论文摘要
使用红移空间扭曲数据进行贝叶斯统计分析，以测试重力是非光的对称远程引力的模型。宇宙学背景模仿$λ$ CDM的演变，但在扰动中出现了差异。线性物质波动是数值演变的，并在这种宇宙学环境中分析了结构的生长速率。最佳拟合参数表明，在此框架内可以缓解普朗克和大规模结构数据之间的$σ_8$张力。
A Bayesian statistical analysis using redshift space distortions data is performed to test a model of Symmetric Teleparallel Gravity where gravity is non-metrical. The cosmological background mimics a $Λ$CDM evolution but differences arise in the perturbations. The linear matter fluctuations are numerically evolved and the study of the growth rate of structures is analysed in this cosmological setting. The best fit parameters reveal that the $σ_8$ tension between Planck and Large Scale Structure data can be alleviated within this framework.
