Constraints on isocurvature models from the WMAP first-year data
K. Moodley, M. Bucher, J. Dunkley +2
We investigate the constraints imposed by the first-year WMAP CMB data extended to higher multipole by data from ACBAR, BOOMERANG, CBI and the VSA and by the LSS data from the 2dF…
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…
Fast and reliable MCMC for cosmological parameter estimation
Joanna Dunkley, Martin Bucher, Pedro G. Ferreira +2
Markov Chain Monte Carlo (MCMC) techniques are now widely used for cosmological parameter estimation. Chains are generated to sample the posterior probability distribution obtained…
The angular power spectrum of NVSS radio galaxies
Chris Blake, Pedro G. Ferreira, Julian Borrill
We measure the angular power spectrum of radio galaxies in the NRAO VLA Sky Survey (NVSS) using two independent methods: direct spherical harmonic analysis and maximum likelihood e…
