Abstract

An observation of the source 1919 + 479 with the Westerbork Synthesis Radio Telescope (WSRT) at λ = 21 cm has shown it to have a remarkable morphology, probably that of a very unusual and very large wide angle tail radio galaxy. It is situated in a cluster of galaxies at an estimated redshift of 0.1. Although distortions of the morphology of radio sources caused by a cluster environment are well known, for example in producing normal head–tail and wide angle tail sources, the observed structure of 1919 + 479 is shown here to differ in several respects from previously known cluster sources.
