Linearized Israel Matching Conditions for Cosmological Perturbations in a Moving Brane Background
Martin Bucher, Carla Carvalho
With a view toward the problem of computing the linearized cosmological perturbations in Randall-Sundrum cosmological models where a Z2 symmetry has been imposed about a boundary b…
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…
Models for the Brane-Bulk Interaction: Toward Understanding Braneworld Cosmological Perturbation
Pierre Binetruy, Martin Bucher, Carla Carvalho
Using some simple toy models, we explore the nature of the brane-bulk interaction for cosmological models with a large extra dimension. We are in particular interested in understan…
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…
