Quasar-mode feedback in nearby Type 1 quasars: ubiquitous kiloparsec-scale outflows and correlations with black hole properties.


Abstract (from CDS):

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 Type 1 radio-quiet quasars at z 0.3. The excellent image quality, coupled with a new technique to remove the point-spread function using spectral information, allows 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 hosts warm ionized and/or cool neutral outflows with spatially averaged velocities (<v_98 %_>≡<v+2σ >) of 200-1300 km s–1 and peak velocities (maximum v_98 %_) of 500-2600 km s–1. These minor-axis outflows are powered primarily by the central active galactic nucleus, 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 yr–1) and momentum boosts [(c dp/dt)/LAGN=0.01–20]. After extending the mass scale to Seyferts, dM/dt and dE/dt correlate with black hole mass (dM/dt∼MBH^0.7±0.3^ and dE/dt∼MBH^1.3±0.5^). Thus, the most massive black holes in the local universe power the most massive and energetic quasar-mode winds.
