Large Scale Structure

The large scale structure of the Universe, as mapped by galaxy redshift surveys, offers a rich set of observable signatures for testing the cosmological model.  These include methods for measuring both the cosmic expansion history and the growth of structure, twin observables that are needed to discriminate between different physical scenarios for Dark Energy and constrain cosmological inflation through its effects on large-scale galaxy clustering.  This project follows in the strong Australian heritage in this area by conducting measurements of Baryon Acoustic Oscillations to constrain cosmic distances and expansion, using redshift-space distortions and voids in galaxy distributions to test theories of gravity, and density-field transformations to test non-linear growth of structure effects.
