Description:
Author(s): Francis Bernardeau, Nicolas Van de Rijt, and Filippo Vernizzi We use the so-called eikonal approximation, recently introduced in the context of cosmological perturbation theory, to compute power spectra for multicomponent fluids. We demonstrate that, at any given order in standard perturbation theory, multipoint power spectra do not depend on the large-scale a... [Phys. Rev. D 87, 043530] Published Tue Feb 26, 2013
