Spectral instability of black holes: relating the frequency domain to the time domain
Yiqiu Yang, Zhan-Feng Mai, Run-Qiu Yang +2
Recent work has shown that the quasinormal mode spectrum of black holes is unstable under small perturbations (of order ) of the radial potential, while the early time-domain ri…
