We demonstrate a novel technology that combines the power of the multi-object spectrograph with the spatial multiplex advantage of an integral field spectrograph (IFS). The SydneyAAO (Australian Astronomical Observatory) Multi-object IFS (SAMI) is a prototype widefield system at the Anglo-Australian Telescope (AAT) that allows 13 imaging fibre bundles (‘hexabundles’) to be deployed over a 1-degree diameter field of view. Each hexabundle comprises 61 lightly fused multi-mode fibres with reduced cladding and yields a 75 per cent filling factor. Each fibre core diameter subtends 1.6 arcsec on the sky and each hexabundle has a field of view of 15 arcsec diameter. The fibres are fed to the flexible AAOmega double-beam spectrograph, which can be used at a range of spectral resolutions (R = λ/δλ ≈ 1700–13 000) over the optical spectrum (3700–9500 A). We present the first spectroscopic results obtained with SAMI for a sample of galaxies at z ≈ 0.05. We discuss the prospects of implementing hexabundles at a much higher multiplex over wider fields of view in order to carry out spatially resolved spectroscopic surveys of 10 4 –10 5 galaxies.

OBSERVING STRATEGY FOR THE SDSS-IV/MaNGA IFU GALAXY SURVEY (2015, methodology): “However, the two current wide-field, multi-object, IFS instruments–SAMI and MaNGA–use bare-fiber arrays to minimize cost while maximizing flexibility and patrol area, but at the penalty of not achieving truly integral spatial coverage at any one time.”

New fully empirical calibrations of strong-line metallicity indicators in star forming galaxies (2016, background): “In this way our calibrations could be in principle applied to a great variety of cases, in particular to large IFU galaxy surveys that allow spatially resolved abundance studies (e.g CALIFA, Sánchez et al. 2012, MaNGA, Bundy et al. 2015 or SAMI, Croom et al. 2012).”
