Description
In this study, we explore novel observational constraints within the framework of $f(T)$ gravity, focusing on the impact of primordial gravitational waves on the Cosmic Microwave Background (CMB) anisotropies and the B-mode polarization spectrum. Our investigation incorporates a teleparallel formulation for the background cosmology, enabling us to extend our analysis to include late-time cosmological datasets such as the Hubble data, Pantheon plus data, and Baryon Acoustic Oscillations (BAO) data from the DESI collaboration. By integrating these diverse datasets, we obtain a more comprehensive understanding of tensor perturbations within the $f(T) $ framework. Additionally, our study sheds light on the behaviour of cosmological tensions within this framework at late-time epochs. This approach enhances our grasp of $f(T) $ gravity's implications for the late-time universe, contributing to a deeper comprehension of its underlying dynamics.
