Abstract:
Cosmic microwave background (CMB) anisotropies and density
fluctuations are calculated for flat cold dark matter (CDM) models
with a wide range of parameters, viz., {OMEGA}0,h, and {OMEGA}B,
for standard recombination and for various epochs of reionization.
Tables of the power spectrum of CMB anisotropies in the form of Cl
values as a function of l are presented. Although the
Harrison-Zeldovich initial spectrum is assumed in these tables, we
present simple approximations for obtaining the Cl values
corresponding to a tilted spectrum from those with a
Harrison-Zeldovich spectrum. Values of σ8 are derived for the
matter density spectrum, with σ(10deg), fixed Q_(rms-PS) and
COBE Differential Microwave Radiometer (DMR) 2yr normalizations.
Simple modifications of the fitting formula for the density transfer
function are given which are applicable for models with high baryon
density. By using both numerical results and these fitting formulae,
we calculate the relation between σ8 and Q_(rms-PS) and find
good agreement. In addition, the velocity fields are calculated.
Description:
The data are normalized to a sigma(10 deg) of 30 muK.
