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

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.
