Minimalist model of the W50/SS433 "Extended X-ray Jet": anisotropic wind with recollimation shocks

E. M. Churazov, I. I. Khabibullin, A. M. Bykov

W50 is a radio nebula around hyper-accreting Galactic microquasar SS~433. Here we focus on one peculiar feature of W50 - a pair of so-called "extended X-ray jets" (EXJs). These "je…

Weibel-dominated quasi-perpendicular shock: hybrid simulations and in situ observations

J. A. Kropotina, A. A. Petrukovich, O. M. Chugunova +1

We directly compare hybrid kinetic simulations and in situ observations of a high Mach number high- shock in the Solar wind. We launch virtual probes to demonstrate that the mod…

Discovery of a one-sided radio filament of PSR J0538+2817 in S147: escape of relativistic PWN leptons into surrounding supernova remnant?

Ildar Khabibullin, Eugene Churazov, Andrei Bykov +2

We report the discovery of a faint radio filament near PSR J0538+2817 in the NVSS, CGPS, and the Rapid ASKAP Continuum Survey data. This pulsar is plausibly associated with the sup…

X-ray emission from Westerlund 2 detected by SRG/ART-XC and Chandra: search for radiation of TeV leptons

A. M. Bykov, Yu. A. Uvarov, M. E. Kalyashova +5

We present the results of current observations of the young compact cluster of massive stars Westerlund 2 with the Mikhail Pavlinsky ART-XC telescope aboard the Spectrum-Roentgen-G…

Inside the core of a young massive star cluster: 3D MHD simulations

D. V. Badmaev, A. M. Bykov, M. E. Kalyashova

Young massive star clusters inhabit regions of star formation and play an essential role in the galactic evolution. They are sources of both thermal and non-thermal radiation, and…

High-resolution, High-sensitivity, Low-frequency uGMRT View of Coma Cluster of Galaxies

D. V. Lal, N. Lyskova, C. Zhang +12

We present high-resolution, high-sensitivity upgraded Giant Metrewave Radio Telescope observations of the Coma cluster (A1656) at 250-500 MHz and 550-850 MHz. At 250-500 MHz, 135 s…
