Combined constraints on modified Chaplygin gas model from cosmological observed data: Markov Chain Monte Carlo approach
Jianbo Lu, Lixin Xu, Yabo Wu +1
We use the Markov Chain Monte Carlo method to investigate a global constraints on the modified Chaplygin gas (MCG) model as the unification of dark matter and dark energy from the…
CDM Model as a Unified Origin of Holographic and Agegraphic Dark Energy Models
Yun Chen, Zong-Hong Zhu, Lixin Xu +1
Motivated by the fact that any nonzero can introduce a length scale or a time scale into Einstein's theory, . Conversely, any cosmological length scale o…
Constraints on the generalized Chaplygin gas model including gamma-ray bursts via a Markov Chain Monte Carlo approach
Nan Liang, Lixin Xu, Zong-Hong Zhu
We investigate observational constraints on the generalized Chaplygin gas (GCG) model including the gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 type…
Constraints on modified Chaplygin gas from recent observations and a comparison of its status with other models
Jianbo Lu, Lixin Xu, Jiechao Li +3
In this Letter, a modified Chaplygin gas (MCG) model of unifying dark energy and dark matter with the exotic equation of state is constrained…
Cosmological constraints on generalized Chaplygin gas model: Markov Chain Monte Carlo approach
Lixin Xu, Jianbo Lu
We use the Markov Chain Monte Carlo method to investigate a global constraints on the generalized Chaplygin gas (GCG) model as the unification of dark matter and dark energy from t…
The Integrated Sachs-Wolfe Effect in Time Varying Vacuum Model
Yuting Wang, Yuan-Xing Gui, Lixin Xu +1
The integrated Sachs-Wolfe (ISW) effect is an important implication for dark energy. In this paper, we have calculated the power spectrum of the ISW effect in the time varying vacu…
