Degenerate Fermions in Galaxy Clusters and Halos
51 Ch. des Maillettes, 1290 Sauverny, Switzerland
We explore the possibility that galaxy clusters or halos could be suited environments to host fermions like massive neutrinos in their degenerate state. Equilibrium density profiles for galaxy clusters and halos are calculated where the contribution of fermion particles to an isotropic collisionless component is taken into account. Fermions are supposed to cluster in CDM protoclusters while their phase space density is sufficient for not neglecting the Pauli's exclusion principle.
