摘要

First light from the SAMI (Sydney-AAO Multi-object IFS) instrument at the Anglo-Australian Telescope (AAT) hasrecently proven the viability of fibre hexabundles for multi-IFU spectroscopy. SAMI, which comprises 13 hexabundleIFUs deployable over a 1 degree field-of-view, has recently begun science observations, and will target a survey ofseveral thousand galaxies. The scientific outputs from such galaxy surveys are strongly linked to survey size, leading thepush towards instruments with higher multiplex capability. We have begun work on a new instrument concept, calledHector, which will target a spatially-resolved spectroscopic survey of up to one hundred thousand galaxies. The keyscience questions for this instrument concept include how do galaxies get their gas, how is star formation and nuclearactivity affected by environment, what is the role of feedback, and what processes can be linked to galaxy groups andclusters. One design option for Hector uses the existing 2 degree field-of view top end at the AAT, with 50 individualrobotically deployable 61-core hexabundle IFUs, and 3 fixed format spectrographs covering the visible wavelength rangewith a spectral resolution of approximately 4000. A more ambitious option incorporates a modified top end at the AATwith a new 3 degree field-of-view wide-field-corrector and 100 hexabundle IFUs feeding 6 spectrographs.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
