论文摘要
从理论上讲,动态暗能量(DDE)可能是对哈勃张力的可能解决方案。 To avoid the degeneracy between the Hubble parameter $H_0$ and the sound horizon scale $r_d$, in this article we use their multiplication as one parameter $c/\left(H_0 r_d\right)$ and we use it to infer cosmological parameters for 6 different models - $Λ$CDM and 5 DDE parametrizations -- the Chevallier-Polarski-Linder (CPL), the Barboza-Alcaniz(BA),低相关性(LC),Jassal-Bagla-Padmanabhan(JBP)和风潮模型。我们选择一个将此组合视为一个参数的数据集,其中包括Baryon声学振荡(BAO)数据$ 0.11 \ le Z \ le 2.40 $以及来自宇宙微波背景(CMB)峰的其他点($ z \ y $ z \ your z \ of 1090 $)。向他们添加边缘化的Pantehon数据集和GRB数据集。我们看到张力从$ h_0 $和$ r_d $移动到$ c/\ left(H_0 R_D \右)$和$ω_m$。只有一个模型满足Planck 2018在这两个参数上都有限制,这是LC的巨大错误。其余的不能适合这两个约束。相对于统计度量,$λ$ CDM是优选的。
It has been theorized that Dynamical Dark Energy (DDE) could be a possible solution to the Hubble tension. To avoid the degeneracy between the Hubble parameter $H_0$ and the sound horizon scale $r_d$, in this article we use their multiplication as one parameter $c/\left(H_0 r_d\right)$ and we use it to infer cosmological parameters for 6 different models - $Λ$CDM and 5 DDE parametrizations -- the Chevallier-Polarski-Linder (CPL), the Barboza-Alcaniz (BA), the Low correlation (LC), the Jassal-Bagla-Padmanabhan (JBP) and the Feng-Shen-Li-Li model. We choose a dataset that treats this combination as one parameter, that includes the Baryon Acoustic Oscillation (BAO) data $0.11 \le z \le 2.40$ and additional points from the Cosmic Microwave Background (CMB) Peaks ($z \approx 1090$). To them, we add the marginalized Pantehon dataset and GRB dataset. We see that the tension is moved from $H_0$ and $r_d$ to $c/\left(H_0 r_d\right)$ and $Ω_m$. There is only one model that satisfies the Planck 2018 constraints on both parameters and this is LC with a huge error. The rest cannot fit into both constraints. $Λ$CDM is preferred with respect to the statistical measures.
