Constraints on holographic dark energy from X-ray gas mass fraction of galaxy clusters
Zhe Chang, Feng-Quan Wu, Xin Zhang
We use the Chandra measurements of the X-ray gas mass fraction of 26 rich clusters released by Allen et al. to perform constraints on the holographic dark energy model. The constra…
Constraints on holographic dark energy from type Ia supernova observations
Xin Zhang, Feng-Quan Wu
In this paper, we use the type Ia supernovae data to constrain the holographic dark energy model proposed by Li. We also apply a cosmic age test to this analysis. We consider in th…
Statefinder diagnostic for holographic dark energy model
Xin Zhang
In this paper we study the holographic dark energy model proposed by Li from the statefinder viewpoint. We plot the evolutionary trajectories of the model with in the statefi…
Statefinder diagnostic for coupled quintessence
Xin Zhang
The problem of the cosmic coincidence is a longstanding puzzle. This conundrum may be solved by introducing a coupling between the two dark sectors. In this Letter, we study two ca…
Coupled Quintessence in a Power-Law Case and the Cosmic Coincidence Problem
Xin Zhang
The problem of the cosmic coincidence is a longstanding puzzle. This conundrum may be solved by introducing a coupling between the two dark sectors. In this Letter, we study a coup…
