Unraveling the Mystery of Dark Energy with Galaxy Clusters
Grant number: DP150103208 | Funding period: 2015 - 2019
The abundance of galaxy clusters, the most massive collapsed objects in the Universe, is exponentially sensitive to how structure forms. This project aims to discover massive galaxy clusters out to their redshift of formation in 2500 square degrees of sky using the Sunyaev-Zel'dovich effect. Galaxy clusters will be weighed using multi-frequency observations and the observed abundance of galaxy clusters will be used as a function of mass to address two fundamental questions in cosmology: what are the neutrino masses? and what is the nature of the dark energy that is driving the accelerating expansion of the Universe? The project will train young researchers in big data methods at the cutting ..View full description
