Abstract: (arXiv)
Cold + Hot Dark Matter (CHDM) cosmological models require a total neutrino mass eV. Because recent data support the oscillation explanation of the cosmic ray deficit, which requires that , this suggests that eV. The linear calculations and N-body simulation reported here indicate that an CHDM model with two 2.4 eV neutrinos (designated CDM) agrees remarkably well with all available observations, but only if the Hubble parameter . We also show that even one 2.4 eV neutrino raises serious difficulties for low- flat CDM models.- cosmological model
