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 …

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 …

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 revisit the possibility that the stochastic common-spectrum process recently detected by
the NANOGrav pulsar timing array experiment could be due to primordial gravitational …

Early observations with the James Webb Space Telescope (JWST) have revealed the
existence of an unexpectedly large abundance of extremely massive galaxies at redshifts z≳ …

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 …

In this work we introduce a new theoretical framework for Einstein-Gauss-Bonnet theories of
gravity, which results to particularly elegant, functionally simple and transparent gravitational …

We provide a refined and much more simplified Einstein–Gauss–Bonnet inflationary
theoretical framework, which is compatible with the GW170817 observational constraints on …

Recently, there has been a surge of interest in the 4D Einstein-Gauss-Bonnet (4D EGB)
gravity theory which bypasses the Lovelock theorem and avoids Ostrogradsky's instability …
