Small-scale anisotropy of microwave background radiation computed by means of the transfer function betweenz=2000 andz=800

Abstract

We use the transfer function betweenz=2000 andz=800, to compute the small-scale anisotropy of the microwave background radiation (MBR). Then the numerical input is minimized and most physical effects are computed on analytical bases. The different slopes of the spectrum are used to account for different mass scales. The numerical results show that the dependence of ΔT/T on the spectrum indexn is not monotonic but rather different for the two regimes ofn 2: forn 2 the curves with largern will go down. The highest curve corresponds ton=2.
