  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. Given its unique combination of frequency range, angular
resolution, and sensitivity, the ngVLA will serve as a transformational new
tool in our understanding of how radio jets affect their surroundings. By
combining broadband continuum data with measurements of the cold gas content
and kinematics, the ngVLA will quantify the energetic impact of radio jets
hosted by gas-rich galaxies as the jets interact with the star-forming gas
reservoirs of their hosts.
