Anomalous decay rate of quasinormal modes in Reissner-Nordström black holes

The anomalous decay rate of the quasinormal modes occurs when longest-lived are ones with higher angular number. Such behaviour has been recently studied in different static spacetimes, for scalar and fermionic perturbations, being observed both cases. In this work, we extend existent studies to charged namely, Reissner-Nordstr\"om, Reissner-Nordstr\"om-de Sitter Reissner-Nordstr\"om-Anti-de black holes. We show that field perturbations is present every geometry photon sphere modes, existence a critical mass whenever $\Lambda \geq 0$. general, value increases raise hole charge, thus rendering minimum Schwarzschild limit. also study dominant mode/family massless massive these geometries showing non-trivial dominance spectra depends on charge.
