We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

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 …

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 …

In the present paper, we investigate the thermodynamics of a new perturbed black hole
solution in symmetric teleparallel gravity. Our main focus is on the solution for a nonlinear …

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

The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

A bstract We present all scalar-tensor Lagrangians that are cubic in second derivatives of a
scalar field, and that are degenerate, hence avoiding Ostrogradsky instabilities. Thanks to …

We review different dark energy cosmologies. In particular, we present the Λ CDM
cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence …
