Description

Revealing the Unseen Universe with Gravitational Lensing. This project will analyse new Australian led observations from the Hubble Space Telescope of light being bent around massive galaxies by gravity. To analyse these images we must develop advanced physical models and statistical techniques. This analysis will give us highly magnified views of early galaxy evolution revealing physical details otherwise impossible to see. It will also allow us to put constraints on the nature of invisible dark matter with the possibility of detecting warm dark matter signatures and enable us to probe the expansion of the Universe, testing whether the unseen dark energy is evolving in time. The Hubble sample is much larger and a major advance on previous work, and enables breakthrough science in these areas.. Scheme: Discovery Projects. Field: 5101 - Astronomical Sciences.
