Dynamical and static solutions to R=0 scalar-tensor theory
(2020)
We consider the most cosmologically interesting and relevant case of scalar-tensor theory (STT) and derive new normal and phantom, dynamical and static, solutions. We determine the Bianchi I Kasner exponents and show that ...
Orbital mechanics and quasiperiodic oscillation resonances of black holes in Einstein-AEther theory
(2020)
In this paper, we study the motion of test particles around two exact charged black hole solutions in Einstein-AEther theory. Specifically, we first consider the quasiperiodic oscillations (QPOs) and their resonances ...
Shadow, quasinormal modes, and quasiperiodic oscillations of rotating Kaluza-Klein black holes
(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 ...
Shadow and quasinormal modes of a rotating loop quantum black hole
(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 ...
Cylindrically symmetric static n-dimensional (un)charged (anti-)de Sitter black holes in generic f(T) gravity
(2020)
Given a generic function f(T) we construct in closed forms cylindrically symmetric static n-dimensional uncharged and charged de Sitter and anti-de Sitter solutions (including black holes, wormholes and possibly other ...
Gyroscope precession frequency analysis of a five-dimensional charged rotating Kaluza-Klein black hole
(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 ...
