Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

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 …

We consider gravity mediated by non-metricity, with vanishing curvature and torsion. The
gravitational action, including an arbitrary function of the non-metric scalar, is investigated in …

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

We explore whether nonstandard dark sector physics might be required to solve the existing
cosmological tensions. The properties we consider in combination are (a) an interaction …

Cosmography can be considered as a sort of a model-independent approach to tackle the
dark energy/modified gravity problem. In this review, the success and the shortcomings of …

We propose a new entropy construct that generalizes the Tsallis, Rényi, Sharma-Mittal,
Barrow, Kaniadakis, and loop quantum gravity entropies and reduces to the Bekenstein …

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 …
