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…

Nonlinear evolution of anisotropic matter configurations under higher-order curvature corrections

A. Zahra, S. A. Mardan, Muhammad Bilal Riaz +4

This study examines the dynamical evolution of self-gravitating systems in the presence of exotic matter within the framework of gravity. Specifically, we have adopted the S…

Gravitational wave radiation from periodic orbits and quasi-periodic oscillations in Einstein non-linear Maxwell-Yukawa black hole

Tehreem Zahra, Oreeda Shabbir, Bushra Majeed +3

In this article, we investigate the orbital dynamics and quasi-periodic oscillations (QPOs) surrounding a static, spherically symmetric geometry of an Einstein-nonlinear Maxwell-Yu…

Proper-Time Approach in Asymptotic Safety via Black Hole Quasinormal Modes and Grey-body Factors

Bekir Can Lütfüoğlu, Erdinç Ulaş Saka, Abubakir Shermatov +3

We study the quasinormal mode spectrum and grey-body factors of black holes in an effectively quantum-corrected spacetime, focusing on the influence of near-horizon modifications o…

Gravitational quasinormal modes of Dymnikova black holes

Bekir Can Lütfüoğlu, Erdinç Ulaş Saka, Abubakir Shermatov +3

We investigate gravitational quasinormal modes of the Dymnikova black hole, a regular spacetime in which the central singularity is replaced by a de Sitter core. This geometry, ori…
