Multivariate Non-Normality in the WMAP 1st Year Data (2005)
The extraction of cosmological parameters from microwave background observations relies on specific assumptions about the statistical properties of the data, in particular that the p-point...
Peculiar Features in the Cosmic Microwave Background Radiation (2005)
In this thesis, I develop statistics capable of detecting peculiar features in current observations of the cosmic microwave background (CMB) radiation. Such tools scrutinise the very foundations of...

Non-Random Phases in Non-Trivial Topologies (2004)
Dineen, Patrick, Rocha, Graca, Coles, Peter
We present a new technique for constraining the topology of the universe. The method exploits the existence of correlations in the phases of the spherical harmonic coefficients of the CMB temperature...
Phase Correlations in Cosmic Microwave Background Temperature Maps (2003)
Coles, Peter, Dineen, Patrick, Earl, John, Wright, Dean
We study the statistical properties of spherical harmonic modes of temperature maps of the cosmic microwave background. Unlike other studies, which focus mainly on properties of the amplitudes of...
Faraday Rotation as a Diagnostic of Galactic Foreground Contamination of CMB Maps (2003)
We present a diagnostic test of possible Galactic contamination of cosmic microwave background sky maps designed to provide an independent check on the methods used to compile these maps. The method...
