Mixed Cold-Hot Dark Matter Model with several Massive Neutrino Types

Journal In: Large Scale Structure in the Universe (Proc. of the 11th Potsdam Workshop on Relativistic Astrophysics, Potsdam, 19-24 Sept. 1994), eds. J.P. Mücket, S. Gottlöber, V. Müller, World Scientific (Singapore), 1995, pp. 118-122

AbstractMixed cold-hot dark matter cosmological models (CHDM) with $Omega_{tot}=1$, approximately flat initial spectrum of adiabatic perturbations and 1, 2 or 3 types of massive neutrinos are compared and tested using recent observational data. The models with 2 or 3 neutrino types of equal mass permit as the best fit larger values of both the Hubble constant ($H_0le 60$ for 2 types, $H_0le 65$ for 3 types) and the total $Omega_{ u}$ (up to 0.3 for 3 types) than the model with 1 massive type. Also, they have less problems with abundances of early compact objects including $Ly-alpha$ clouds.
