The f(T,𝒯) gravity model, a modification of general relativity, can potentially address the Hubble constant (H0) tension and explain the late-time accelerated expansion of the universe, with the choice of H0 priors significantly influencing the model's results and its comparison to the standard ΛCDM model.
This research paper presents constraints on deviations from General Relativity using the first year of clustering measurements from the Dark Energy Spectroscopic Instrument (DESI) combined with other cosmological probes, finding the results consistent with General Relativity.
