Diffeomorphism-invariant averaging in quantum gravity and cosmology
Anthony W. H. Preston
This thesis concerns research undertaken in two related topics concerning high-energy gravitational physics. The first is the construction of a manifestly diffeomorphism-invariant…

Cosmological backreaction in higher-derivative gravity expansions
Anthony W. H. Preston
We calculate a general effective stress-energy tensor induced by cosmological inhomogeneity in effective theories of gravity where the action is Taylor-expandable in the Riemann te…

Cosmological back-reaction in modified gravity and its implications for dark energy
Anthony W. H. Preston, Tim R. Morris
We study the effective stress-energy tensor induced by cosmological inhomogeneity in and equivalent scalar-tensor theories, motivated both by models of early universe…
