Impact of $H_0$ priors on $f(T)$ late time cosmology

TL;DR

This paper investigates how different $H_0$ priors influence late-time cosmological parameters in five $f(T)$ gravity models, revealing significant impacts on $H_0$ and matter density estimates using various observational data sets.

Contribution

It provides a comprehensive analysis of the effects of recent $H_0$ priors on $f(T)$ cosmologies, highlighting their influence on key cosmological parameters.

Findings

Higher $H_0$ values with priors compared to no-prior analyses.

Lower matter density parameter when priors are applied.

Strong response of all parameters to different $H_0$ priors.

Abstract

We present a detailed analysis of the impact of $H_0$ priors from recent surveys in the literature on the late time cosmology of five $f(T)$ cosmological models using cosmic chronometers, the Pantheon data set, and baryonic acoustic oscillation data. In this work, we use three recently reported values of $H_0$ that have contributed to the recent $H_0$ tension problem. We find that these priors have a strong response in these analyses in terms of all the cosmological parameters. In general, our analyses gives much higher values of $H_0$ when considered against equivalent analyses without priors while, by and large, giving lower values of the matter density parameter. We close with a cross-analysis of each of our model, data set and prior combination choices.
