Using unique Australian-built fibre-positioning technologies, the Fellowship will measure the distances to 2 million galaxies, transforming our understanding of dark matter on the scales of galaxies, galaxy groups, and filaments – the largest structures that exist. There are two specific goals: (i) to test precise predictions of the leading cold dark matter model by constructing dark-matter halo catalogues based on the motions of galaxies measured to unprecedented accuracy; and (ii) to solve the long-standing "missing mass" problem by measuring the extent of the plasma, neutral gas, and stellar contents within these halos. Both programs will capitalise on our strategic engagement with the European Southern Observatory.

利用独特的澳大利亚制造的纤维定位技术，该奖学金将测量200万个星系的距离，改变我们在星系、星系群和细丝（现存最大的结构）尺度上对暗物质的理解。有两个具体目标：(i)通过构建暗物质晕目录，以前所未有的精度测量星系的运动，来测试对主要冷暗物质模型的精确预测；（ii）通过测量这些光晕内等离子体、中性气体和恒星含量的范围来解决长期存在的“缺失质量”问题。这两个项目都将利用我们与欧洲南方天文台的战略合作。
