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 …

f(Q, T) gravity
We propose an extension of the symmetric teleparallel gravity, in which the gravitational
action L is given by an arbitrary function f of the non-metricity Q and of the trace of the matter …

Coupling matter in modified gravity
We present a novel theory of gravity by considering an extension of symmetric teleparallel
gravity. This is done by introducing, in the framework of the metric-affine formalism, a new …

Relaxing cosmological tensions with a sign switching cosmological constant
Inspired by the recent conjecture originated from graduated dark energy that the Universe
has recently transitioned from anti–de Sitter vacua to de Sitter vacua, we extend the …

Modeling wormholes in gravity
In this work, we propose the modeling of static wormholes within the f (R, T) extended theory
of gravity perspective. We present some models of wormholes, which are constructed from …

Dark energy stars and quark stars within the context of f (Q) gravity
In this work, we investigate the relativistic structure of compact stars within the framework of f
