Description

I will present a dark matter model in which the dark matter particle is a fermion with mass about 200 eV. In this mass range the Fermi pressure can solve the core-cusp problem of the dwarf galaxies and the Lyman-alpha constraints can be avoided by cooling and scattering in the dark sector.
