Quasar feedback survey: multiphase outflows, turbulence, and evidence for feedback caused by low power radio jets inclined into the galaxy disc

ABSTRACT We present a study of luminous, $z\, =\, 0.15$, type-2 quasar ($L_{[\rm O III]}$ = 1042.8 erg s−1) from the Quasar Feedback Survey. It is classified as ‘radio-quiet’ ($L_{\mathrm{1.4\, GHz}}$ 1023.8 W Hz−1); however, radio imaging reveals ∼ 1 kpc low-power jets (Pjet 1044 inclined into plane galaxy disc. combine MUSE and ALMA observations to map stellar kinematics ionized molecular gas properties. The are seen drive galaxy-wide bi-conical turbulent outflows, reaching W80 1000 – 1300 km s−1, in phase (traced via optical emission lines), which also have increased electron densities compared quiescent gas. driven perpendicular jet axis escaping along minor axis, 7.5 on both sides.
