報告摘要：
We investigate Bayesian inference in the context of black hole ringdown modes for simulated binary black hole signals. We aim to determine the degree to which various essential ringdown modes can be distinguished when conducting black hole spectroscopy. The basis for our simulated signals is the notable high-mass event GW190521. Our findings reveal a significant connection between the mass ratio and the Bayes factors associated with the secondary ringdown modes. Furthermore, our analysis shows that the Bayes factor values, their temporal evolution, and the peak time of the (3,3,0) mode closely align with those observed in the analysis of the actual event GW190521, especially in high-mass ratio systems.?
