Mapping Quasi-Periodic Oscillations to Lyapunov Exponent across Black Hole Thermodynamic Phase Transitions
R. H. Ali, Xiao-Mei Kuang, Zi-Yu Tang
We investigate the thermodynamic phase structure of a nonminimally coupled magnetic AdS black hole through the dynamics of timelike particles. The free energy analysis reveals a Va…
Using precession and quasiperiodic oscillations to constrain a rotating regular black hole
Meng-He Wu, Hong Guo, Xiao-Mei Kuang
In this paper, we investigate the frame-dragging effect on an accretion disk and test gyroscope orbiting around a rotating regular black hole with a Minkowski core. Firstly, we per…
Parameter constraints on Horndeski rotating black hole through quasiperiodic oscillations
Meng-He Wu, Hong Guo, Xiao-Mei Kuang
In this paper, we perform small perturbations around the circular timelike orbit in the equatorial plane of the Horndeski rotating black hole, and analyze the effects of Horndeski…
Parameter constraints on a black hole with Minkowski core through quasiperiodic oscillations
Mingyu Guo, Menghe Wu, Xiaomei Kuang +1
We investigate the geodesic motion of charged particles in the vicinity of regular black holes with a Minkowski core, embedded in a uniform magnetic field, and study the influences…
Strong gravitational lensing effects around rotating regular black holes
Mingyu Guo, Menghe Wu, Hong Guo +2
In this letter, we investigate the strong gravitational lensing effects around two classes of rotating regular black holes, which behave as non-singular Minkowski core at the cente…
