Relativistic accretion process onto rotating black holes in Einstein-Euler-Heisenberg nonlinear electrodynamic gravity
Orhan Donmez, G. Mustafa, Himanshu Chaudhary +4
In this study, we uncover the accretion dynamics and oscillatory behavior around rotating black holes within the EEH nonlinear electrodynamic framework by analyzing both the motion…
Origin of Quasi-Periodic Oscillations and Accretion Process in X-Ray Binaries around Quantum Lee-Wick Black Hole
Orhan Donmez, G. Mustafa, M. Yousaf +3
In this study, we investigate the accretion dynamics and test particle motion around a non-rotating, spherically symmetric Lee-Wick black hole (BH) to reveal how the model paramete…
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…
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…
ACT Constraints on Marginally Deformed Starobinsky Inflation
Jureeporn Yuennan, Farruh Atamurotov, Phongpichit Channuie
We investigate the inflationary phenomenology of a marginally deformed Starobinsky model, motivated by quantum corrections to the term, in light of the latest cosmological…
Thermodynamics of Einstein-Geometric Proca AdS compact objects
Asalkhon Alimova, Elham Ghorani, Beyhan Puliçe +2
In this study we explore metric-Palatini gravity extended by the antisymmetric component of the affine curvature. This gravitational theory results in general relativity plus a geo…
Influence of external magnetic fields on charged particle motion around a Schwarzschild-like black hole
Sojida Mannobova, Gulnisa Abdukayumova, Farruh Atamurotov +3
We investigate the dynamics of charged and neutral particles in the vicinity of a Schwarzschild-like black hole immersed in an external magnetic field. We find that the innermost s…
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…
Probing single-field inflation: predictions, constraints, and theoretical viewpoints
Fereshteh Felegary, Thammarong Eadkhong, Farruh Atamurotov +1
This work investigates a single-field inflationary model, a specific class of the K-essence models where a coupling term exists between canonical Lagrangian and the potential. This…
Dark Sector Interactions: Probing the Hubble Parameter and the Sound Horizon
Ritika Nagpal, S. K. J. Pacif, Farruh Atamurotov +1
In this study, we explore the impact of the interacting parameter on dark matter in a model resulting from a parametrization of dark energy density. To ensure a model-independent a…
Observable Signatures of RN Black Holes with Dark Matter Halos via Strong Gravitational Lensing and Constraints from EHT Observations
Niyaz Uddin Molla, Himanshu Chaudhary, Salvatore Capozziello +3
We investigate the impact of dark matter halos on the gravitational lensing produced by electrically charged, spherically symmetric black holes in the strong-field regime. The stud…
Influence of Quantum Correction on Kerr Black Hole in Effective Loop Quantum Gravity via Shadows and EHT Results
Muhammad Ali Raza, M. Zubair, Farruh Atamurotov +1
Recently, a study on shadow of quantum corrected Schwarzschild black hole in loop quantum gravity appeared in [Ye et al., Phys. Lett. B 851, 138566, (2024)] assuming a fixed value…
