Phys. Rev. D 71, 125009 (2005) [5 pages]Neutrino mass limit from galaxy cluster number density evolutionReceived 15 March 2005; published 15 June 2005 Measurements of the evolution with redshift of the number density of massive galaxy clusters are used to constrain the energy density of massive neutrinos and so the sum of neutrino masses ∑mν. We consider a spatially flat cosmological model with cosmological constant, cold dark matter, baryonic matter, and massive neutrinos. Accounting for the uncertainties in the measurements of the relevant cosmological parameters we obtain a limit of ∑mν<2.4 eV (95% C.L.). © 2005 The American Physical Society URL:
