COBE-DMR-normalisation for Cosmological Constant Dominated Cold Dark Matter Models

Astrophysics 2009-09-25 v1

Abstract

The two-year COBE-DMR 53 and 90 GHz sky maps are used to determine the normalization of inflationary, cosmological constant dominated, cold dark matter models. Although the COBE-DMR data prefer a nearly critical value for the total density, low-density models with Omega_0 > 0.15 can not be rejected at a confidence level > 95%. We compare theoretical predictions for various large scale statistics, computed for a range of values of Omega_0 and h=0.5, or 0.8, to various measures of structure in the universe.
