We report from a study utilizing 3D MHD simulations, including cosmic-ray electrons, of the interactions between radio galaxies (RGs) and dynamically active intracluster media (ICMs). Here we consider interactions involving plane ICM shocks having Mach numbers 2-4 and their normals aligned with steady, active bipolar RG jets penetrating uniform, stationary ICMs. The shock impact disrupts the preformed RG jet cocoons into ring vortex structures. Sufficiently strong post-shock winds can stop and even reverse the upwind jet and strip jets to virtually naked states, leaving them without a surrounding cocoon. Strong shock-induced vorticity can also disrupt the downwind jet, so that the ring vortex remnant of the cocoons appears ahead of that jet's visible terminus. Magnetic field amplification in the ring vortex can significantly enhance its synchrotron emissions well after the vortex becomes isolated from the RG and its fresh cosmic-ray electron supply. We examine these dynamics and their observable consequences in detail.
