Greybody Factors, Absorption Cross Sections and Hawking Radiation of Holonomy-Corrected Schwarzschild Black Holes
Bekir Can LütfüoÄlu, 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 LütfüoÄlu, 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 LütfüoÄlu, 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 LütfüoÄlu, 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…
Two types of quasinormal modes of Casadio-Fabbri-Mazzacurati brane-world black holes
Bekir Can LütfüoÄlu, 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…
