$f(T,B)$ Gravity in the late Universe in the context of local measurements

TL;DR

This paper evaluates three $f(T,B)$ gravity models against late universe observational data, including cosmic chronometers, Pantheon supernovae, and BAO, considering different Hubble constant priors to test their viability and consistency.

Contribution

It introduces a comprehensive analysis of $f(T,B)$ gravity models using multiple datasets and priors, assessing their fit and consistency with late universe observations.

Findings

Models fit late-time data more consistently than previous models.

Each model requires an additional parameter compared to the standard cosmological model.

The analysis highlights the impact of different Hubble constant priors on model viability.

Abstract

We explore the viability of three models in $f(T,B)$ gravity using data from recent surveys based on cosmic chronometers, the Pantheon data set, and baryonic acoustic oscillation data. We also assess the consistency of these models and data set combinations with two important priors on the Hubble constant coming from the SH0ES Team and measurements using the tip of the red giant branch respectively. These give the highest and lowest values of the Hubble constant coming from cosmology independent studies. In general, our analysis does provide a more consistent fit for the late time data being analyzed. However, each model does include an additional model parameter in comparison with the concordance model. We close the analysis with a comparative analysis in which each model, data set and Hubble constant prior combination are cross-analyzed against each other.
