摘要: We study the growth of linear perturbations induced by a generic causal scaling source as function cosmological parameters h, and . show that for wavenumbers k≳0.01 h Mpc−1 spectrum density velocity scales in similar way to found inflationary models with primordial perturbations. this result is independent more-or-less incoherent nature source, small-scale power deviations from naturally occur at late times if
