Gravitational perturbations of a regular T-duality inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution
Bekir Can LütfüoÄlu, Bekir Can Lütfüoğlu, Mardon Abdullaev +3
We study axial gravitational perturbations of the neutral regular black hole generated by a non-local, T-duality-inspired zero-point length and the associated gravitational self-en…
Eikonal Ringing, Shadows, Lensing, Grey-Body Factors, and Binding Energy of Asymptotically Flat Regular Black Holes in Phantom Dirac-Born-Infeld Gravity
Mardon Abdullaev, Gumisbek Allambergenov, Diyorbek Rashidov +2
We develop a geodesic-optics description of eikonal quasinormal ringing, blackhole shadows, strong lensing, grey-body factors (GBFs), and the binding energy of massive particles fo…
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…
Ringing Regularity: Gravitational Perturbations and Quasinormal Modes of Einasto-Supported Black Holes
Bekir Can LütfüoÄlu, Bekir Can Lütfüoğlu, Javlon Rayimbaev +3
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…
