SAMI (Sydney university AAO MOS IFU) has the potential to
revolutionise our understanding of galaxies, with spatially-resolved
spectroscopy of large numbers of targets. It is the first on-sky application
of innovative photonic imaging bundles called hexabundles, which will remove
the aperture effects that have biased previous multi-fibre astronomical
surveys. SAMI was installed at the AAT in July 2011 and is being commissioned.
I will discuss the instrument design, present some early commissioning results on
our first galaxy targets, and outline the SAMI galaxy survey science.
