Quasinormal modes of a quantum inspired black hole in four dimensions with cosmological constant

R. D. B. Fontana, Jeferson de Oliveira, B. Eslam Panah +1

We study the scalar and Dirac perturbations of quantum-corrected black holes with cosmological constant. Using two different methods (WKB and double-null characteristic integration…

Charged Black Holes in Einstein-- Gravity with Letelier--Alencar Cloud of Strings: Thermodynamics and QPO-Based Observational Constraints

B. Eslam Panah, Bidyut Hazarika, Prabwal Phukon

In this study, black hole solutions are derived within the framework of Einstein gravity, coupled to a gauge field in the presence of both the Letelier--Alencar \textit{clou…

Accelerating electrically charged ModMax black hole solutions in gravity

B. Eslam Panah, N. Heidari, A. Rincón

Using the metric in the context of gravity coupled with the ModMax nonlinear electromagnetic field (the ModMax theory), we derive an exact black hole solution in…

Optical and Thermodynamic Signatures of Lorentz Symmetry Breaking in Bumblebee AdS Black Holes

Behzad Eslam Panah, Abdullah Guvendi, Semra Gurtas Dogan +1

We investigate the impact of spontaneous Lorentz symmetry breaking on scalar wave propagation, null geodesics, and thermodynamic behavior of four-dimensional asymptotically AdS bla…

Thermodynamics, Phase Transitions, and Geodesic Structure of F(R)-Phantom Banados-Teitelboim-Zanelli (BTZ) Black Holes

Behzad Eslam Panah, Bilel Hamil, Manuel E. Rodrigues

This paper investigates phantom BTZ black holes within the high-curvature gravity theory framework, specifically using a special case of power-Maxwell theory, which functions as a…

Born-Infeld AdS Black Holes Surrounded by Perfect Fluid Dark Matter

Behzad Eslam Panah, Bilel Hamil, Manuel E. Rodrigues

We obtain exact charged AdS black hole solutions in Einstein Lambda gravity including the effects of Born Infeld nonlinear electrodynamics and Perfect Fluid Dark Matter. The influe…
