|Title:||SAMI Galaxy Survey: Spectral Mapping of Galaxies by the Dozen|

SAMI deploys 13 photonic integral field units across 1 deg diam. FOV at
the AAT prime focus to feed the AAOmega double-beam spectrograph. It is
a common-user supported instrument available to all AAO users worldwide.
For the past 3.5 years it has been used primarily for the SAMI Galaxy
Survey (SGS, sami-survey.org/papers) led by Prof. Scott Croom (U.
Sydney) to map 3400 galaxies over 15 arcsec diam. at ~2 arcsec
resolution out to z=0.1. Spectra over 320-700 nm are recorded
up to R=4500. Extensive multi-band ancillary data are available from the
GAMA Survey, but the SGS also targets some clusters. I will
review some SAMI insights on gaseous and stellar kinematics, shock
excitation, and star formation. The first 900 galaxies will be in
public DR1 by year’s end.
