We perform a global fit study on the new agegraphic dark energy (NADE) model in a non-flat universe by using the MCMC method with the full CMB power spectra data from the WMAP 7-yr observations, the SNIa data from Union2.1 sample, BAO data from SDSS DR7 and WiggleZ Dark Energy Survey, and the latest measurements of H0 from HST. We find that the value of Ωk0 is greater than 0 at least at the 3σ confidence levels (CLs), which implies that the NADE model distinctly favors an open universe. Besides… 
Revisiting the interacting model of new agegraphic dark energy
In this paper, a new version of the interacting model of new agegraphic dark energy (INADE) is proposed and analyzed in detail. The interaction between dark energy and dark matter is reconsidered.
Agegraphic dark energy: growth index and cosmological implications
We study the main cosmological properties of the agegraphic dark energy model at the expansion and perturbation levels. Initially, using the latest cosmological data we implement a joint likelihood
Comparison of dark energy models after Planck 2015
We make a comparison for ten typical, popular dark energy models according to their capabilities of fitting the current observational data. The observational data we use in this work include the JLA
Searching for a preferred direction with Union2.1 data
A cosmological preferred direction was reported from the Type Ia supernovae data in recent years. We use the Union2.1 data to give a simple classification of such studies for the first time. Because
New agegraphic dark energy model with the sign-changeable interaction
In this paper, we investigate a cosmological model with the sign-changeable interaction between new agegraphic dark energy (NADE) and dark matter. By analysis it is shown that the equation of state
Prospect for constraining holographic dark energy with gravitational wave standard sirens from the Einstein Telescope
We study the holographic dark energy (HDE) model by using the future gravitational wave (GW) standard siren data observed from the Einstein Telescope (ET) in this work. We simulate 1000 GW standard
New agegraphic dark energy model in Brans-Dicke theory with logarithmic form of scalar field
In this paper, the cosmological evolution of new agegraphic dark energy (NADE) model is analyzed in Brans-Dicke theory within the framework of Friedmann-Robertson-Walker Universe. The power-law
Diagnosing holographic type dark energy models with the Statefinder hierarchy, composite null diagnostic and w-w′ pair
The main purpose of this work is to distinguish various holographic type dark energy (DE) models, including the ΛHDE, HDE, NADE, and RDE model, by using various diagnostic tools. The first diagnostic

Interacting model of new agegraphic dark energy: observational constraints and age problem
Many dark energy models fail to pass the cosmic age test because of the old quasar APM 08279+5255 at redshift z = 3.91, the ΛCDM model and holographic dark energy models being no exception. In this
Constraints on Dark Energy Parameters from Correlations of CMB with LSS
In this paper, we combine the the latest observational data, including the WMAP five-year data (WMAP5), the baryon acoustic oscillations (BAO) and type Ia supernovae (SN) ``union" compilation, and
Comparison of dark energy models: A perspective from the latest observational data
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 Constitution compilation, the baryon
Examining the evidence for dynamical dark energy.
TLDR
Estimates of the Bayesian evidence show little preference between the cosmological constant model and the dynamical model for a range of correlated prior choices, and it is found that the best fit models for current data could be well distinguished from the ΛCDM model by observations such as Planck and Euclid-like surveys.

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 this paper a
