Revolutionizing Our Understanding of AGN Feedback and its Importance to
  Galaxy Evolution in the Era of the Next Generation Very Large Array
  Energetic feedback by Active Galactic Nuclei (AGNs) plays an important
evolutionary role in the regulation of star formation (SF) on galactic scales.
However, the effects of this feedback as a function of redshift and galaxy
properties such as mass, environment and cold gas content remain poorly
understood. The broad frequency coverage (1 to 116 GHz), high sensitivity (up
to ten times higher than the Karl G. Jansky Very Large Array), and superb
angular resolution (maximum baselines of at least a few hundred km) of the
proposed next generation Very Large Array (ngVLA) are uniquely poised to
revolutionize our understanding of AGNs and their role in galaxy evolution.
Here, we provide an overview of the science related to AGN feedback that will
be possible in the ngVLA era and present new continuum ngVLA imaging
simulations of resolved radio jets spanning a wide range of intrinsic extents.
We also consider key computational challenges and discuss exciting
opportunities for multi-wavelength synergy with other next-generation
instruments, such as the Square Kilometer Array and the James Webb Space
Telescope. The unique combination of high-resolution, large collecting area,
and wide frequency range will enable significant advancements in our
understanding of the effects of jet-driven feedback on sub-galactic scales,
particularly for sources with extents of a few pc to a few kpc such as young
and/or lower-power radio AGNs, AGNs hosted by low-mass galaxies, radio jets
that are interacting strongly with the interstellar medium of the host galaxy,
and AGNs at high redshift.
