The radio and optical structure of 3C 66B.

Abstract

We report new, high-resolution radio observations of the jet in 3C 66B. The filaments in the optical jet seen in the HST image of Macchetto et al. are also visible in the radio image. The structure of the radio jet is complex and filamentary beyond the brightest knot. It is consistent with the HST image, which appears to consist of a central kinked tube containing oblique emission features, together with a surrounding shell of filaments. The radio-optical spectral index is remarkably constant along and across the jet.
