f(T) gravity after DESI Baryon acoustic oscillation and DES supernovae 2024 data

Abstract

In this work, we investigate new constraints on f(T) gravity using the recent Baryon Acoustic Oscillation (BAO) data released by the Dark Energy Spectroscopic Instrument (DESI) and the Type Ia supernovae (SNIa) catalog from the full 5-years of the Dark Energy Survey Supernova Program (DES-SN5YR). The f(T) cosmological models considered are characterised by power law late-time accelerated expansion. Our results show that the combination DESI BAO +rd CMB Planck suggests a Bayesian preference for late-time f(T) cosmological models over ΛCDM, obtaining a value of H0=68.3−3.5+3.0 [km/s/Mpc] in agreement with SH0ES collaboration, however, due to a bigger uncertainty.
