Abstract

Cold + hot dark matter (CHDM) =1 cosmological models require a total neutrino mass 5 eV. Because recent data support the oscillation explanation of the cosmic ray deficit, which requires that m()m(), this suggests that m()m()2.4 eV. The linear calculations and N-body simulation reported here indicate that an =1 CHDM model with two 2.4 eV neutrinos (designated C2DM) agrees remarkably well with all available observations, but only if the Hubble parameter h0.5. We also show that even one 2.4 eV neutrino raises serious difficulties for low- flat CDM models. © 1995 The American Physical Society.
