Abstract | |||||||||||||
| . This paper covers several techniques of intercomparison of Cosmic Microwave Background (CMB) anisotropy experiments and models of structure formation. It presents the constraints on several cosmological parameters using current CMB observations. 1. Introduction In 1964 Penzias and Wilson [143] discovered the Cosmic Microwave Background (CMB) radiation as an excess instrument noise with temperature 3K, coming from all directions in the sky. Dicke and Peebles et al. (1965) [57] interpreted this as the relic radiation from the Big Bang. The discovery of this relic radiation in conjunction with Hubble's observation of the cosmic expansion in 1927 [100], the synthesis of the light elements, the evolution of radio source counts etc, provided strong support to the hot Big Bang model. Recently the FIRAS instrument on the COBE satellite has confirmed that this radiation has a Planck spectrum with [133]: T0 = 2:726 \Sigma 0:010K (95% confidence): (1) In the standard Big Bang model thermal... | |||||||||||||
