The dominant radio emission mechanism in radio-quiet quasars (RQQs) is anopen question. Primary contenders include: low-power radio jets, winds,star-formation and coronal emission. Our work suggests that radio polarizationand emission-line studies can help to distinguish between these scenarios anddetermine the primary contributor. Our multi-frequency, multi-scale radiopolarization study has revealed a composite jet and "wind" radio outflow in theradio-intermediate quasar, III Zw 2, as well as in the BALQSO, Mrk 231. Ourradio polarization study in conjunction with the [O III] emission-line study offive type 2 RQQs have provided insights on the interplay of jets/winds andemission-line gas. These sources reveal an anti-correlation between polarizedradio emission and [O III] emission. This is similar to that observed in someradio-loud AGN in the literature and suggests that the radio emission could bedepolarized by the emission-line gas. Overall, our work suggests that a closeinteraction between the radio outflow and the surrounding gaseous environmentis likely to be responsible for their stunted form in RQ and RI AGN.
