The Quasar Feedback Survey: revealing the interplay of jets, winds, and emission-line gas in type 2 quasars with radio polarization

ABSTRACT 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 5 GHz Hubble Space Telescope (HST) [O iii] observations. These sources are known to exhibit close association between structures ionized gas morphology kinematics. Four (J0945+1737, J1000+1242, J1356+1026, J1430+1339) show in current data. J1010+1413 is unpolarized source our sample. detect $0.5{-}1{{\ \rm per\ cent}}$ fractional cores high ($10{-}30{{\ cent}}$) lobes these sources. The morphological, spectral, properties suggest jet origin for emission J0945+1737, J1010+1413, J1430+1339 whereas data cannot fully discern (jet or wind) J1356+1026. An anticorrelation various polarized knots observed sources, similar that some radio-loud AGN literature. This suggests likely be depolarized by gas. By modelling depolarization effects, we estimate size clouds ∼(2.8 ± 1.7) × 10−5 parsec amount thermal material mixed synchrotron plasma ∼(1.01 0.08) 106 M⊙ lobe J0945+1737 (which exhibits most prominent signature its lobe). work demonstrates interplay jets/winds responsible nature outflows radio-quiet AGN.
