Enhanced Asymptotic Analysis of Continuous-Time Markov Branching Systems: Revisiting Limiting Structural Theorems

Azam A Imomov, Sarvar B. Iskandarov, Jakhongir B. Azimov +1

Markov branching systems form a fundamental class of stochastic models that are extensively applied in biology, physics, finance, and other domains. These systems are distinguished…

Observational constraints on viscous cosmology in gravity

M. Koussour, Alnadhief H. A. Alfedeel, S. Muminov +1

We investigate the late-time cosmic acceleration within the framework of viscous gravity, where the gravitational action depends on both the torsion scalar and the m…

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…

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…

Gravitational Spectra and Wave Propagation in Regular Black Holes Supported by a Dehnen Halo

Bekir Can Lütfüoğlu, Abubakir Shermatov, Javlon Rayimbaev +2

We investigate gravitational perturbations, quasinormal modes, grey-body factors, and absorption cross-sections of the recently proposed regular and asymptotically flat black hole…
