Evolution of Power Spectrum in Non-Gaussian Models
Abstract
Evolution of power spectrum is studied for non-Gaussian models of structure formation. We generalize the dark-matter-approach to these models and find that the evolved spectrum at weakly nonlinear regime is mainly determined by a simple integral of the dark-matter-halo mass function in this approach. We also study the change of the nonlinear spectrum within the current observational constraint of the primordial non-Gaussianity.
