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 …

We review recent trends in inflationary dynamics in the context of viable modified gravity
theories. After providing a general overview of the inflationary paradigm emphasizing on …

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 review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the
subject of considerable interest over the past two years. Our review begins with a general …

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

Multimessenger gravitational-wave (GW) astronomy has commenced with the detection of
the binary neutron star merger GW170817 and its associated electromagnetic counterparts …

Primordial black holes formed in the early Universe via gravitational collapse of over-dense
regions may contribute a significant amount to the present dark matter relic density. Inflation …

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 …

We provide a theoretical model of F (R) gravity in which it is possible to describe in a unified
way inflation, an early and a late dark energy era, in the presence of a light axion particle …

We consider f (Q) extended symmetric teleparallel cosmologies, where Q is the non-metricity
scalar, and constrain its functional form through the order reduction method. By using this …
