K stat'e "Small-scale fluctuations of relict radiation"

Diagram of gravitational instability in the "big-bang" model. The region of instability is located to the right of the line MJ(t); the region of stability to the left. The two additional lines of the graph demonstrate the temporal evolution of density perturbations of matter: growth until the moment when the considered mass is smaller than the Jeans mass and oscilations thereafter. It is apparent that at the moment of recombination perturbations corresponding to different masses correspond to different phases.

The dependence of the square of the amplitude of density perturbations of matter on scale. The fine line designates the usually assumed dependence (). It is apparent that fluctuations of relict radiation should depend on scale in a similar manner.
