Cosmological Hydrodynamic Simulations with Suppressed Variance in the Lyman- Forest Power Spectrum
Lauren Anderson, Andrew Pontzen, Andreu Font-Ribera +3
We test a method to reduce unwanted sample variance when predicting Lyman- (ly) forest power spectra from cosmological hydrodynamical simulations. Sample variance arises due…

Statistical properties of paired fixed fields
Francisco Villaescusa-Navarro, Sigurd Naess, Shy Genel +6
The initial conditions of cosmological simulations are commonly drawn from a Gaussian ensemble. The limited number of modes inside a simulation volume gives rise to statistical flu…
