Science with an ngVLA: Accreting Supermassive Black Holes in Nearby
  Low-mass Galaxies
  The ngVLA will facilitate deep surveys capable of detecting the faint and
compact signatures of accreting supermassive black holes (SMBHs) with masses
below one million solar-masses hosted by low-mass ($< 10^9$ solar-masses)
galaxies. This will provide important new insights on both the origins of
supermassive black holes and the possible impact of active galactic
nucleus-driven feedback in a currently unexplored mass regime.
