Abstract: This papers describes three major scientific breakthroughs on galactic winds in the past year: (1) Our Herschel PACS GTO survey of ULIRGs (SHINING) has revealed far-infrared (FIR) OH features with P-Cygni profiles indicative of massive molecular outflows in several ULIRGs, including the closest quasar known, Mrk 231. (2) Independent, spatially resolved CO-emission observations of Mrk 231 with the IRAM/PdB mm-wave interferometer have confirmed this outflow and deduced mass outflow rates of about 700 yr-1, far larger than the on-going SFR (∼200 yr-1) in the host galaxy. Remarkably, this CO outflow coincides spatially with blueshifted optical Na ID 5890, 5896 A absorption features detected ∼2-3 kpc from the nucleus. (3) Our recent Gemini/IFU observations have revealed that the Na ID outflow is wide-angled, thus driven by a QSO wind rather than a jet. This powerful outflow may be the long-sought “smoking gun' of quasar mechanical feedback that clears out the molecular disk formed from dissipative collapse during the merger.
