This project aims to build new understanding about the fundamental physics behind how galaxies get their gas. The way gas is accreted in galaxies affects how stars are made and what galaxies look like, including our own milky way. This project expects to build a new robotic instrument for three dimensional spectroscopy of galaxies, called Hector-I, to establish and run the Hector Galaxy Survey, the largest of its kind ever conducted. This survey data set will underpin broad investigations of gas accretion and the impact on the physical properties of galaxies. The project will clarify why our own galaxy looks so different to others, demonstrate Australian technologies for future commercialisation on international facilities, and train students for a high quality workforce.

该项目旨在对星系如何获得气体背后的基本物理学建立新的理解。气体在星系中的吸积方式影响着恒星的形成和星系的样子，包括我们的银河系。该项目预计将建立一个新的机器人仪器，用于星系的三维光谱学，称为赫克托-I，以建立和运行赫克托星系调查，这是有史以来最大的一次。这一调查数据集将支持对气体吸积和对星系物理性质影响的广泛调查。该项目将阐明为什么我们自己的星系看起来与其他星系如此不同，展示澳大利亚未来在国际设施上商业化的技术，并培养学生成为高素质的劳动力。
