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…
Grey-Body Factors and Thermodynamics of Asymptotically de Sitter Black Holes in Generalized Proca Theory
Bekir Can Lütfüoğlu, Javlon Rayimbaev, Nuriddin Kurbonov +2
Generalized Proca theory supplements gravity with a massive vector field whose derivative self-interactions can support black holes carrying primary vector hair. In the asymptotica…
Bardeen spacetime as quantum corrected black hole: Grey-body factors and quasinormal modes of gravitational perturbations
Bekir Can Lütfüoğlu, Javlon Rayimbaev, Sardor Murodov +2
We study axial gravitational perturbations of the asymptotically flat Bardeen spacetime interpreted as a string-T-duality-inspired quantum-corrected Schwarzschild black hole. Start…
A First-Order Eikonal Framework for Quasinormal Modes, Shadows, Strong Lensing, and Grey-Body Factors in a Scalarized Black-Hole Metric
Bekir Can Lütfüoğlu, Javlon Rayimbaev, Sardor Murodov +2
We construct an analytic geodesic-optics description of quasinormal ringing, black-hole shadows, strong lensing, and grey-body factors for the static spherical metric introduced in…
Holographic dark energy as a source for slowly rotating wormholes: Implications for null geodesics and shadows
A. Errehymy, S. K. Maurya, M. Govender +4
In this work, we explore for the first time slowly rotating traversable wormholes embedded in holographic dark energy. We focus on three representative holographic dark energy mode…
Probing geometrically perturbed strange stars with minimal decoupling using millisecond pulsar timing observations
K. N. Singh, S. K. Maurya, A. Errehymy +3
We construct a gravitationally decoupled anisotropic strange star model using the minimal geometric deformation approach with a MIT bag equation of state and an additional source s…
Observational constraints on viscous cosmology in gravity
M. Koussour, Alnadhief H. A. Alfedeel, S. Muminov +1
We investigate the late-time cosmic acceleration within the framework of viscous gravity, where the gravitational action depends on both the torsion scalar and the m…
Ringing Regularity: Gravitational Perturbations and Quasinormal Modes of Einasto-Supported Black Holes
Bekir Can Lütfüoğlu, Javlon Rayimbaev, Sardor Murodov +2
We investigate axial gravitational perturbations and quasinormal modes of regular black holes supported by an Einasto distribution of matter. Halo matter not only removes the centr…
Two types of quasinormal modes of Casadio-Fabbri-Mazzacurati brane-world black holes
Bekir Can Lütfüoğlu, Sardor Murodov, Mardon Abdullaev +3
Using the convergent Leaver method, we investigate the quasinormal modes of a massive scalar field propagating in the background of the Casadio--Fabbri--Mazzacurati (CFM) brane-wor…
Probing the nature of Einstein nonlinear Maxwell Yukawa black hole through gravitational wave forms from periodic orbits and quasiperiodic oscillations
Oreeda Shabbir, Abubakir Shermatov, Bushra Majeed +3
In this work, we study gravitational wave emission from periodic orbits of test particles, analyze quasi periodic oscillations, and constrain the parameters of the static, spherica…
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…
