Abstract
THE extended extragalactic radio sources1 are thought2,3 to be late stages in the evolution of relativistic plasma and magnetic fields ejected from galactic nuclei or quasistellar objects. The processes forming these sources, which may contain two or more components of emission in regions up to ≈300 kpc across, are not understood. Observations of their radio emission may, however, provide useful constraints on theories of their development (ref. 4, for example).
