Precision Prediction of the Log Power Spectrum

17 Dec 2016 Repp Andrew Szapudi István

At translinear scales, the log power spectrum captures significantly more cosmological information than the standard power spectrum. At high wavenumbers $k$, the Fisher information in the standard power spectrum $P(k)$ fails to increase in proportion to $k$ in part due to correlations between large- and small-scale modes...
