论文摘要
从本地距离梯子和宇宙微波背景测得的哈勃常数$ H_0 $的值之间的差异是对标准$λ$ CDM型号的最严重挑战。已经提出了各种模型来解决或缓解它，但是到目前为止尚未提供令人满意的解决方案。在这里，我们通过调查基于高斯进程（GP）方法的Hubble参数$ h（z）$数据，报告了$ h_ {0} $的延迟过渡，即$ h_0 $从低价值变为高值。这一发现有效地将哈勃危机减少了70 \％。我们的结果也与使用镜头镜头的时间覆盖量量的$σ$置信度水平的时间延迟宇宙学测量的$ H_0 $的下降趋势一致，并支持Hubble危机源于超越标准$λ$ CDM型号的新物理学的想法。此外，在$λ$ CDM型号和$ W $ CDM型号中，没有$ H_ {0} $的过渡行为。
The discrepancy between the value of the Hubble constant $H_0$ measured from the local distance ladder and from the cosmic microwave background is the most serious challenge to the standard $Λ$CDM model. Various models have been proposed to solve or relieve it, but no satisfactory solution has been given until now. Here, we report a late-time transition of $H_{0}$, i.e., $H_0$ changes from a low value to a high one from early to late cosmic time, by investigating the Hubble parameter $H(z)$ data based on the Gaussian process (GP) method. This finding effectively reduces the Hubble crisis by 70\%. Our results are also consistent with the descending trend of $H_0$ measured using time-delay cosmography of lensed quasars at 1$σ$ confidence level, and support the idea that the Hubble crisis arises from new physics beyond the standard $Λ$CDM model. In addition, in the $Λ$CDM model and $w$CDM model, there is no transition behavior of $H_{0}$.
