An ngVLA Wide Area AGN Survey
  The next generation Very Large Array (ngVLA) will have unprecedented
sensitivities and mapping speeds at $1-8$ GHz. We discuss how the active
galactic nuclei (AGN) community can benefit from a wide-area, medium depth
ngVLA survey. We propose a 10 deg$^2$ survey in the Stripe 82 field using the 8
GHz band with an rms depth of $1\,\mu$Jy beam$^{-1}$. We will detect
$\sim$130,000 galaxies, including radio-quiet AGN out to $z\sim7$. We can
measure the luminosity and space density evolution of radio-quiet and
radio-loud AGN. We can also measure AGN evolution through clustering of both
populations using cross-correlation functions. A wide area ngVLA survey will
benefit from existing multiwavelength AGN populations, particularly in the
Stripe 82 field, as well as new information from next-generation optical and
infrared survey instruments such as LSST and WFIRST.
