论文摘要
我们调查了最终Planck 2018 Legacy发行后最近引入的亚稳态暗能量（DE）模型。本工作的本质是在扰动水平上分析其演变。我们的分析表明，本文考虑的亚稳态暗能模型都是减轻$ H_0 $张力的绝佳候选者。特别是，对于目前的型号，仅普朗克2018即可减轻68 \％Cl的$ H_0 $张力。除了Planck 2018 Legacy版本中的最终宇宙微波背景数据外，我们还包括外部宇宙学数据集，以评估我们发现的鲁棒性。
We investigate the recently introduced metastable dark energy (DE) models after the final Planck 2018 legacy release. The essence of the present work is to analyze their evolution at the level of perturbations. Our analyses show that both the metastable dark energy models considered in this article, are excellent candidates to alleviate the $H_0$ tension. In particular, for the present models, Planck 2018 alone can alleviate the $H_0$ tension within 68\% CL. Along with the final cosmic microwave background data from the Planck 2018 legacy release, we also include external cosmological datasets in order to asses the robustness of our findings.
