 Abstract: We study Bayesian inference of black hole ringdown modes for simulated binary
black hole signals. We consider to what extent different fundamental ringdown
modes can be identified in the context of black hole spectroscopy. Our
simulated signals are inspired by the high mass event GW190521. We find strong
correlation between mass ratio and Bayes factors of the subdominant ringdown
modes. The Bayes factor values and time dependency, and the peak time of the
(3,3,0) mode align with those found analysing the real event GW190521,
particularly for high-mass ratio systems.
