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

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 …

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 …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

The objective of this paper is to unveil the evolving traversable wormhole solutions within
the perspective of modified f (R, G) gravity, where R is Ricci scalar and G is Gauss Bonnet …

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

Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of
General Relativity at infrared and ultraviolet scales. They are an approach that, by …

In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

The classical generalization of general relativity is considered as the gravitational alternative
for a unified description of the early-time inflation with late-time cosmic acceleration. The …
