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

One century after its formulation, Einstein's general relativity (GR) has made remarkable
predictions and turned out to be compatible with all experimental tests. Most of these tests …

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 …

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 …

We derive a new interior solution for stellar compact objects in\(f\mathcal {(R)}\) gravity
assuming a differential relation to constrain the Ricci curvature scalar. To this aim, we …

This article is devoted to the study of high dense charged anisotropic compact structures in
the framework of f (R, T) gravity theory. The principal aims of this investigation, regard the …

In the context of $ f (R)= R+\alpha R^{2} $ gravity, we study the existence of neutron and
quark stars for various α with no intermediate approximation in the system of equations …

Rotating relativistic stars have been studied extensively in recent years, both theoretically
and observationally, because of the information they might yield about the equation of state …

The aim of this manuscript is to investigate the charged anisotropic compact stars in f (R, A)
theory of gravity, namely Ricci-Inverse gravity. By employing the Karmarkar condition, we …

Recent observation shows that general relativity (GR) is not valid in the strong regime. f (R)
gravity, where R is the Ricci scalar, is regarded to be a good candidate able to cure the …
