The Quasar Feedback Survey: Revealing the Interplay of Jets, Winds \&
  Emission Line Gas in Type 2 Quasars with Radio Polarization
  We present results from a combined radio polarization and emission line study
of five type 2 quasars at $z<0.2$ with the Karl G. Jansky Very Large Array
(VLA) B-array at 5 GHz and Hubble Space Telescope (HST) [O~{\sc{iii}}]
observations. These five sources are known to exhibit close association between
radio structures and ionized gas morphology and kinematics. Four sources
(J0945+1737, J1000+1242, J1356+1026 and J1430+1339) show polarization in the
current data. J1010+1413 is the unpolarized source in our sample. We detect
$0.5-1\%$ fractional polarization in the radio cores and a high fractional
polarization ($10-30\%$) in the lobes of these sources. The morphological,
spectral and polarization properties suggest a jet origin for radio emission in
J0945+1737, J1000+1242, J1010+1413 and J1430+1339 whereas the current data
cannot fully discern the origin of radio emission (jet or wind) in J1356+1026.
An anti-correlation between various polarized knots in the radio and
[O~{\sc{iii}}] emission is observed in our sources, similar to that observed in
some radio-loud AGN in the literature. This suggests that the radio emission is
likely to be depolarized by the emission-line gas. By modeling the
depolarization effects, we estimate the size of the emission-line gas clouds to
be $\sim(2.8\pm1.7)\times10^{-5}$ parsec and the amount of thermal material
mixed with the synchrotron plasma to be $\sim(9.2\pm0.8)\times10^{5}$~M$_\odot$
in the lobe of J0945+1737 (which exhibits the most prominent polarization
signature in its lobe). The current work demonstrates that the interplay of
jets/winds and emission-line gas is most likely responsible for the nature of
radio outflows in radio-quiet AGN.
