Title: A Fitting Formula For The Effects Of Massive Neutrinos In The Nonlinear Regime
Author: Boriero D.
Abstract: The distribution of matter on small scales will be much better known in the next few years through upcoming surveys. To accomplish the measurement of parameters such as the neutrino mass, the accuracy of theoretical predictions must improve accordingly. We present an improved fitting formula for the matter power spectrum taking into account the effect of massive neutrinos in the nonlinear regime. The method used is a modified version of HALOFIT calibrated against N-body simulations with massive neutrinos.
