Abstract
We analyze the BOOMERANG and MAXIMA results in the context of simplest infl ationary universes verses: Omega (Total) = 1, n(s) similar or equal to 1. W e attempt to constrain three other parameters-h, Omega (B), and Omega (m)-f rom these observations. We show that (1) the data are consistent with the v alues of Omega (m) and h inferred from other observations and (2) the value of Omega (B)h(2) is too high to be compatible with big bang nucleosynthesi s observations at the 2 sigma level for n(s) = 1. We also include two cosmi c background imager (CBI) band powers in our analysis. However, the inclusi on of CBI band powers doesn't affect our conclusions.
