Gauge invariant cosmological perturbation theory for braneworlds
Alain Riazuelo, Filippo Vernizzi, Danièle Steer +1
We derive the gauge invariant perturbation equations for a 5-dimensional bulk spacetime in the presence of a brane. The equations are derived in full generality, without specifying…

Correlated mixtures of adiabatic and isocurvature cosmological perturbations
Alain Riazuelo, David Langlois
The Cosmic Microwave Background (CMB) anisotropies measurements can provide many clues about the Universe. Although the common belief is that they will allow a very precise measure…

Cosmic microwave background anisotropies seeded by coherent topological defects : a semi-analytic approach
Jean-Philippe Uzan, Nathalie Deruelle, Alain Riazuelo
We consider a perfectly homogeneous, isotropic and spatially flat universe which undergoes a sudden phase transition producing topological defects. We assume that these defects for…
