Simulation of non-Gaussian CMB maps
Graca Rocha, M. P. Hobson, Sarah Smith +2
A simple method is presented for the rapid simulation of statistically-isotropic non-Gaussian maps of CMB temperature fluctuations with a given power spectrum and analytically-calc…
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…
Estimating the bispectrum of the Very Small Array data
Sarah Smith, Graca Rocha, Anthony Challinor +30
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtaine…
