Diagnosing holographic dark energy models with statefinder hierarchy
Jing-Fei Zhang, Jing-Lei Cui, Xin Zhang
We apply a series of null diagnostics based on the statefinder hierarchy to diagnose different holographic dark energy models including the original holographic dark energy, the ne…
Exploring the full parameter space for an interacting dark energy model with recent observations including redshift-space distortions: Application of the parametrized post-Friedmann approach
Yun-He Li, Jing-Fei Zhang, Xin Zhang
Dark energy can modify the dynamics of dark matter if there exists a direct interaction between them. Thus a measurement of the structure growth, e.g., redshift-space distortions (…
Revisiting the holographic dark energy in a non-flat universe: alternative model and cosmological parameter constraints
Jing-Fei Zhang, Ming-Ming Zhao, Jing-Lei Cui +1
We propose an alternative model for the holographic dark energy in a non-flat universe. This new model differs from the previous one in that the IR length cutoff is taken to be…
Measuring growth index in a universe with sterile neutrinos
Jing-Fei Zhang, Yun-He Li, Xin Zhang
Consistency tests for the general relativity (GR) can be performed by constraining the growth index using the measurements of redshift-space distortions (RSD) in conjunction wi…
Neutrinos and dark energy after Planck and BICEP2: data consistency tests and cosmological parameter constraints
Jing-Fei Zhang, Jia-Jia Geng, Xin Zhang
The detection of the B-mode polarization of the cosmic microwave background (CMB) by the BICEP2 experiment implies that the tensor-to-scalar ratio should be involved in the bas…
Effects of a time-varying color-luminosity parameter on the cosmological constraints of modified gravity models
Shuang Wang, Yong-Zhen Wang, Xin Zhang
It has been found that, for the Supernova Legacy Survey three-year (SNLS3) data, there is strong evidence for the redshift-evolution of color-luminosity parameter . In previous…
