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 …

Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

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 …

Teleparallel gravity and its popular generalization gravity can be formulated as fully invariant
(under both coordinate transformations and local Lorentz transformations) theories of …

We investigate the scalar perturbations and the possible strong coupling issues of f (T)
around a cosmological background, applying the effective field theory (EFT) approach. We …

Cosmological perturbations are considered in f (T) and in scalar-torsion f (φ) T teleparallel
models of gravity. Full sets of linear perturbation equations are accurately derived and …

We investigate the cosmological predictions of several f (T) models, with up to two
parameters, at both the background and the perturbation levels. Using current cosmological …

The combined observation of GW170817 and its electromagnetic counterpart GRB170817A
reveals that gravitational waves propagate at the speed of light in high precision. We apply …
