HST observations of 3C305.

Abstract

We present and discuss Hubble Space Telescope observations of the low-redshift radio galaxy 3C305 0.1" resolution images in [OII] and continuum bands are compared with VLA 2cm radio data. We quantify the radio-optical position offset in the northern lobe of the source and use this to constrain models of the interaction of radio jets with the ISM. A northern 1" scale continuum extension is found, almost perpendicular to the radio jet, and its significance discussed: we attribute the asymmetry to differential obscuration rather than beaming and scattering.
