Madsen, J. ; Epstein, R. I. Abstract The authors explore the possibility that the dark or missing matter in galaxies is due to massive neutrinos. Two approaches are described which give lower mass limits for a single neutrino type in terms of the observable properties of galaxies. In the first, the distribution of dark matter is compared to that of the most compact mass distribution which is possible for relic neutrinos. In the second, the deduced pressure for the dark matter in galaxies is compared with the equation of state for relic neutrinos. From the well studied galaxies M87 and M31 it is found that the neutrino mass must exceed 8 eV. The preliminary reports of dark matter in dwarf galaxies, if confirmed, would imply that the neutrino mass exceeds 125 eV.
