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…
Random-Walk Statistics and the Spherical Harmonic Representation of CMB Maps
Andrew Stannard, Peter Coles
We investigate the properties of the (complex) coefficients obtained in a spherical harmonic representation of temperature maps of the cosmic microwave background (CMB). We study t…
Large-scale Structure with the SKA
Peter Coles
A standard theoretical paradigm for the formation of large-scale structure in the distribution of galaxies has now been established, based on the gravitational instability of cold…
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…
