We present the first results from Karl G. Jansky Very Large Array (VLA)
observations as a part of the Fundamental Reference Active Galactic Nucleus
(AGN) Monitoring Experiment (FRAMEx), a program to understand the relationship
between AGN accretion physics and wavelength-dependent position as a function
of time. With this VLA survey, we investigate the radio properties from a
volume-complete sample of 25 hard X-ray-selected AGNs using the VLA in its
wideband mode. We observed the targets in the A-array configuration at 4−12
GHz with all polarization products. In this work, we introduce our calibration
and imaging methods for this survey, and we present our results and analysis
for the radio quiet AGN NGC 4388. We calibrated and imaged these data using the
multi-term, multi-frequency synthesis imaging algorithm to determine its
spatial, spectral and polarization structure across a continuous 4−12 GHz
band. In the AGN, we measure a broken power law spectrum with α=−0.06
below a break frequency of 7.3 GHz and α=−0.34 above. We detect
polarization at sub-arcsecond resolution across both the AGN and a secondary
radio knot. We compare our results to ancillary data and find that the VLA
radio continuum is likely due to AGN winds interacting with the local
interstellar medium that gets resolved away at sub-parsec spatial scales as
probed by the Very Long Baseline Array. A well-known ionization cone to the
southwest of the AGN appears likely to be projected material onto the underside
of the disk of the host galaxy.Comment: 22 pages, 9 figures, Accepted in Ap
