Comparison of dark energy models: A perspective from the latest observational data
Miao Li, Xiao-Dong Li, Xin Zhang
In this paper, we compare some popular dark energy models under the assumption of a flat universe by using the latest observational data including the type Ia supernovae Constituti…
Probing interaction and spatial curvature in the holographic dark energy model
Miao Li, Xiao-Dong Li, Shuang Wang +2
In this paper we place observational constraints on the interaction and spatial curvature in the holographic dark energy model. We consider three kinds of phenomenological interact…
Interacting model of new agegraphic dark energy: Cosmological evolution and statefinder diagnostic
Li Zhang, Jinglei Cui, Jingfei Zhang +1
The statefinder diagnosic is a useful method for distinguishing different dark energy models. In this paper, we investigate the new agegraphic dark energy model with interaction be…
Reconstructing quintom from WMAP 5-year observations: Generalized ghost condensate
Jingfei Zhang, Yuan-Xing Gui
In the 5-year WMAP data analysis, a new parametrization form for dark energy equation-of-state was used, and it has been shown that the equation-of-state, , crosses the cosmo…
New Agegraphic Dark Energy in Brans-Dicke Theory
Xiang-Lai Liu, Xin Zhang
In this paper, we investigate the new agegraphic dark energy model in the framework of Brans-Dicke theory which is a natural extension of the Einstein's general relativity. In this…
Holographic dark energy models: A comparison from the latest observational data
Miao Li, Xiao-Dong Li, Shuang Wang +1
The holographic principle of quantum gravity theory has been applied to the dark energy (DE) problem, and so far three holographic DE models have been proposed: the original hologr…
