https://doi.org/10.1007/978-3-0348-5164-0s from the Parkes 11 cm catalog which are identified with galaxies of 17th magnitude or brighter in the declination zone -17° to -40°. Our objective is to cross-correlate the radio, infrared, optical, and other properties of a properly defined sample of radio galaxies.

The Spectral Index Distribution of Cygnus A,ce. Although both components show a steepening of spectral index away from the hotspots there is a marked asymmetry between the two components. This is interpreted as being due to a higher value of magnetic field in the S. component.

,Nuclear Ejection — One Side at a Time,n. The most likely explanation for the observed asymmetries is that ejection from the active nucleus occurs in only one direction at a time. This direction then switches back and forth to form the large scale double structures. Implications of this picture for the nuclear engine and the radio source environment are discussed.
