Dark energy and neutrino mass constraints from weak lensing, supernova, and relative galaxy ages
Yan Gong, Tong-Jie Zhang, Tian Lan +1
We use the current weak lensing data to constrain the equation of state of dark energy and the total mass of massive neutrinos . The constraint on would be weak i…
Thermodynamical properties of dark energy with the equation of state
Yongping Zhang, Ze-Long Yi, Tong-Jie Zhang +1
The thermodynamical properties of dark energy are usually investigated with the equation of state . Recent observations show that our universe is accelerating, and…
Constraints on the DGP Universe Using Observational Hubble parameter
Hao-Yi Wan, Ze-Long Yi, Tong-Jie Zhang +1
In this work, we use observations of the Hubble parameter from the differential ages of passively evolving galaxies and the recent detection of the Baryon Acoustic Oscillations (BA…
Statefinder diagnostic for the modified polytropic Cardassian universe
Ze-Long Yi, Tong-Jie Zhang
We apply the Statefinder diagnostic to the Modified Polytropic Cardassian Universe in this work. We find that the Statefinder diagnostic is quite effective to distinguish Cardassia…
