Ringing Astrophysical Black Holes: Environmental Effects on Quasinormal Modes
Anotace anglicky
The advent of gravitational wave astronomy has opened new opportunities for probing the fundamental properties of black holes (BHs) and testing the nature of gravity. Among the most promising methods is the so-called BH spectroscopy, which utilizes the characteristic ringing of BHs described by quasinormal modes (QNMs)–a set of exponentially damped oscillations. Deviations from the distinctive QNM spectrum of a Kerr BH could challenge general relativity and significantly deepen our understanding of BHs. However, real astrophysical BHs are not isolated. They reside in some astrophysical environment, such as an accretion disc, or dark matter halo which modifies the spacetime geometry and, consequently, affects QNMs. This project aims to advance our understanding of the environmental effects and analyze their spectral features in QNM spectrum. Ultimately, we aim to assess the robustness of black hole spectroscopy as a tool for fundamental physics by determining whether imprints of theories beyond general relativity can be disentangled from those caused by astrophysical environments.
