摘要

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。

Testing f(T) cosmologies with HII Hubble diagram and CMB distance priors

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. $H_{0}$ and $σ_{8}$ 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 $H_{0}$ and the matter density parameter reduce significantly.
