Going Nonlinear with Dark Energy Cosmologies

Abstract

We propose an efficient method for generating high accuracy (~1%) nonlinear power spectra for grids of dark energy cosmologies. Our prescription for matching matter growth automatically matches the main features of the cosmic microwave background anisotropy power spectrum, thus naturally including ``CMB priors''.
