The Sydney-AAO Multi-object Integral field spectrograph

Abstract: 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 Sydney‐AAO (Australian Astronomical Observatory) Multi‐object IFS (SAMI) is a prototype wide‐field 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 y… Show more

“…These components are consistent with a photometric bulge-disk decomposition. Ideally such procedure could be carried out on large numbers of galaxies in forthcoming data releases of SAMI (Croom et al, 2012) and MaNGA (Bundy et al, 2014). However, its not clear that either survey has sufficient spatial or spectral resolution to apply this technique.…”

“…Recent advances now enable multiobject IFS with instruments such as SAMI (Croom et al 2012), KMOS (Sharples et al 2013), and MaNGA (Mapping Nearby Galaxies at Apache Point Observatory; Drory et al 2015). As a part of the 4th generation of the Sloan Digital Sky Survey (SDSS-IV), the MaNGA project bundles fibers from the Baryon Oscillation Spectroscopic Survey (BOSS) spectrograph (Smee et al 2013) into integral-field units (IFUs) to obtain spatially resolved optical spectroscopy of 10,000 nearby galaxies over a 6 year survey.…”

“…The reconstructed image of such unresolved objects can either look small and circular (if the object was centered on a single fiber), large and circular (if the object was centered in the interstitial gap between three fibers), highly elongated (if the object was centered midway between two fibers), along with any range of shapes in between. This is highly undesirable from a science standpoint, and therefore typical fiber-bundle IFU surveys (e.g., Croom et al 2012;Sánchez et al 2012) dither their observations. Small dithers of a fraction of the fiber spacing sample the missing points in the image plane and allow reconstructed images based on multiple, dithered exposures to achieve fairly uniform and integral spatial coverage.…”

“…For example, the Calar Alto Legacy Integral Field Area survey will obtain spatially resolved spectroscopic information for about 600 galaxies in the local universe, using integral field spectroscopy (Sánchez et al 2012). New imaging fiber bundles (so called hexabundles) are to be used on widefield survey telescopes (e.g., AAT; Bland-Hawthorn et al 2011;Croom et al 2012) to obtain spatially resolved stellar and gas kinematics for a volume-limited sample 10 4-5 galaxies. With such surveys it will be possible to study the AMD of galaxies in voids, filaments, groups, and clusters.…”
