Probing black holes surrounded by Dust field in Quantum Fluctuation Modified Gravity with twin-peak QPOs
Kamola Shermatova, Qodir Badalov, Abubakir Shermatov +5
We study a static, spherically symmetric black hole solution surrounded by a dust field within quantum fluctuation modified gravity, in which the quantum-fluctuation parameter …
Kerr-referenced analytical parametrization of rotating black holes in dynamical Chern-Simons gravity
Sardor Murodov, Bahodir Ahmedov, Bekzod Rahmatov +2
Rotating black holes in dynamical Chern-Simons gravity are known nonperturbatively mainly through numerical solutions, which limits their direct use in strong-field applications. W…
Weakly nonlinear strong-field signatures of spontaneously vectorized Einstein-vector-Gauss-Bonnet black holes near the Schwarzschild bifurcation
Sardor Murodov, Bekzod Rahmatov, Islom Egamberdiev +3
We study the static, spherically symmetric electric branch of spontaneously vectorized Einstein-vector-Gauss-Bonnet black holes close to its Schwarzschild bifurcation. A weakly non…
Blandford-Znajek Scaling in a Power-Law Rotating Kalb-Ramond Geometry: Magnetic-Flux Systematics and Bayesian Identifiability
Sardor Murodov, Olimjon Kholturayev, Bekzod Rahmatov +3
Relativistic jets from spinning black holes offer a possible strong-field probe of gravity through the Blandford-Znajek mechanism. We study the leading jet-power scaling in the fou…
Massive neutral Dirac quasibound states in a Newman-Janis-generated rotating charged Kalb-Ramond black-hole geometry
Sardor Murodov, Olimjon Kholturayev, Bahodir Ahmedov +3
We study quasibound states of a massive neutral Dirac field in the Newman-Janis-generated rotating charged geometry used in Lorentz-violating Kalb-Ramond (KR) gravity. Rather than…
Circular-orbit dynamics and QPO constraints in static Einstein--scalar--Gauss--Bonnet black holes
Sardor Murodov, Bekzod Rahmatov, Otabek Umarov +3
Einstein--scalar--Gauss--Bonnet (EsGB) gravity provides a physically motivated framework for testing strong-field deviations from the Schwarzschild geometry through scalar hair. We…
Particle dynamics and quasi-periodic oscillations of a Reissner--Nordström-like black hole in Kalb--Ramond gravity under an external magnetic test field
Faizuddin Ahmed, Ahmad Al-Badawi, Sardor Murodov +2
We investigate the dynamics of charged test particles and quasi-periodic oscillations around a Reissner--Nordström-like black hole in Kalb--Ramond (KR) gravity in the presence of a…
Greybody Factors, Absorption Cross Sections and Hawking Radiation of Holonomy-Corrected Schwarzschild Black Holes
Bekir Can Lütfüoğlu, Javlon Rayimbaev, Bekzod Rahmatov +2
We study greybody factors, absorption cross sections and Hawking energy-emission rates for minimally coupled massless scalar, electromagnetic and massless Dirac test fields on the…
Black holes in general relativity coupled with NEDs surrounded by PFDM: thermodynamics, epicyclic oscillations, QPOs, and shadow
Faizuddin Ahmed, Sardor Murodov, Bekzod Rahmatov
In this work, we investigate the thermodynamics and motion of neutral test particles around a regular black hole immersed in a perfect fluid dark matter environment. We begin by ex…
Dymnikova Black Hole Immersed in Perfect Fluid Dark Matter and a Cloud of Strings: Hawking Temperature, Dynamics and QPOs Analysis
Faizuddin Ahmed, Sardor Murodov, Bekzod Rahmatov +1
The Dymnikova black hole represents a regular spacetime solution interpolating between a de Sitter core and an asymptotically Schwarzschild geometry. In this work, we investigate a…
Telling tails and quasi-resonances in the vicinity of Dymnikova regular black hole
Bekir Can Lütfüoğlu, Javlon Rayimbaev, Bekzod Rahmatov +2
We investigate quasinormal modes, late-time tails, and grey-body factors for massive scalar perturbations in the background of the Dymnikova regular black hole. By applying both th…
