Abstract

The narrow emission line luminosities of radio-loud AGN arewell-correlated with their low-frequcncy radio luminosities. This correlationis linear and extends over at least four orders of magnitude. Thecorrelation is discussed in terms of a linear relationship between thepower in the radio-emitting jets and the photoionizing (i.e. accretion)luminosity. Support for this theory comes from a direct correlation betweenthe optical continuum and radio luminosities of steep-spectrumquasars. We discuss the dependence of the observed luminosities ofAGN on their black hole masses and how close to the Eddington limitthey are accreting.
