Axion-plasmon or magnetized plasma effect on an observable shadow and gravitational lensing of a Schwarzschild black hole
Atamurotov, Farruh; Jusufi, Kimet; Jamil, Mubasher; Abdujabbarov, Ahmadjon; Azreg-Ainou, Mustapha (2021)In this paper, we study the influence of the axion-plasmon, as proposed in [Phys. Rev. Lett. 120, 181803 (2018)] on the optical properties of the Schwarzschild black hole. Our aim is to provide a test to detect the effects ... -
Constraining the generalized uncertainty principle through black hole shadow, S2 star orbit, and quasiperiodic oscillations
Jusufi, Kimet; Azreg-Ainou, Mustapha; Jamil, Mubasher; Zhu, Tao (2022)In this paper, we study the effect of the Generalized Uncertainty Principle (GUP) on the shadow of GUP-modified Kerr black hole and the correspondence between the shadow radius and the real part of the quasinormal modes ... -
Constraining Wormhole Geometries Using The Orbit Of S2 Star And The Event Horizon Telescope
Jusufi, Kimet; Kumar, Saurabh; Azreg-Ainou, Mustapha; Jamil, Mubasher; Wu, Qiang; Bambi, Cosimo (2022)In this paper we study the possibility of having a wormhole (WH) as a candidate for the Sgr A(star) central object and test this idea by constraining their geometry using the motion of S2 star and the reconstructed shadow ... -
Constraints on Barrow Entropy from M87* and S2 Star Observations
Jusufi, Kimet; Azreg-Ainou, Mustapha; Jamil, Mubasher; Saridakis, Emmanuel N. (2022)We use data from M87* central black hole shadow, as well as from the S2 star observations, in order to extract constraints on Barrow entropy. The latter is a modified entropy arising from quantum-gravitational effects on ... -
Equatorial and Polar Quasinormal Modes and Quasiperiodic Oscillations of Quantum Deformed Kerr Black Hole
Jusufi, Kimet; Azreg Ainou, Mustapha; Jamil, Mubasher; Wu, Qiang (2022)In this paper, we focus on the relation between quasinormal modes (QNMs) and a rotating black hole shadow. As a specific example, we consider the quantum deformed Kerr black hole obtained via Newman-Janis-Azreg-Ainou ... -
Quasinormal modes, quasiperiodic oscillations, and the shadow of rotating regular black holes in nonminimally coupled Einstein-Yang-Mills theory
Jusufi, Kimet; Azreg-Ainou, Mustapha; Jamil, Mubasher; Wei, Shao-Wen; Wu, Qiang; Wang, Anzhong (2021)In this paper, we obtain an effective metric describing a regular and rotating magnetic black hole (BH) solution with a Yang-Mills electromagnetic source in Einstein-Yang-Mills (EYM) theory using the Newman-Janis (NJ) ... -
Shadow and quasinormal modes of a rotating loop quantum black hole
Liu, Cheng; Zhu, Tao; Wu, Qiang; Jusufi, Kimet; Jamil, Mubasher; Azreg-Ainou, Mustapha; Wang, Anzhong (2020)In this paper, we construct an effective rotating loop quantum black hole (LQBH) solution, starting from the spherical symmetric LQBH by applying the Newman-Janis algorithm modified by Azreg-Ainou's noncomplexification ... -
Shadow, quasinormal modes, and quasiperiodic oscillations of rotating Kaluza-Klein black holes
Ghasemi-Nodehi, M.; Azreg-Ainou, Mustapha; Jusufi, Kimet; Jamil, Mubasher (2020)In this paper we study the shadow of rotating Kaluza-Klein (KK) black holes and the connection between the shadow radius and the real part of quasinormal modes (QNMs) in the eiokonal limit. In addition we have explored the ...
