Cosmological Constraints from Hubble parameter and SN Ia observations
Hui Lin, Cheng Hao, Xiao Wang +4
In this paper, we use a set of observational data (OHD) to constrain the CDM cosmology. This data set can be derived from the differential ages of the passively evolving…
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…
Constraints on holographic dark energy models using the differential ages of passively evolving galaxies
Ze-Long Yi, Tong-Jie Zhang
Using the absolute ages of passively evolving galaxies observed at different redshifts, one can obtain the differential ages, the derivative of redshift with respect to the cos…
Constraint on Cosmological Model with Matter Creation Using Complementary Astronomical Observations
Yuan Qiang, Tong-Jie Zhang, Ze-Long Yi
The universe with adiabatic matter creation is considered. It is thought that the negative pressure caused by matter creation can play the role of a dark energy component, and driv…
