Abstract

In this paper, we present independent determinations of cosmological parameters and new constraints on f(T) cosmologies, employing two new catalogs related to HII galaxy Hubble and CMB distance priors, along with the local standard measurements, SNIa, H(z) measurements, growth rate data (RSD), and BAO baselines. We found that the marginalized best-fit C.L. H0 and σ8 parameters within f(T) cosmologies allow f(T) to relax the current cosmological tensions using HIIG data, which produces a larger range of admissible values for the current Hubble constant, and when all baselines are considered, the uncertainty bands for H0 and the matter density parameter reduce significantly.

用 HII 哈勃图和 CMB 距离先验检验 f(T) 宇宙学
在本文中,我们利用与HII星系哈勃和CMB距离先验相关的两个新星表,以及本地标准测量、SNIa、H(z)测量、增长率数据(RSD)和BAO基线,提出了对f(T)宇宙学参数的独立测定和新约束。我们发现,f(T)宇宙学中的边际化最佳拟合C.L. H0和σ8参数允许f(T)利用HIIG数据放宽当前的宇宙学张力,这就为当前的哈勃常数产生了更大的可容许值范围,而且当考虑到所有基线时,H0和物质密度参数的不确定性带也会显著减小。
