Radiative corrections to scalar masses in de Sitter space
T. Brunier, F. Bernardeau, J. -P. Uzan
We compute the radiative corrections to the mass of a test boson field in an inflating space-time. The calculations are carried out in case of a boson part of a supersymmetric chir…
Weak lensing in scalar-tensor theories of gravity
Carlo Schimd, Jean-Philippe Uzan, Alain Riazuelo
This article investigates the signatures of various models of dark energy on weak gravitational lensing, including the complementarity of the linear and non-linear regimes. It inve…
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…
The distance duality relation from X-ray and SZ observations of clusters
Jean-Philippe Uzan, Nabila Aghanim, Yannick Mellier
X-ray and Sunyaev-Zel'dovich data of clusters of galaxies enable to construct a test of the distance duality relation between the angular and luminosity distances. We argue that su…
Modulated fluctuations from hybrid inflation
Francis Bernardeau, Lev Kofman, Jean-Philippe Uzan
Inflation universally produces classical almost scale free Gaussian inhomogeneities of any light scalars. Assuming the coupling constants at the time of inflation depend on some li…
