Dynamics of test particles around a Bardeen black hole surrounded by perfect fluid dark matter
Bakhtiyor Narzilloev, Javlon Rayimbaev, Sanjar Shaymatov +3
We study the dynamics of (i) neutral test particles, (ii) magnetically charged test particles, and (iii) test magnetic dipole around a regular Bardeen black hole surrounded by perf…
Dynamics of test particles around renormalization group improved Schwarzschild black holes
Javlon Rayimbaev, Ahmadjon Abdujabbarov, Mubasher Jamil +2
In this paper we have investigated the dynamics of neutral, electrically charged and magnetized particles around renormalized group improved (RGI) Schwarzschild black hole in the p…
Test particle motion around black hole in Einstein-Maxwell-scalar theory
Bobur Turimov, Javlon Rayimbayev, Ahmadjon Abdujabbarov +2
In this paper, we explore the test particle motion around a black hole in Einstein-Maxwell-scalar (EMS) theory using three different black hole solutions within this theory. We hav…
Dynamics of magnetized particles around Einstein-Æther black hole with uniform magnetic field
Javlon Rayimbaev, Ahmadjon Abdujabbarov, Mubasher Jamil +1
This work is devoted to study the effects of Einstein-Æther gravity on the dynamics of magnetized particles orbiting a static, spherically symmetric and uncharged black hole immers…
Can the dynamics of test particles around charged stringy black holes mimic the spin of Kerr black holes?
Bakhtiyor Narzilloev, Javlon Rayimbaev, Sanjar Shaymatov +3
We study the motion of electrically charged particles, magnetic monopoles, and magnetic dipoles around electrically and magnetically charged stringy black holes. From the analysis…
Charged particle and epicyclic motions around Einstein-Gauss-Bonnet black hole immersed in an external magnetic field
Sanjar Shaymatov, Jaroslav Vrba, Daniele Malafarina +2
We investigate particle motion in the vicinity of a Einstein-Gauss-Bonnet (EGB) black hole immersed in external asymptotically uniform magnetic field. It is well known that ma…
Quasi-harmonic oscillations of charged particles in static axially symmetric space-times immersed in a uniform magnetic field
Carlos A. Benavides-Gallego, Ahmadjon Abdujabbarov, Daniele Malafarina +1
In continuation of our previous study [Phys. Rev. D 99 (2019) 4, 044012], we investigate the motion of charged particles in the -metric. We provide some examples of curled traje…
Testing the weak cosmic censorship conjecture for a Reissner-Nordström-de Sitter black hole surrounded by perfect fluid dark matter
Sanjar Shaymatov, Bobomurat Ahmedov, Mubasher Jamil
In this paper, we test the weak cosmic censorship conjecture (WCCC) for the Reissner-Nordström-de Sitter (RN-dS) black hole surrounded by perfect fluid dark matter. We consider a s…
Dust collapse in 4D Einstein-Gauss-Bonnet gravity
Daniele Malafarina, Bobir Toshmatov, Naresh Dadhich
We consider gravitational collapse in the recently proposed 4D limit of Einstein-Gauss-Bonnet gravity. We show that for collapse of a sphere made of homogeneous dust the process is…
Charged particle motion around non-singular black holes in conformal gravity in the presence of external magnetic field
Bakhtiyor Narzilloev, Javlon Rayimbaev, Ahmadjon Abdujabbarov +1
We consider electromagnetic fields and charged particle dynamics around non-singular black holes in conformal gravity immersed in an external, asymptotically uniform magnetic field…
Magnetized particle motion around magnetized Schwarzschild-MOG black hole
Kamoliddin Haydarov, Javlon Rayimbaev, Ahmadjon Abdujabbarov +2
In this paper, we have presented the studies of the motion of magnetized particles and energetic processes around Schwarzschild black holes in modified gravity (MOG). The study of…
On overspinning of black holes in higher dimensions
Sanjar Shaymatov, Naresh Dadhich
It turns out that repulsive effect due to rotation of a rotating black hole dominates over attraction due to mass for large in dimensions . This gives rise to a remarkable…
On the properties of a deformed extension of the NUT space-time
Bakhtiyor Narzilloev, Daniele Malafarina, Ahmadjon Abdujabbarov +1
We consider a class of space-times given by a stationary extension of the Zipoy-Voorhees metric that was found by Halilsoy. We show that the solutions do not describe rotating sour…
Motion of spinning particles in non asymptotically flat spacetimes
Bobir Toshmatov, Ozodbek Rahimov, Bobomurat Ahmedov +1
The assumption of asymptotic flatness for isolated astrophysical bodies may be considered an approximation when one considers a cosmological context where a cosmological constant o…
