全息暗能量模型的当前观测约束

Current observational constraints on holographic dark energy model

L. N. Granda, W. Cardona, A. Oliveros

摘要:

利用Ia型超新星、CMB和BAO观测数据,研究了全息暗能量模型的宇宙学约束.约束参数是决定模型的本质或特征的关键. SNIa和联合SNIa+CMB+BAO分析给出了$β$与$Ω_{m0}$和$ω_0$先验的最佳拟合结果。使用蒙特卡洛,我们获得了$β$、$Ω_{m0}$和$ω_0$的最佳拟合值。的statefinder和$Om$诊断已被用来表征其他DE模型的模型。

英文摘要:

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 $Ω_{m0}$ and $ω_0$. Using montecarlo we obtained the best-fit values for $β$, $Ω_{m0}$ and $ω_0$. The statefinder and $Om$ diagnosis have been used to characterize the model over other DE models.
