The Largest Scale We Can Detect in the Universe and the Inflation
Wen Zhao, Yang Zhang
From the damping of the Cosmic Microwave Background Radiation (CMB) anisotropy power spectrum at large scale and the recent accelerating expansion of the Universe, we find that, th…
The State Equation of the Yang-Mills field Dark Energy Models
Wen Zhao, Yang Zhang
In this paper, we study the possibility of building Yang-Mills(YM) field dark energy models with equation of state (EoS) crossing -1, and find that it can not be realized by the si…
CMB Temperature Anisotropy Quadrupole Generated by Tensor Perturbation

Analytic approach to the CMB polarizations generated by relic gravitational waves
Wen Zhao, Yang Zhang
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 t…
Relic Gravitational Waves in the Accelerating Universe
Yang Zhang, Yefei Yuan, Wen Zhao +1
Observations have recently indicated that the Universe at the present stage is in an accelerating expansion, a process that has great implications. We evaluate the spectrum of reli…
