ON THE E/P-COSMIC RAYS AS MEDIATORS OF VISCOUS FORCES THAT CREATE SHOCK AND VORTEX STRUCTURES IN THE RADIO GALAXIES
Abstract
There are for the galaxies of FRII type (like Cygnus A) studied a number of hydrodynamic and kinetic processes to transport of magnetized plasma with cosmic rays, and a stratification process of RG-lobe because of e\p-cosmic rays. We found that the jet and bow shock in radio galaxies are supported by the processes of e\p-cosmic rays (acceleration, radiation), and the effects of changes in viscosity inside the cocoon. Cosmic rays are working inside the "jet head" into the cocoon stratification: to the light caviton (with high kinematic viscosity) and to the heavy shock cover (with high magnetic viscosity). The post-jet-vortex is injected by diffusion of e-rays through the area of "jet head" MHD-turbulized, and it is flowing a caviton around. Alternatively, the bow shock accompanied super sound turbulent waves and flows with p-rays.
