论文摘要

最近,根据标准宇宙学模型,Planck-2018观察结果与宇宙微波背景镜头和星系聚类的合并观察到$ z \ sim4 $之间的新生长张力在$ 1 \,σ$置信水平上出现。我们证明,动态的暗能量可以很好地解决$ 1 \σ$置信度的张力。这意味着在高红移处的大规模结构的新测量可能会带来随着时间的推移进化的暗示。

Recently, under the standard cosmological model, a new growth tension between the Planck-2018 observation and the combined observation of cosmic microwave background lensing and galaxy clustering at $z\sim4$ emerges over the $1\,σ$ confidence level. We demonstrate that dynamical dark energy can well solve this tension within the $1\,σ$ confidence level. This implies that the new measurement of large scale structure at high redshift may give the evidence of evolution of dark energy over time.
