[103.07] The radio properties of radio-quiet quasars

M. J. Kukula (STScI), J. Dunlop, D. Hughes (U. Edinburgh), S. Rawlings (U. Oxford)

Although radio-quiet quasars (RQQs) are by no means radio silent the properties of their radio emission are as yet only poorly understood. We present the results of a multi-frequency VLA study of 27 low-redshift RQQs. In general, we find that the properties of the radio sources in RQQs are consistent with them being weak, small-scale (\sim 1 kpc) jets similar to, but more powerful than, those observed in nearby Seyfert galaxies. We conclude that a significant fraction of the radio emission in RQQs is directly associated with the central engine and is not a result of stellar processes in the surrounding galaxy. We also find evidence for a direct correlation between optical and radio luminosity in RQQs and Seyfert Galaxies.
