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…
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 initial conditions of the universe: how much isocurvature is allowed?
M. Bucher, J. Dunkley, P. G. Ferreira +2
We investigate the constraints imposed by the current data on correlated mixtures of adiabatic and non-adiabatic primordial perturbations. We discover subtle flat directions in par…
