| Summary:
We present the third phase of the largest high-frequency, high-resolution
imaging survey of 231 nearby, hard X-ray selected AGN, with a very high $98 pm
1%$ detection fraction. This survey presents VLA 22 GHz radio observations
with 1" spatial resolution covering over $6$ orders of magnitude in radio
luminosity in nearby AGN that span $sim4$ orders of magnitude in black hole
mass and X-ray luminosity. We identify three different radio morphologies: $44
pm 3%$ (102/231) are compact or unresolved, $46 pm 3%$ (106/231) show an
extended structure (star formation, possible one-sided jets, etc.), and $8 pm
2%$ (19/231) have a biconical or two-sided jet-like morphology. The remaining
$2 pm 1%$ (4/231) sources are non-detections. The radio-to-X-ray luminosity
ratios of the Swift-BAT AGN ($text{L}_R/text{L}_{14-195 text{keV}} sim
10^{-5.5}$ and $text{L}_R/text{L}_{2-10 text{keV}} sim 10^{-5}$) with a
scatter of $sim0.5$ dex are similar to that of coronally active stars
($text{L}_R/text{L}_X sim 10^{-5}$). For most targets, extended emission in
radio-quiet objects is broadly consistent with the expectation for star
formation from previous FIR observations, once the contribution from the radio
core has been subtracted. Our sample represents nearby analogs of distant AGN
at the peak of black hole growth, and thus the high detection fraction in our
work has important implications for future high frequency AGN radio surveys
with the next generation VLA (ngVLA) or Square Kilometre Array (SKA), both of
which should detect large fractions of more distant AGN.
