Impact of Massive Neutrinos on the Nonlinear Matter Power Spectrum
Impact of Massive Neutrinos on the Nonlinear Matter Power Spectrum
We present the first attempt to analytically study the nonlinear matter power spectrum for a mixed dark matter model containing neutrinos of total mass $\ensuremath{\sim}0.1\text{ }\text{ }\mathrm{eV}$, based on cosmological perturbation theory. The suppression in the power spectrum amplitudes due to massive neutrinos is enhanced in the weakly nonlinear regime. …
