EDITORIAL: Highlight Notes on "Do non-relativistic neutrinos constitute the dark matter?"

Treumann, R.A. (2009), EDITORIAL: Highlight Notes on "Do non-relativistic neutrinos constitute the dark matter?", Europhysics Letters, 86(5), 50000, doi:10.1209/0295-5075/86/50000.

Abstract
Matter in the Universe seems to be made up to a large fraction of the so-called dark matter, the consistence of which is unknown. Searches for dark-matter particles have so far not been successful. The general belief is that they are Weakly Interacting and Massive Particles, the so-called WIMPs. The present paper uses the experimentally determined excess mass contrast of one particular cluster of galaxies (Abell 1689) fitting its radial dependence under the assumption of a thermal fermionic contribution. This yields an active fermionic mass m = 1.45 eV which is compared with different particle families and their cosmological evolution. Agreement is obtained for 3 non-relativistic massive-neutrino families which would constitute the cluster dark matter. Such massive non-relativistic neutrinos could indeed be cosmological, not causing contradiction with well-accepted cosmological evolutionary scenarios. They would condensate on the cluster at redshift z ~ 28 and would actively contribute to re-ionise the intracluster gas. This observation revives the previously abandoned neutrinos as viable dark-matter candidates at least for the Giant Cluster Abell 1689.
