Abstract

A simple cosmological model with only six parameters (matter density,mh 2, baryon density,bh 2, Hubble con-stant, H0, amplitude of fluctuations, 8, optical depth, , and a slope for the scalar perturbation spectrum, ns) fits not only the 3 yearWMAP temperature and polarization data, but also small-scale CMB data, light element abundances, large-scale structure observations, and the supernova luminosity/distance relationship.UsingWMAP data only, the best-fit values for cosmological parameters for the power-law flat cold dark matter (CDM) model are (mh
