Non-parametric Dark Energy Degeneracies
Renée Hlozek, Marina Cortês, Chris Clarkson +1
We study the degeneracies between dark energy dynamics, dark matter and curvature using a non-parametric and non-perturbative approach. This allows us to examine the knock-on bias…
A general test of the Copernican Principle
Chris Clarkson, Bruce A. Bassett, Teresa Hui-Ching Lu
The recent discovery of apparent cosmic acceleration has highlighted the depth of our ignorance of the fundamental properties of nature. It is commonly assumed that the explanation…
Dynamical Dark Energy or Simply Cosmic Curvature?
Chris Clarkson, Marina Cortes, Bruce A. Bassett
We show that the assumption of a flat universe induces critically large errors in reconstructing the dark energy equation of state at z>~0.9 even if the true cosmic curvature is ve…
On the Observational Characteristics of Inhomogeneous Cosmologies: Undermining the Cosmological Principle
Chris A. Clarkson
This thesis concerns the compatibility of inhomogeneous cosmologies with our present understanding of the universe. It is a problem of some interest to find the class of all relati…
