Dark neutrinos as Cold Dark Matter

Astroparticle Physics, 2015
Abstract It is shown that heavy sterile neutrinos can be a consequence of a new broken U(1)X symmetry. This sterile symmetry is further speculated to be related to the conservation of the dark number associated with Dark Matter particles, corresponding to a dark neutrino mass m N D ⩾ 1 keV with a high scale ⩾ ∼ 10

Cold + Hot Dark Matter

Nuclear Physics B - Proceedings Supplements, 1995
The Cold + Hot Dark Matter (CHDM) model appears to require about 5 eV of neutrino mass in order to produce early enough galaxy formation. Recent experimental data suggests that this neutrino mass may be divided between two species of neutrinos, each with mass of about 2.4 eV.

Cold dark matter

1999
Abstract The processes by which stars and planetary systems form from interstellar gas clouds, and by which galaxies form from protogalactic gas clouds, are among the most intractable in modern physics. We know a great deal about general relativity, black holes, particle physics, the evolution of the universe.
