Power Spectrum Correlations Induced by Non-Linear Clustering

Abstract

Gravitational clustering is an intrinsically non-linear process that generates significant nonGaussian signatures in the density field. We consider how these affect power spectrum determinations from galaxy and weak-lensing surveys. Non-Gaussian effects not only increase the individual error bars compared to the Gaussian case but, most importantly, lead to… (More)
