A Double Radio Source with a Wide Component Separation

Abstract

Moffet (1964, 1965) has recently drawn attention to two double radio sources which have unusually large ratios of separation to component size. One of these, 3C 33, an interferometric double, has an angular separation of 250". and a component size of 16", giving a ratio of 16 : 1. The distance of the parent galaxy is such that the physical separation of the two components is at least 200 kpc. The other double consists of the sources 3C 343 and 3C 343·1 (revised Third Cambridge Catalogue
