| 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. |
