- background In recent years, breakthrough progress in gravitational- wave detections and black hole imaging observations has opened new avenues for probing the spacetime structure in the strong-gravity regime. In 2015, the LIGO Scientific Collaboration reported the first direct detection of gravi- tational waves generated by the merger of a binary black hole system [1]. In the ringdown phase after a black hole merger, or in the late-time evolution of a perturbed black hole, the system returns to equilibrium
- background Due to the nature of BHs, they must be studied through gravitational interactions with their sur- roundings, as direct observation is impossible. In the quest for observational evidence confirming the existence of BHs in nature, the detection of gravitational waves provides by the LIGO collaboration robust support for the existence of stellar-mass BHs [ 1]. Regarding supermassive BHs, re- search focuses on the study of galactic nuclei. Type I and II Seyfert galaxies present evidence pointing to t
- background 21622v1 [gr-qc] 23 Apr 2026 1 Introduction Black holes are among the most fascinating objects in modern astrophysics, with their existence supported by a growing body of observational evidence. This is evidenced by gravitational-wave signals from binary black hole mergers captured by the Laser Interferometer Gravitational-Wave Observatory (LIGO) [1], as well as the shadow images of M87* and the Milky Way's center Sgr A* obtained by the EHT [2, 3]. These discoveries not only validate the predicti
