The Difference between Radio-loud and Radio-quiet Active Galaxies

The recent development of unified theories of active galactic nuclei (AGN) has indicated that there are two physically distinct classes of these objects radio-loud and radio-quiet. The primary observational distinctions between the two types are: (1) The radio-loud objects produce large scale radio jets and lobes, with the kinetic power of the jets being a significant fraction of the total bolo...

Radio loud and radio quiet active galactic nuclei

We have generated a sample of 409 active galactic nuclei (AGNs) for which both the radio luminosity at 5 GHz and the line luminosity in [O III] j5007 have been measured. The radio luminosity spans a range of 10 orders of magnitude, and the [O III] line luminosity spans a range of 8 orders of magnitudeÈboth considerably larger than the ranges in previous studies. We show that these two quantitie...

Radio circular polarization of active galaxies

We present the first results of a circular polarization survey conducted with the Australia Telescope Compact Array (ATCA). We demonstrate the ability to make circular polarization measurements with a standard error of only 0.01 per cent, and have detections from both blazar and non-blazar active galactic nuclei (AGN). Our results show that, as a group, BL Lac sources and quasars have systemati...
