Heckman, T. M. ; Miley, G. K. ; Balick, B. ; van Breugel, W. J. M. ; Butcher, H. R. Abstract The results of a multiwavelength study of the radio galaxy 3C 305 are reported. Radio and optical imaging were employed, as well as slit spectroscopy. It was found that the morphologies and size scales of the radio and line-emitting regions were similar. Additionally, the radio polarization was negatively correlated with the presence of emission-line gas, which displayed a column density sufficient for Faraday depolarization of the radio continuum. The emission-line profiles covered the range 500-800 km/sec and were blue-asymmetric near the strong radio emission. Finally, emission-line gas detected seemed to be in an approximate pressure balance with the radio-emitting source and have kinetic energy close to the minimum energy of the synchrotron radio source. The emission line region is suggested to be powered by the radio jets' transfer of energy to the interstellar medium.
