I will summarize our extensive radio continuum polarimetric imaging study of the closest ultraluminous radio galaxy Cygnus A. These data are used to constrain models for relativistic particle acceleration and energy losses (Fermi acceleration and synchrotron aging), as well as to determine magnetic field strengths and morphologies in the radio source and in the surrounding intracluster medium. These data are also used to test jet theory for powering the double-lobed radio emitting structures. Issues addressed include: (i) relativistic jet origin, stability, confinement, composition, and velocity, (ii) the double shock structure for the jet terminus and the origin of multiple radio hot spots, (iii) the nature of filamentary structure in the radio lobes, and (iv) the hydrodynamic evolution of the radio lobes within a dense, hot cluster atmosphere, including an analysis of pressure balance between the various gaseous components. I will then use the conclusions from the Cygnus A study to infer physical conditions in the environments of ultraluminous radio galaxies at large cosmic look-back times.
