Cosmic microwave background bispectrum on small angular scales
Cyril Pitrou, Jean-Philippe Uzan, Francis Bernardeau
This article investigates the non-linear evolution of cosmological perturbations on sub-Hubble scales in order to evaluate the unavoidable deviations from Gaussianity that arise fr…
Predictions from an anisotropic inflationary era
Cyril Pitrou, Thiago S. Pereira, Jean-Philippe Uzan
This article investigates the predictions of an inflationary phase starting from a homogeneous and anisotropic universe of the Bianchi I type. After discussing the evolution of the…
Theory of cosmological perturbations in an anisotropic universe
Thiago S. Pereira, Cyril Pitrou, Jean-Philippe Uzan
This article describes the theory of cosmological perturbations around a homogeneous and anisotropic universe of the Bianchi I type. Starting from a general parameterisation of the…
