1. Observations of Molecular Outflows in Quasars Anna Boehle March 2 nd, 2012

2. Background merger driven galaxy evolution: – gas rich mergers -> starbursts and AGN activity – star-formation is quenched as gas is expelled – transition from blue to red what drives this negative feedback? – quasar (radiation pressure) – starburst (radiation pressure or winds from SNe)

3. Previous Observations Outflows seen in ionized gas – this is a small fraction of the total gas in the galaxy – molecular gas must be outflowing in order to quench star-formation Feruglio et al 2010 and Sturm et al 2011: observational evidence of molecular outflows

4. Feruglio et al 2010 observe CO(1-0) emission line Plateau di Bure Interferometer (PdBI) target: Mrk 231, nearest quasar object wider bandwidth (1 GHz) than previous CO observations!

5. Observed CO Emission Lines Fit Components: Broad, Narrow, Total Feruglio et al 2010

6. Spatial Maps Blue Wing -500 km/s -> -700 km/s Red Wing 500 km/s -> 800 km/s Feruglio et al 2010

7. Point Source Fit Residuals Blue Wing -500 km/s -> -700 km/s Red Wing 500 km/s -> 800 km/s Feruglio et al 2010

8. Sturm et al 2011 observe FIR spectra with PACS spectrometer on Herschel primary line used: OH 79 μm doublet targets shown here: – 5 ULIRGS with range of SFR and AGN contribution (including Mrk 231) – one starburst template (NGC 253)

9. OH 79 μm Doublet Sturm et al 2011

10. From Outflow Velocities to Mass Outflow Rates Rupke et al 20

11. What drives molecular outflows? v max of outflow versus Star Formation Rate v max of outflow versus AGN Luminosity Sturm et al 2011

12. What drives molecular outflows? Ṁ/SFR versus SFR Gas depletion time versus AGN luminosity Sturm et al 2011
