Scientific paper

An optical linear polarization map of the galaxy associated with the powerful radio source Cygnus A (z = 0.0566) is presented. The centro- symmetric pattern of polarization orientations in the central double structure shows strong similarities with the patterns observed in galactic bipolar nebulae, and provides confirmation that a component of the central area of Cygnus A is a 'giant reflection nebula', as originally proposed by Pierce & Stockton. We use the polarization measurements to show that the nucleus of Cygnus A would look much brighter if observed from along the radio axis, thus providing support for unified schemes for AGN. We also show that the power and spectral energy distribution of the nucleus are consistent with the idea that a large fraction of the anisotropy of the radiation field is due to obscuration by a dusty disc, although the data do not exclude contributions from other collimation mechanisms (e.g. relativistic beaming).
