abstract
We study the quasi-normal modes of the charged scalar perturbations in the background of the Einstein-Maxwell-aether black hole through three methods (WKB method, continued fraction method, generalized eigenvalue method). Then we propose the specific treatment for the generalized effective potential with $\omega$-dependence and the complete procedure of transforming calculation continued fraction method into finding the zero point of the corresponding complex function numerically. These methods are valid because the results from different methods are consistent. We also investigate the allowed region of the second kind aether black hole among the system parameters ($c_{13},c_{14},Q$). Finally we show the existence of quasi-resonances of massive perturbation for Einstein-Maxwell-aether black hole even with large aether parameter.

Long-Lived Quasinormal Modes and Quasi-Resonances around Non-Minimal Einstein-Yang-Mills Black Holes
Massive scalar fields around non-minimal Einstein-Yang-Mills black holes can form arbitrarily long-lived quasi-resonances in flat space, but not in de Sitter space; an analytic large-mass frequency formula is given.

Gravitational quasinormal modes of the Hayward spacetime
Gravitational quasinormal modes of the Hayward black hole are computed with WKB and time-domain methods, showing that the quantum parameter gamma raises frequencies, weakens damping, and acts slightly more on the firs...
