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…
