Approximate Analytic Spectra of Reionized CMB Anisotropies and Polarization generated by Relic Gravitational Waves
T. Y. Xia, Y. Zhang
We present an approximate, analytical calculation of the reionized spectra of cosmic microwave background radiation (CMB) anisotropies and polarizations generated by rel…
