Hector: a revolutionary survey machine to discover how galaxies formed. The formation of the Milky Way, is one of the most important questions in cosmology today. One of the key unknowns is how the gas, which forms the stars, gets into dark matter halos to make galaxies and why these galaxies spin. This project aims to assemble a first-rate instrument team to build Hector, the first automated hexabundle spectrograph; to assemble a large team to combine Hector's spectral imaging of 100,000 galaxies with new Australian radio observations; and to extend this technology for the Giant Magellan Telescope. This will help to ensure Australia's leadership in observational cosmology and instrumentation through this decade and into the era of extremely large telescopes.
