Information content in the halo-model dark-matter power spectrum
Mark C. Neyrinck, István Szapudi, Christopher D. Rimes
Using the halo model, we investigate the cosmological Fisher information in the non-linear dark-matter power spectrum about the initial amplitude of linear power. We find that ther…
Information content of the non-linear power spectrum: the effect of beat-coupling to large scales
C. D. Rimes, A. J. S. Hamilton
We measure the covariance of the non-linear matter power spectrum from N-body simulations using two methods. In the first case, the covariance of power is estimated from the scatte…
On measuring the covariance matrix of the nonlinear power spectrum from simulations
A. J. S. Hamilton, C. D. Rimes, R. Scoccimarro
We show how to estimate the covariance of the power spectrum of a statistically homogeneous and isotropic density field from a single periodic simulation, by applying a set of weig…
Information content of the non-linear matter power spectrum
C. D. Rimes, A. J. S. Hamilton
We use an ensemble of N-body simulations of the currently favoured (concordance) cosmological model to measure the amount of information contained in the non-linear matter power sp…
