A model-independent compact dynamical system formulation for exploring bounce and cyclic cosmological evolutions in gravity

A. S. Agrawal, Charlotte Louw, Saikat Chakraborty +1

Using the dynamical systems approach together with the cosmographic parameters, we present a model-independent dynamical system formulation for cosmology in f(R) gravity. The formu…

Kerr black hole in presence of force-free magnetic field

Haidar Sheikhahmadi

We extend the study of force-free magnetospheres from non-rotating to rotating black holes \cite{Sheikhahmadi} and investigate the influence of a force-free magnetic field on the g…

Cosmological implications of the constant jerk parameter in gravity theory

N. Myrzakulov, M. Koussour, Alnadhief H. A. Alfedeel +1

This study delves into modified gravity theories that are equivalent to General Relativity but involve the torsion or non-metricity scalar instead of the curvature scalar. Specific…

Modeling cosmic acceleration with a generalized varying deceleration parameter

M. Koussour, N. Myrzakulov, Alnadhief H. A. Alfedeel +2

Understanding the accelerating expansion of the Universe remains a fundamental challenge in modern cosmology. In this paper, we investigate a cosmological model parametrized by a g…

Impact of dark energy on the equation of state in light of the latest cosmological data

N. Myrzakulov, M. Koussour, Alnadhief H. A. Alfedeel +1

We reconstruct the effective Equation of State (EoS) within the framework of General Relativity (GR) theory in a homogeneous and isotropic FLRW Universe, which is assumed to be com…

Black hole solutions to Einstein-Bel-Robinson gravity

S. N. Sajadi, Robert B. Mann, H. Sheikhahmadi +1

In this paper, we study the physical properties of black holes in the framework of the recently proposed Einstien-Bel-Robinson gravity. We show that interestingly the theory propag…
