In this article we compare a variety of well known dynamical dark energy models using the cosmic microwave background measurements from the 2018 Planck legacy and 2015 Planck data releases, the baryon acoustic oscillations measurements and the local measurements of H0 obtained by the SH0ES (Supernovae, H0, for the Equation of State of Dark energy) collaboration analysing the Hubble Space Telescope data. We discuss the alleviation of H0 tension, that is obtained at the price of a phantom-like dark energy equation of state. We perform a Bayesian evidence analysis to quantify the improvement of the fit, finding that all the dark energy models considered in this work are preferred against the ΛCDM scenario. Finally, among all the possibilities analyzed, the CPL model is the best one in fitting the data and solving the H0 tension at the same time. However, unfortunately, this dynamical dark energy solution is not supported by the baryon acoustic oscillations (BAO) data, and the tension is restored when BAO data are included for all the models.

普朗克 CMB 最终释放和 H0 张力后的动态暗能量

在本文中，我们使用 2018 年普朗克遗留数据和 2015 年普朗克数据发布的宇宙微波背景测量、重子声学振荡测量和 SH0ES（超新星，H0 ，对于暗能量状态方程）合作分析哈勃太空望远镜数据。我们讨论了 H0 张力的缓解，这是以幻影般的暗能量状态方程为代价获得的。我们执行贝叶斯证据分析来量化拟合的改进，发现这项工作中考虑的所有暗能量模型都优于 ΛCDM 场景。最后，在分析的所有可能性中，CPL 模型是拟合数据和同时求解 H0 张力的最佳模型。
