Scientific paper

The authors study the linear evolution of adiabatic density fluctuations in a model with dark matter made of two kinds of collisionless particles, both relativistic at their decoupling. The mass variance δM/M, the rms large-scale peculiar velocity fields, and the microwave radiation small-scale anisotropies are derived. Agreement with observations is found for a primeval spectral index n = 1, assuming δM/M = 10-14.5M_sun; today, with nonlinear effects starting at z ≈ 6. To lower such redshift, either n ≈ 0.5 or a biased galaxy formation or both are required.
