Cyclic and heteroclinic flows near general static spherically symmetric black holes: semi-cyclic flows - addendum and corrigendum
Azreg-Ainou, Mustapha (2017)We present new accretion solutions of a polytropic perfect fluid onto an f(R)-gravity de Sitter-like black hole. We consider two f(R)-gravity models and obtain finite-period cyclic flows oscillating between the event and ... -
Epicyclic oscillations of charged particles in stationary solutions immersed in a magnetic field with application to the Kerr-Newman black hole
Azreg-Ainou, Mustapha (2019)We consider a stationary metric immersed in a uniform magnetic field and determine the general expressions for the epicyclic frequencies of charged particles. Applications to the Kerr-Newman black hole are reached of ... -
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 ... -
Gyroscope precession frequency analysis of a five-dimensional charged rotating Kaluza-Klein black hole
Azreg-Ainou, Mustapha; Jamil, Mubasher; Lin, Kai (2020)We study the spin precession frequency of a test gyroscope attached to a stationary observer in the five-dimensional rotating Kaluza-Klein black hole (RKKBH). We derive the conditions under which the test gyroscope moves ... -
High-pressure effects on the benzene pre-crystallization metastable states
Azreg-Ainou, Mustapha; Ibrahimoglu, Beycan (2019)We report new results on the liquid to solid phase transition of benzene. We determine experimentally and investigate the properties of a number of parameters of the benzene metastable state under different pressures (from ... -
On 'rotating charged AdS solutions in quadratic f(T) gravity': new rotating solutions
Azreg-Ainou, Mustapha (2020)We show that there are two or more procedures to generalize the known four-dimensional transformation, aiming to generate cylindrically rotating charged exact solutions, to higher dimensional spacetimes. In the one procedure, ... -
Rotating normal and phantom Einstein-Maxwell-dilaton black holes: Geodesic analysis
Azreg-Ninou, Mustapha; Haroon, Sumarna; Jamil, Mubasher; Rizwan, Muhammed (2019)Depending on five parameters, rotating counterparts of Einstein-Maxwell-dilaton black holes are derived. We discuss their physical and geometric properties and investigate their null and timelike geodesics including circular ... -
Smoothed one-core and core-multi-shell regular black holes
Azreg-Ainou, Mustapha (2018)We discuss the generic properties of a general, smoothly varying, spherically symmetric mass distribution D(r,theta), with no cosmological term (. is a length scale parameter). Observing these constraints, we show that ... -
Strong gravitational lensing by a charged Kiselev black hole
Azreg, Ainou Mustapha; Bahamonde, Sebastian; Jamil, Mubasher (2017)We study the gravitational lensing scenario where the lens is a spherically symmetric charged black hole (BH) surrounded by quintessence matter. The null geodesic equations in the curved background of the black hole are ...
