Allison Kirkpatrick, Kirsten Hall, Kristina Nyland, Mark Lacy,, Isabella Prandoni

TL;DR
The paper proposes a wide-area, medium-depth ngVLA survey in the Stripe 82 field to detect and study the evolution of thousands of AGN, leveraging next-generation radio and multiwavelength data.
Contribution
It introduces a specific survey plan with detailed parameters to advance understanding of AGN evolution using the ngVLA.
Findings
Detection of ~130,000 galaxies including radio-quiet AGN up to z~7
Measurement of luminosity and space density evolution of AGN
Analysis of AGN clustering through cross-correlation functions
Abstract
The next generation Very Large Array (ngVLA) will have unprecedented sensitivities and mapping speeds at 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 survey in the Stripe 82 field using the 8 GHz band with an rms depth of Jy beam. We will detect 130,000 galaxies, including radio-quiet AGN out to . 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.
