High order correlation functions for self interacting scalar field in de Sitter space
Francis Bernardeau, Tristan Brunier, Jean-Philippe Uzan
We present the expressions of the three- and four-point correlation functions of a self interacting light scalar field in a de Sitter spacetime at tree order respectively for a cub…
Finite volume effects for non-Gaussian multi-field inflationary models
Francis Bernardeau, Jean-Philippe Uzan
Models of multi-field inflation exhibiting primordial non-Gaussianity have recently been introduced. This is the case in particular if the fluctuations of a light field scalar fiel…
Cosmic microwave background anisotropies in multi-connected flat spaces
Alain Riazuelo, Jeffrey Weeks, Jean-Philippe Uzan +2
This article investigates the signature of the seventeen multi-connected flat spaces in cosmic microwave background (CMB) maps. For each such space it recalls a fundamental domain…
Dodecahedral space topology as an explanation for weak wide-angle temperature correlations in the cosmic microwave background
J. -P. Luminet, J. Weeks, A. Riazuelo +2
Cosmology's standard model posits an infinite flat universe forever expanding under the pressure of dark energy. First-year data from the Wilkinson Microwave Anisotropy Probe (WMAP…
WMAP data and the curvature of space
Jean-Philippe Uzan, Ulrich Kirchner, George F. R. Ellis
Inter alia, the high precision WMAP data on Cosmic Microwave Background Radiation marginally indicate that the universe has positively curved (and hence spherical) spatial sections…
Cosmic microwave background constraints on multi-connected spherical spaces
Jean-Philippe Uzan, Alain Riazuelo, Roland Lehoucq +1
This article describes the Cosmic Microwave Background anisotropies expected in a closed universe with the topology of a lens space L(p,q) and with density parameter Omega_0 close…
