Radio Sources in Low-Luminosity Active Galactic Nuclei. IV. Radio Luminosity Function, Importance of Jet Power, and Radio Properties of the Complete Palomar Sample Nagar N.M., Falcke H., Wilson A.S. <Astron. Astrophys. 435, 521 (2005)> =2005A&A...435..521N

The high incidences of pc-scale radio nuclei, with implied brightness temperatures ≳10^7K, and sub-parsec jets argue for accreting black holes in ≥50% of all LINERs and low-luminosity Seyferts; there is no evidence against all LLAGNs being mini-AGNs. The detected parsec-scale radio nuclei are preferentially found in massive ellipticals and in type 1 nuclei (i.e. nuclei with broad Halpha emission). The radio luminosity function (RLF) of Palomar Sample LLAGNs and AGNs extends three orders of magnitude below, and is continuous with, that of 'classical' AGNs. We find marginal evidence for a low-luminosity turnover in the RLF; nevertheless LLAGNs are responsible for a significant fraction of present day mass accretion. Description: Results of VLA and VLBA radio imaging of low-luminosity active galactic nuclei (LLAGNs) and AGNs in the Palomar sample are presented in these two on-line tables (both tables are also available in the printed version). Table 1: Table 1 lists the results of high resolution VLA radio imaging for all Palomar sample LLAGNs and AGNS. Columns 1 to 4 are listed for all Palomar AGNs and LLAGNs. For nuclei in our survey, all relevant columns are listed. For data taken from the literature, only a few of the relevant columns are filled and the remaining data can be found in the corresponding reference (last column of the table). Table 2: Table 2 lists the results of VLBA/VLBI observations for all LLAGNs and AGNs in the Palomar sample observed with the VLBA/VLBI . All relevant columns are listed for nuclei observed by us. Only a few of the relevant columns are filled for data taken from the literature; full data on these nuclei are available in the corresponding references (last column of the table). File Summary:
