This project aims to deliver the first part of Hector, an instrument that can produce three-dimensional (3D) images of 60,000 galaxies in 5 years. This is an improvement on the SAMI instrument at the Anglo-Australian Telescope, which obtains spectroscopy at 61 contiguous positions across each galaxy and provides information about stars and gas in each galaxy. The massive amount of 3D data obtained over this 5-year survey will unlock secrets about how spinning galaxies like our own form. This cosmological survey of the local universe is expected to reveal how galaxies, including the Milky Way, evolve and build up their spin with cosmic time. Spin-off technologies could have important industrial applications outside astronomy.

该项目旨在提供Hector的第一部分，这是一种可以在5年内产生60，000个星系的三维（3D）图像的仪器。这是对英澳望远镜SAMI仪器的改进，SAMI仪器在每个星系的61个相邻位置获得光谱，并提供有关每个星系中恒星和气体的信息。在这项为期5年的调查中获得的大量3D数据将揭开像我们这样的星系如何旋转的秘密。这项对本地宇宙的宇宙学调查有望揭示包括银河系在内的星系如何随着宇宙时间演化和建立它们的自旋。附带技术可在天文学之外具有重要的工业应用。
