Journal ArticleDOI
Simulating the Fermi Bubbles as Forward Shocks Driven by AGN Jets
Ruiyu Zhang,Fulai Guo +1 more
TL;DR: In this paper, a suite of hydrodynamic simulations were used to study the scenario where the cosmic rays (CRs) in the bubbles are mainly accelerated at the forward shocks driven by a pair of opposing jets from Sgr A*.
Journal ArticleDOI
Are the hotspots of radio galaxies the sites of in situ acceleration of relativistic particles
Gopal-Krishna,Prasad Subramanian,Prasad Subramanian,Paul J. Wiita,Paul J. Wiita,Peter A. Becker +5 more
TL;DR: In this paper, the authors examined the basic question of whether the detection of optical synchrotron radiation requires in situ acceleration of relativistic electrons within the hotspots/lobes.
Journal ArticleDOI
Non-thermal radio emission from O-type stars. 2. HD 167971
TL;DR: In this article, the authors observed the radio emission of HD 167971 with the Very Large Array (VLA) and the Australia Telescope Compact Array (ATCA) and constructed a radio lightcurve covering a 20-yr time-range.
Journal ArticleDOI
Instabilities of a multicomponent plasma with accelerated particles and magnetic field generation in astrophysical objects
Andrei M. Bykov,Igor N. Toptygin +1 more
TL;DR: In this paper, a system of MHD equations for the description of a magnetized nonequilibrium astrophysical plasma with neutral atoms and suprathermal (in particular, relativistic) particles is formulated.

On the radio spectra of supernova remnants
TL;DR: In this article, the theoretical fundamentals of formation of the supernova remnant (SNR) continuum radio spectra are presented in a review, which can represent some kind of "atlas" with initial patterns for the different kinds of SNR radio spectrum.
