Quasar-Mode Feedback in Nearby Type 1 Quasars: Ubiquitous Kiloparsec-Scale Outflows and Correlations with Black Hole Properties [GA]


The prevalence and properties of kiloparsec-scale outflows in nearby Type 1 quasars have been the subject of little previous attention. This work presents Gemini integral field spectroscopy of 10 $z<0.3$ Type 1 radio-quiet quasars. The excellent image quality, coupled with a new technique to remove the point spread function using spectral information, allow the fitting of the underlying host on a spaxel-by-spaxel basis. Fits to stars, line-emitting gas, and interstellar absorption show that 100% of the sample host warm ionized and/or cool neutral outflows with spatially-averaged velocities ($\langle v_{98\%} \rangle \equiv \langle v+2\sigma\rangle$) of 200-1300 km/s and peak velocities (maximum $v_{98\%}$) of 500-2600 km/s. These minor-axis outflows are powered primarily by the central AGN, reach scales of 3-12 kpc, and often fill the field of view. Including molecular data and Type 2 quasar measurements, nearby quasars show a wide range in mass outflow rates ($dM/dt = 1$ to $>$1000 M$\odot$/yr) and momentum boosts [$(c~dp/dt)/L\mathrm{AGN} = 0.01-20$]. After extending the mass scale to Seyferts, $dM/dt$ and $dE/dt$ correlate with black hole mass ($dM/dt \sim M_\mathrm{BH}^{0.7\pm0.3}$ and $dE/dt \sim M_\mathrm{BH}^{1.3\pm0.5}$). Thus, the most massive black holes in the local universe power the most massive and energetic quasar-mode winds.
