First Science with SAMI: A Serendipitously Discovered Galactic Wind in
  ESO 185-G031
  We present the first scientific results from the Sydney-AAO Multi-Object IFS
(SAMI) at the Anglo-Australian Telescope. This unique instrument deploys 13
fused fibre bundles (hexabundles) across a one-degree field of view allowing
simultaneous spatially-resolved spectroscopy of 13 galaxies. During the first
SAMI commissioning run, targeting a single galaxy field, one object (ESO
185-G031) was found to have extended minor axis emission with ionisation and
kinematic properties consistent with a large-scale galactic wind. The
importance of this result is two-fold: (i) fibre bundle spectrographs are able
to identify low-surface brightness emission arising from extranuclear activity;
(ii) such activity may be more common than presently assumed because
conventional multi-object spectrographs use single-aperture fibres and spectra
from these are nearly always dominated by nuclear emission. These early results
demonstrate the extraordinary potential of multi-object hexabundle spectroscopy
in future galaxy surveys.
