Analytic approach to the CMB polarizations generated by relic gravitational waves
By Polnarev’s method we analytically calculate the polarization spectra of the cosmic microwave background radiation (CMB) generated by cosmic relic gravitational waves (RGW). In this analytic approach the physics involved in this generating process is more transparent. Consequently, the effects due to various elements of physics can be isolated easily. In solving the equation for evolution of ...

متن کاملAn Analytic Approach to the Polarization of the Cosmic Microwave Background Generated by Relic Gravitational Waves
We develop the Polnarev’s analytic method to calculate of the polarization power spectrum of the cosmic microwave background radiation (CMB) due to relic gravitational waves. This approach complements the more precise numerical results by providing insight into the physical origins of the features in the power spectrum. We make use of the WKB approach to handle the evolution of the relic gravit...

متن کاملApproximate Analytic Spectra of Reionized CMB Anisotropies and Polarization generated by Relic Gravitational Waves
We present an approximate, analytical calculation of the reionized spectra C l of cosmic microwave background radiation (CMB) anisotropies and polarizations generated by relic gravitational waves (RGWs). Three simple models of reionization are explored, whose visibility functions are fitted by gaussian type of functions as approximations. We have derived the analytical polarization βl and tempe...
