Analytic Spectra of CMB Anisotropies and Polarization Generated by Relic Gravitational Waves with Modification due to Neutrino Free-Streaming
T. Y. Xia, Y. Zhang
We present an analytical calculation of the spectra of CMB anisotropies and polarizations generated by relic gravitational waves (RGWs). As a substantial extension to the previous…
Relic Gravitational Waves And CMB Polarization In The Accelerating Universe
Y. Zhang, W. Zhao, T. Y. Xia +2
In this paper we briefly present our works on the relic gravitational waves (RGW) and the CMB polarization in the accelerating universe. The spectrum of RGW has been obtained, show…
2-loop Quantum Yang-Mills Condensate as Dark Energy
T. Y. Xia, Y. Zhang
In seeking a model solving the coincidence problem, the effective Yang-Mills condensate (YMC) is an alternative candidate for dark energy. A study is made for the model up to the 2…
An exact analytic spectrum of relic gravitational waves in an accelerating universe
Yang Zhang, XinZhong Er, TianYang Xia +2
An exact analytic calculation is presented for the spectrum of relic gravitational waves in the scenario of accelerating Universe . The spectrum formula contains expli…
Numeric Spectrum of Relic Gravitational Waves in Accelerating Universe
Yang Zhang, Wen Zhao, Yefei Yuan +1
The accelerating expansion of the Universe at the present stage is a process that will change the spectrum of relic gravitational waves. Here we present a numerical calculation for…
