Cosmic microwave background radiation

In particular, we will show that the studied models really admit the Bianchi type I metrics, which are homogeneous but anisotropic space time, as their stable cosmological solutions. Hence, these models turn out to be counterexamples to the cosmic no-hair conjecture.

The Cosmic Microwave Background (CMB) radiation from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite mission (14) is one of the main sources of data about the early universe. Deciphering the CMB in terms of the density perturbations, gravity wave polarization, power spectrum and its various indices is a formidable task. It also requires the heavy CMB mathematical formalism based on General Relativity — see eg., the textbooks (17–19).
