An optimal non-linear method for simulating relic neutrinos
An optimal non-linear method for simulating relic neutrinos
ABSTRACT Cosmology places the strongest current limits on the sum of neutrino masses. Future observations will further improve the sensitivity and this will require accurate cosmological simulations to quantify possible systematic uncertainties and to make predictions for non-linear scales, where much information resides. However, shot noise arising from neutrino thermal …
