Strong gravitational lensing around Kehagias-Sfetsos compact objects surrounded by plasma
Sudipta Hensh, Jan Schee, Ahmadjon Abdujabbarov +1
We present the analysis how Hořava gravity and plasma influence the strong lensing phenomena around Kehagias-Sfetsos (KS) black holes. Using the semi-analytical Bozza method of str…
Dynamics and Fundamental Frequencies of Test Particles Orbiting Kerr-Newman-NUT-Kiselev Blacks Hole in Rastall Gravity
Bakhtiyor Narzilloev, Ibrar Hussain, Ahmadjon Abdujabbarov +2
The spacetime properties in the exterior of the Kerr-Newman-NUT-Kiselev black hole in the Rastall theory of gravity, through particle dynamics are investigated with the aim to find…
Motion of charged and spinning particle influenced by dark matter field surrounding a charged dyonic black hole
Sanjar Shaymatov, Pankaj Sheoran, Sanjay Siwach
We investigate the motion of massive charged and spinning test particles around a charged dyonic black hole spacetime surrounded by perfect fluid scalar dark matter field. We obtai…
Motion of Particles and Gravitational Lensing Around (2+1)-dimensional BTZ black holes in Gauss-Bonnet Gravity
Bakhtiyor Narzilloev, Sanjar Shaymatov, Ibrar Hussain +3
We study motion of test particles and photons in the vicinity of (2+1) dimensional Gauss-Bonnet (GB) BTZ black hole. We find that the presence of the coupling constant serves as an…
Effects of gravitational lensing on neutrino oscillation in -spacetime
Hrishikesh Chakrabarty, Debasish Borah, Ahmadjon Abdujabbarov +2
We study the effects of gravitational lensing on neutrino oscillations in the -spacetime which describes a static, axially-symmetric and asymptotically flat solution of the Eins…
Dynamics of particles and epicyclic motions around Schwarzschild-de-Sitter black hole in perfect fluid dark matter
Javlon Rayimbaev, Sanjar Shaymatov, Mubasher Jamil
In this paper we investigate circular orbits for test particles around Schwarzschild-de Sitter (dS) black hole surrounded by perfect fluid dark matter. We determine the region of c…
Spinning test particle motion around a traversable wormhole
Carlos A. Benavides-Gallego, Wen-Biao Han, Daniele Malafarina +2
The motion of spinning test particles around a traversable wormhole is investigated using the Mathisson Papapetrous Dixon equations, which couple the Riemann tensor with the antisy…
Charged particle motion around a magnetized Reissner-Nordström black hole
Sanjar Shaymatov, Bakhtiyor Narzilloev, Ahmadjon Abdujabbarov +1
We investigate the dynamics of neutral and charged test particles around axially symmetric magnetized black hole spacetime. We consider its electromagnetic field in the black hole…
Testing the Kerr black hole hypothesis with the continuum-fitting and the iron line methods: the case of GRS 1915+105
Ashutosh Tripathi, Askar B. Abdikamalov, Dimitry Ayzenberg +4
The continuum-fitting and the iron line methods are currently the two leading techniques for probing the strong gravity region around accreting black holes. In the present work, we…
Particle motion around a static axially symmetric wormhole
Bakhtiyor Narzilloev, Daniele Malafarina, Ahmadjon Abdujabbarov +2
We consider the properties of a static axially symmetric wormhole described by an exact solution of Einstein's field equations and investigate how we can distinguish such a hypothe…
Charged black hole in Einstein-Gauss-Bonnet gravity: Particle motion, plasma effect on weak gravitational lensing and centre-of-mass energy
Farruh Atamurotov, Sanjar Shaymatov, Pankaj Sheoran +1
We study the motion of charged and spinning particles and photons in the charged Einstein-Gauss-Bonnet (EGB) black hole vicinity. We determine the radius of the innermost stab…
Dynamics of charged particles and magnetic dipoles around magnetized quasi-Schwarzschild black holes
Bakhtiyor Narzilloev, Javlon Rayimbaev, Ahmadjon Abdujabbarov +2
In the present paper, we have investigated the motion of charged particles together with magnetic dipoles to determine how well the spacetime deviation parameter and external u…
Can a light ray distinguish charge of a black hole in nonlinear electrodynamics?
Bobir Toshmatov, Bobomurat Ahmedov, Daniele Malafarina
It is a well-known fact that light rays do not follow the null geodesics of the space-time in nonlinear electrodynamics; instead, they follow the null geodesics of the so-called ef…
