Constraints from Ly-α forests on non-thermal dark matter including resonantly-produced sterile neutrinos
We use BOSS DR9 quasars to constrain 2 cases of dark matter models: cold-plus-warm (C+WDM) where the warm component is a thermal relic, and sterile neutrinos resonantly produced in the presence of a lepton asymmetry (RPSN). We establish constraints on the relic mass m_x and its relative abundance $F=\Omega_{wdm}/\Omega_{dm}$ using …
