Models of inflation with primordial non-Gaussianities
Francis Bernardeau, Tristan Brunier, Jean-Philippe Uzan
We present a class of models in which the primordial metric fluctuations do not necessarily obey Gaussian statistics. These models are realizations of mechanisms in which non-Gauss…
The shape of high order correlation functions in CMB anisotropy maps
T. Brunier, F. Bernardeau
We present a phenomenological investigation of non-Gaussian effects that could be seen on CMB temperature maps. Explicit expressions for the temperature correlation functions are g…
Constraints on mode couplings and modulation of the CMB with WMAP data
Simon Prunet, Jean-Philippe Uzan, Francis Bernardeau +1
We investigate a possible asymmetry in the statistical properties of the cosmic microwave background temperature field and to do so we construct an estimator aiming at detecting a…
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…
