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

TL;DR

This paper uses HII galaxy data, CMB priors, and other cosmological measurements to constrain $f(T)$ gravity models, finding they can alleviate current tensions in $H_0$ and $\sigma_8$ estimates.

Contribution

It introduces new constraints on $f(T)$ cosmologies using HII galaxy and CMB data, demonstrating their potential to relax existing cosmological tensions.

Findings

HII galaxy data relaxes $H_0$ and $\sigma_8$ tensions.

Combined data reduces uncertainties in cosmological parameters.

$f(T)$ models can accommodate a wider range of $H_0$ values.

Abstract

In this work, 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 marginalised best-fit C.L. $H_0$ and $\sigma_8$ parameters within these cosmologies can relax the current cosmological tensions using HIIG data. This 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.
