Gravitational perturbations of a regular T-duality inspired black hole: Quasinormal modes, excitation factors, and time-domain evolution

Bekir Can Lütfüoğlu, Mardon Abdullaev, Javlon Rayimbaev +2

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…

Phase transition for a black hole with matter fields and the relation with the Lyapunov exponent

Pakhlavon Yovkochev, Bobomurat J. Ahmedov, Bum-Hoon Lee +2

We construct static black hole solutions coexisting with anisotropic matter in asymptotically (anti-)de Sitter spacetime and investigate how the matter field modifies their thermod…

Spinning Particles around Einstein-Geometric Proca AdS Compact Objects

Gulzoda Rakhimova, Beyhan Puliçe, Elham Ghorani +2

We investigate the dynamics of spinning test particles in the vicinity of Einstein--geometric Proca (EGP) Anti-de Sitter (AdS) compact objects, which arise from metric-Palatini gra…

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…
