The disagreement between direct late-time measurements of the Hubble constant from the SH0ES collaboration, and early-universe measurements based on the ΛCDM model from the Planck collaboration might, at least in principle, be explained by new physics in the early universe. Recently, the application of the Effective Field Theory of Large-Scale Structure to the full shape of the power spectrum of the SDSS/BOSS data has revealed a new, rather powerful, way to measure the Hubble constant and the other cosmological parameters from Large-Scale Structure surveys. In light of this, we analyze two models for early universe physics, Early Dark Energy and Rock 'n' Roll, that were designed to significantly ameliorate the Hubble tension. Upon including the information from the full shape to the Planck, BAO, and Supernovae measurements, we find that the degeneracies in the cosmological parameters that were introduced by these models are well broken by the data, so that these two models do not significantly ameliorate thetension.

大尺度结构数据全形分析中的哈勃张力

SH0ES 合作对哈勃常数的直接后期测量与普朗克合作基于 ΛCDM 模型的早期宇宙测量之间的分歧至少在原则上可以用早期宇宙中的新物理学来解释。最近,将大尺度结构的有效场理论应用于 SDSS/BOSS 数据的完整功率谱,揭示了一种新的、相当强大的方法来测量哈勃常数和其他来自大尺度的宇宙学参数。规模结构调查。有鉴于此,我们分析了早期宇宙物理学的两个模型,早期暗能量和摇滚乐,它们旨在显着改善哈勃张力。在包括从完整形状到普朗克、BAO 和超新星测量的信息后,
