Current observational constraints on holographic dark energy model
We consider the cosmological constraints on the holographic dark energy model by using the data set available from the type Ia supernovae (SNIa), CMB and BAO observations. The constrained parameters are critical to determine the quintessence or quintom character the model. The SNIa and joint SNIa+CMB+BAO analysis give the best-fit results for β with priors on Ωm0 and ω0. Using montecarlo we obt...
متن کاملGeneralized Interacting Holographic Dark Energy Model
In this manuscript, we present a generalization of the interacting holographic dark energy model using two equations of states for the dark energy: the modified variable Chaplygin gas and the viscous generalized Chaplygin gas. The dynamics of the model are expressed by the use of scalar fields and the scalar potentials. PACS numbers: 98.80.Cq, 98.80.-k, 98.80.Jk ∗[email protected]
متن کاملConstraints on holographic dark energy from Type Ia supernova observations
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 spatially flat FRW universe with matter component and holographic dark energy component. The fit result shows that the case c < 1 is favored, which implies that the holographic dark energy behaves as a quin...
متن کاملSupernova Constraints on a holographic dark energy model
In this paper, we use the type Ia supernova data to constrain the model of holographic dark energy. For d = 1, the best fit result is Ω0m = 0.25, the equation of the state of the holographic dark energy w Λ = −0.91 and the transition between the decelerating expansion and the accelerating expansion happened when the cosmological red-shift was zT = 0.72. If we set d as a free parameter, the best...
متن کاملInteracting holographic dark energy model in non - flat universe
We employ the holographic model of interacting dark energy to obtain the equation of state for the holographic energy density in non-flat (closed) universe enclosed by the event horizon measured from the sphere of horizon named L.
