Abstract

<p>The simplicity of black holes is guaranteed by the no-hair theorem in general relativity. Binary black hole mergers that lead to the emission of gravitational wave (GW) ringdown are important to test general relativity in the extreme gravity regime. The recent data analysis of GW ringdown revealed that we could extract the multiple quasi-normal modes of a black hole from GW ringdown with high accuracy if the emission of GW ringdown starts earlier. Also, it turned out that there is a universal feature of the excitation of multiple quasi-normal modes, which was confirmed by both the data analysis of simulated GW waveforms and the black hole perturbation theory. The emission of GW echo could be caused by quantum effects near black hole horizons and can be tested by the third-generation GW observatories.</p>
