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…
Constraining non-minimally coupled squared-Quartic Hilltop Inflation in light of ACT observations
Jureeporn Yuennan, Farruh Atamurotov, Phongpichit Channuie
The combination of the data from the Dark Energy Spectroscopic Instrument (DESI) with the recent measurements from the Atacama Cosmology Telescope (ACT) indicate that the scalar sp…
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…
