Probing the nature of Einstein nonlinear Maxwell Yukawa black hole through gravitational wave forms from periodic orbits and quasiperiodic oscillations

Oreeda Shabbir, Abubakir Shermatov, Bushra Majeed +3

In this work, we study gravitational wave emission from periodic orbits of test particles, analyze quasi periodic oscillations, and constrain the parameters of the static, spherica…

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…

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…

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…
