Prevalence of radio jets associated with quasar outflows and feedback
Abstract
We have identified that radio jets are commonly associated with ``radiative mode'' feedback in quasars. By performing a systematic multi-wavelength study of z < 0.2 quasars, we have found that 70-80% of our sample of `radio-quiet' type 2 quasars, which host kpc-scale ionized gas outflows, exhibit radio jet structures. Here, we discuss our results on the pilot sample of 10 objects that combine high resolution (~ 0.25 - 1 arcsec) radio imaging at 1-7 GHz with optical IFU observations. Our results demonstrate that it is extremely common for jets to be spatially and kinematically linked to kpc-scale ionized gas kinematics in such quasars. Therefore, radio jets may be an important driver of outflows during `radiative mode' feedback, apparently blurring the lines between the traditional divisions of feedback modes.
