3C236, DA240; the largest radio sources known

Abstract

A high resolution study has been made of faint and very extensive radio components associated with the galaxies 3C236 and DA240. Their respective linear dimensions of 5.7 Mpc and 2 Mpc are without precedent. Their properties are compared with those of other radio galaxies and the consequences for present models of the evolution of these objects are briefly discussed.
