Teleparallel gravity: from theory to cosmology
Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

f (T) teleparallel gravity and cosmology
Over recent decades, the role of torsion in gravity has been extensively investigated along
the main direction of bringing gravity closer to its gauge formulation and incorporating spin …

Structure formation in f (T) gravity and a solution for H0 tension
RC Nunes - Journal of Cosmology and Astroparticle Physics, 2018 - iopscience.iop.org
We investigate the evolution of scalar perturbations in f (T) teleparallel gravity and its effects
on the cosmic microwave background (CMB) anisotropy. The f (T) gravity generalizes the …

Can Horndeski theory be recast using teleparallel gravity?
Horndeski gravity is the most general scalar tensor theory, with a single scalar field, leading
to second-order field equations and after the GW170817 it has been severely constrained …

New observational constraints on f (T) gravity from cosmic chronometers
We use the local value of the Hubble constant recently measured with 2.4% precision, as
well as the latest compilation of cosmic chronometers data, together with standard probes …

The gravitation energy–momentum pseudotensor: The cases of and gravity
We derive the gravitational energy–momentum pseudotensor τ λ σ in metric f (R) gravity and
in teleparallel f (T) gravity. In the first case, R is the Ricci curvature scalar for a torsionless …

Phase Portraits of general f (T) Cosmology
We use dynamical system methods to explore the general behaviour of f (T) cosmology. In
contrast to the standard applications of dynamical analysis, we present a way to transform …

Effective gravitational coupling in modified teleparallel theories
In the present study, we consider an extended form of teleparallel Lagrangian f (T, ϕ, X), as
function of a scalar field ϕ, its kinetic term X and the torsion scalar T. We use linear …
