Quasinormal modes of noncommutative geometry-inspired dirty black holes
arXiv:2507.19107 · doi:10.1098/rspa.2025.0021
Abstract
We investigate the quasinormal modes (QNMs) of noncommutative geometry-inspired dirty black holes, focusing on both non-extremal and extremal configurations. These gravitational objects, characterized by smeared energy distributions within a modified de Sitter-like equation of state, modify the classical Schwarzschild metric and regularize central singularities. We employ a spectral method based on Chebyshev polynomials to solve the eigenvalue problem for scalar, electromagnetic, and gravitational perturbations. Our results reveal new overdamped modes indicative of rapid decay without oscillation, particularly prominent in near-extremal and extremal regimes. Additionally, we establish that the QNMs converge to classical Schwarzschild values for large mass parameters, validating our method's robustness. Our findings highlight the impact of dirtiness and noncommutative effects on black hole QNM spectra, offering potential observational signatures for distinguishing these objects in gravitational-wave detections.
