dc.descriptionWe show that massive sterile neutrinos mixed with the ordinary ones may be produced in the early universe in the right amount to be natural warm dark matter particles. Their mass should be below 40 keV and the corresponding mixing angles sin^2 2θ> 10^{-11} for mixing with ν_μor ν_τ, while mixing with ν_e is slightly stronger bounded with mass less than 30 keV.
