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…
Time drift of cosmological redshifts as a test of the Copernican principle
Jean-Philippe Uzan, Chris Clarkson, George F. R. Ellis
We present the time drift of the cosmological redshift in a general spherically symmetric spacetime. We demonstrate that its observation would allow us to test the Copernican princ…
