Science with an ngVLA: The Sunyaev-Zeldovich Effect from Quasar and
  Starburst Winds
  The Sunyaev-Zeldovich Effect (SZE) can be used to detect the hot bubbles in
the intergalactic medium blown by energetic winds from AGN and starbursts. By
directly constraining the kinetic luminosity, age and total energy of the
outflow, it offers the promise of greatly increasing our understanding of the
effects of wind feedback on galaxy evolution. Detecting the SZE in these winds
is very challenging, at the edge of what is possible using existing facilities.
The scale of the signal (10-100 kpc) is, however, well matched to
interferometers operating at mm wavelengths for objects at z~1. Thus this could
become a major science area for the ngVLA, especially if the design of the core
is optimized for sensitivity on angular scales of >1 arcsec in the 90 GHz band.
