Multivariate Non-Normality in the WMAP 1st Year Data
Patrick Dineen, Peter Coles
The extraction of cosmological parameters from microwave background observations relies on specific assumptions about the statistical properties of the data, in particular that the…
A Faraday Rotation Template for the Galactic Sky
Patrick Dineen, Peter Coles
Using a set of compilations of measurements for extragalactic radio sources we construct all-sky maps of the Faraday Rotation produced by the Galactic magnetic field. In order to g…
Non-Random Phases in Non-Trivial Topologies
Patrick Dineen, Graca Rocha, Peter Coles
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…
Phase Correlations in Cosmic Microwave Background Temperature Maps
Peter Coles, Patrick Dineen, John Earl +1
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 th…
Faraday Rotation as a Diagnostic of Galactic Foreground Contamination of CMB Maps
Patrick Dineen, Peter Coles
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 thes…
