Dark energy and dark matter are amongst the most profound puzzles facing fundamental physics. This Laureate Fellowship aims to measure and explain the dark side of the universe by performing new theoretical analyses of
two groundbreaking surveys. The Dark Energy Survey will discover approximately 3000 supernovae. The Dark Energy Spectroscopic Instrument will measure distances to 30 million galaxies. This project will combine these to determine whether dark energy changes with time, narrow the search for a quantum theory of gravity, and complete the standard model of particle physics by measuring the mass of the neutrino, while positioning Australia to play a pivotal leadership role in future international cosmology.
