Radio galaxies are known to inflate lobes of hot relativistic plasmas into the intergalactic medium. Here we present hydrodynamical and magnetohydrodynamical simulations these plasma bubbles in FRII objects. We focus on later stages their evolution after jet has died down bow shock that surrounded at earlier vanished. investigate as they become subject Rayleigh-Taylor instabilities. From our calculate radio X-ray emissivities discuss appearance observations. Finally, influence large-scale magnetic fields bubbles. The issues re-acceleration diffusion particles briefly discussed.
