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…
Thermodynamics of Einstein-Geometric Proca AdS compact objects
Asalkhon Alimova, Elham Ghorani, Beyhan Puliçe +2
In this study we explore metric-Palatini gravity extended by the antisymmetric component of the affine curvature. This gravitational theory results in general relativity plus a geo…
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…
New analytical model of rotating black hole with dark matter halo: constraints from EHT observations and accretion disk
Uktamjon Uktamov, Sanjar Shaymatov, Bobomurat Ahmedov +1
In this paper, we start from a static black hole (BH) immersed in a Deanne-type dark matter (DM) halo and employ the Newman-Janis algorithm (NJA) to generate the rotating black hol…
Lensing Stability and Scattering Phenomena in Anisotropic Black Hole Spacetimes in Plasma
Jonibek Khasanov, Mirzabek Alloqulov, Pankaj Sheoran +2
We investigate the physical and observational features of static, spherically symmetric black hole spacetimes surrounded by anisotropic fluid and embedded in a plasma environment.…
Exploring the Effects of Generalized Entropy onto Bardeen Black Hole Surrounded by Cloud of Strings
Hamza Tariq, Usman Zafar, Shahid Chaudhary +3
This work explores the thermodynamic characteristics and geothermodynamics of a Bardeen black hole (BH) that interacts with a string cloud and is minimally connected to nonlinear e…
Shadows and Optical Appearances of Black Holes in Gravity
Khadije Jafarzade, Sanjar Shaymatov, Mubasher Jamil
In this paper, we consider a charged AdS/dS black hole (BH) in gravity and study its optical features, including the shadow's geometrical shape and the energy emission rate…
