Abstract
We provide the most complete analysis so far of quasinormal modes of rotating bla .7$ and $\chi\sim 0.95$, depending on the mode. We report that overtones are overall more sensitive to corrections, which is expected from recent literature on this topic. We also discuss the limit of validity of the linear corrections to the quasinormal mode frequencies by estimating the size of nonlinear effects in the higher-derivative couplings. All our results are publicly available in an online repository.| File | Dimensione | Formato | |
