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…

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…

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…

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…

Constraining -Exponential Inflation with the latest ACT observations

Jureeporn Yuennan, Farruh Atamurotov, Salvatore Capozziello +1

Recent observations from the Atacama Cosmology Telescope (ACT), especially when combined with DESI baryon acoustic oscillation data, indicate a scalar spectral index higher t…

Horizon-Brightened Acceleration Radiation and Optical Signatures of Generic Regular Black Holes from Nonlinear Electrodynamics

Uktamjon Uktamov, Ali Övgün, Reggie C. Pantig +1

We investigate horizon-brightened acceleration radiation (HBAR) and optical signatures for a broad class of regular black holes sourced by nonlinear electrodynamics. The spacetimes…

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…

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…
