Description

Mapping dark matter and testing gravity with galaxy surveys. This project aims to map the motions of vast numbers of galaxies to precisely measure the amount and distribution of dark matter and test Einstein’s theory of gravity. It will apply an innovative analysis to a major new galaxy survey using the Australian Square Kilometre Array Pathfinder and to other ongoing surveys. The outcome will be the most comprehensive and precise map to date of galaxies and their motions over most of the sky, tracing the growth of massive structures in the Universe and probing how gravity works on a cosmic scale. The project will leverage Australia’s investment in radio telescopes, address key priorities of the Astronomy Decadal Plan, train young researchers in data science, and enhance scientific links with Europe..
