Radio-loud and radio-quiet active galactic nuclei

We have generated a sample of 409 active galactic nuclei (AGNs) for which b oth the radio luminosity at 5 GHz and the line luminosity in [O III] lambda 5007 have been measured. The radio luminosity spans a range of 10 orders o f magnitude, and the CO mi line luminosity spans a range of 8 orders of mag nitude-both considerably larger than the ranges in previous studies. We sho w that these two quantities are correlated in a similar way for both radio- loud and radio-quiet AGNs. We demonstrate that the observed correlation can be explained in terms of a model in which jets are accelerated and collima ted by a vertical magnetic field.
