Alleviation of Cosmic Age Problem In Interacting Dark Energy Model
Shuang Wang, Yang Zhang
We investigate the cosmic age problem associated with the old high- quasar APM 08279 + 5255 and the oldest globular cluster M 107, both being difficult to accommodate in CDM…
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…
A Coarse-Grained Field Theory for Density Fluctuations and Correlation Functions of Galactic Objects
Yang Zhang
We present a coarse-grained field theory of density fluctuations for a Newtonian self-gravitating many-body system and apply it to a homogeneous Universe with small density fluctua…
Relic gravitational waves and their detection
Wen Zhao, Yang Zhang
As the strong evidence for inflation, the relic gravitational waves (RGW) have been extensively studied. Although, it has not been detected, yet some constraints have been achieved…
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…
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…
