Model-independent reconstruction of f (T) gravity from Gaussian Processes

YF Cai, M Khurshudyan… - The Astrophysical …, 2020 - iopscience.iop.org
We apply Gaussian processes and Hubble function data in f (T) cosmology to reconstruct for
the first time the f (T) form in a model-independent way. In particular, using H (z) data sets …

Structure formation in f (T) gravity and a solution for H0 tension

RC Nunes - Journal of Cosmology and Astroparticle Physics, 2018 - iopscience.iop.org

Covariant formulation of scalar-torsion gravity

M Hohmann, L Järv, U Ualikhanova - Physical Review D, 2018 - APS
We consider a generalized teleparallel theory of gravitation, where the action contains an
arbitrary function of the torsion scalar and a scalar field, f (T, ϕ), thus encompassing the …

Bayesian analysis of gravity using data

FK Anagnostopoulos, S Basilakos, EN Saridakis - Physical Review D, 2019 - APS
