Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

This paper investigates the concept of cracking and overturning to analyze the impact of
local density perturbations on the stability of self-gravitating compact objects in the …

This paper investigates the behavior of charged compact stars in the modified f (R, ϕ) theory
of gravity, where R and ϕ denote the Ricci scalar and scalar field respectively. The modified …

This work aims to investigate the wormhole solutions in the background of f (R, φ, X) theory
of gravity, where R is Ricci scalar, φ is scalar potential, and X is the kinetic term. We consider …

In this article, we aim to investigate some cylindrically symmetric solutions in a very well
known modified theory named as\(f (R,\phi, X)\) theory of gravity, where the terms R,\(\phi\) …

Abstract f (Q) symmetric-teleparallel gravity is considered in view of quantum cosmology.
Specifically, we derive cosmological equations for f (Q) models and then investigate the …

In this manuscript, we investigate the behavior of stellar structure through embedding
approach in\(f (R,\phi, X)\) modified theory of gravity, where R denotes the Ricci scalar,\(\phi\) …

This manuscript examines how effective matter variables influence the geometry of compact
stellar objects with anisotropic matter configuration in modified f (R, φ, χ) gravity, where R …

A bstract We study the degrees of freedom of R 2 gravity in flat spacetime with two
approaches. By rewriting the theory a la Stueckelberg, and implementing Lorentz-like …

The primary objective of this paper is to examine singularity-free solutions within the
framework of anisotropic solutions for the Chaplygin equation of state in f (R, ϕ, X) modified …
