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.

A Little Hot Dark Matter Matters

Science, 1998
Astronomers believe that a large part of the mass in the universe is "dark." But what is the nature of this unseen mass? In his research commentary, Primack discusses results reported in the same issue by Gawiser and Silk in which several models of dark matter were examined.

The hot dark matter paradox

Nuclear Physics B - Proceedings Supplements, 2000
Abstract Direct observations favor a low-mass-density universe, but a critical density universe with a neutrino component of dark matter provides the best model for explaining the observed structure of the universe over more than three orders of magnitude in distance scale.

How Hot Is Dark Matter?

Science, 2012
Astronomers still don't know what the unseen "dark matter" is that provides the gravity that holds the galaxies together, but they may soon be able to narrow in on its most basic properties.
