Simionescu, T. Plšek +11
Galaxy groups are more susceptible to feedback from the central active galactic nuclei (AGN) due to their lower gravitational binding energy compared to clusters. This makes them i…
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…
Limits and challenges of the detection of cluster-scale diffuse radio emission at high redshift: The Massive and Distant Clusters of WISE Survey (MaDCoWS) in LoTSS-DR2
G. Di Gennaro, M. Brüggen, E. Moravec +14
Diffuse radio emission in galaxy clusters is a tracer of ultra-relativistic particles and G-level magnetic fields, and is thought to be triggered by cluster merger events. In th…
Non-thermal filaments and AGN recurrent activity in the galaxy group Nest200047: a LOFAR, uGMRT, MeerKAT, VLA radio spectral analysis
M. Brienza, K. Rajpurohit, E. Churazov +15
Nest200047 is a clear example of multiple radio bubbles from an Active Galactic Nucleus (AGN) in a galaxy group, featuring non-thermal filaments likely shaped by buoyancy, gas moti…
