Query: Radio Luminosity Function, Importance of Jet Power, and Radio Properties
  of Nearby Low-Luminosity Active Galactic Nuclei   We present the completed results of a high resolution radio imaging survey of
all (around 200) low-luminosity active galactic nuclei (LLAGNs) in the Palomar
spectroscopic Sample of all (around 470) nearby bright northern galaxies. The
high incidence of pc-scale radio nuclei, with implied brightness temperatures
of the order of 10E7 K, and sub-parsec jets argue for accreting black holes in
50% of all LLAGNs; 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 extends three orders
of magnitude below, and is continuous with, that of "classical" AGNs.We find
marginal evidence for a low-power turnover in the RLF; nevertheless LLAGNs are
responsible for a significant fraction of accretion in the local universe. The
accretion energy output in LLAGNs is dominated by the energy in the observed
jets rather than the radiated bolometric luminosity. The Palomar LLAGNs follow
the same scaling between jet power and narrow line region (NLR) luminosity as
the parsec to kilo-parsec jets in powerful radio galaxies. Low accretion rates
(of 10E-2 to 10E-6 of the Eddington rate) are impliedin both advection- and
jet-type models, with evidence for increasing "radio-loudness" with decreasing
Eddington fraction. The jets are energetically more significant than supernovae
in the LLAGN host galaxies, and are potentially able to dump sufficient energy
into the innermost parsecs to significantly slow the accretion inflow. Detailed
results can be found in Nagar et al. (2002a) and Nagar et al. (2004, to appear
in Astronomy & Astrophysics).
