Radio properties of local AGN

This article focuses on the radio properties of the similar to 470 nearby bright (northern) galaxies of the Palomar spectroscopic sample. Almost half the sample's galaxies have nuclei with emission-lines characteristic of AGN but with L-H alpha = 50% of all LLAGNs; there is no evidence against all LLAGNs being mini-AGNs. The detected parsec-scale radio cores are almost exclusively found in massive ellipticals and in type I (i.e. with broad Ha emission) nuclei. These nuclei follow the usual correlations between radio and emission-line gas properties found in more powerful AGNs. The radio luminosity function (RLF) of Palomar Sample LLAGNs extends three orders of magnitude below, and is continuous with, that of 'classical' AGNs. We find marginal evidence for a low-end turnover in the RLF; nevertheless LLAGNs axe responsible for a significant fraction of accretion in the local universe. Low accretion rates
