Confining nonlinear electrodynamics black holes: from thermodynamic phases to high-frequency phenomena with accretion process

Erdem Sucu, Izzet Sakallı, Orhan Donmez +1

We investigate a static, spherically symmetric black hole solution arising from Einstein gravity coupled to a confining nonlinear electrodynamics model that reproduces Maxwell theo…

Structure and Mass-Radius Stability of Charged Compact Objects in Symmetric Teleparallel Euler-Heisenberg Gravity

Allah Ditta, M. Yousaf, G. Mustafa +4

In this work, we develop a new relativistic model for a charged anisotropic compact star in the framework of modified symmetric teleparallel gravity, namely -Euler-Heisenberg…

Magnetized particle motion and accretion process with shock cone morphology around a decoupled hairy black holes

G. Mustafa, Faisal Javed, S. K. Maurya +5

Relativistic accretion onto compact objects such as black holes and neutron stars is one of the most efficient known mechanisms for converting gravitational potential energy into r…

Analytical and numerical study of accretion processes around charged spherically symmetric black holes in scalar-tensor Gauss-Bonnet gravity

G. Mustafa, O. Donmez, A. Errehymy +5

We investigate the physical phenomena occurring around a spherically symmetric, non-rotating charged black hole (BH) to explore the effects of scalar-tensor Gauss-Bonnet gravity on…

Testing Quantum-Corrected Black Holes with QPOs Observations: A Study of Particle Dynamics and Accretion Flow

G. Mustafa, Sushant G. Ghosh, Orhan Donmez +3

We study the epicyclic oscillations of test particles around rotating quantum-corrected black holes (QCBHs), characterized by mass , spin , and quantum deformation parameter…

Study of Complexity Factor and Stability of Dynamical Systems in Gravity

M. Zeeshan Gul, W. Ahmad, M. M. M. Nasir +3

In this paper, we evaluate the complexity of the non-static cylindrical geometry with anisotropic matter configuration in the framework of modified Gauss-Bonnet theory. In this per…
