Unveiling the mass of the Universe: stars, gas, plasma and dark matter

使用独特的澳大利亚建造的光纤定位技术，该联谊会将测量到200万个星系的距离，改变我们对星系、星系群和细丝--存在的最大结构--尺度上的暗物质的理解。有两个具体目标：(I)通过基于测量到的前所未有的精度的星系运动建立暗物质晕星表来测试对主要冷暗物质模型的精确预测；以及(Ii)通过测量这些晕中的等离子体、中性气体和恒星含量的范围来解决长期存在的“丢失质量”的问题。这两个项目都将利用我们与欧洲南方天文台的战略接触。

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.
