Quasinormal modes of rapidly rotating Ellis-Bronnikov wormholes

We present for the first time a study of the quasinormal modes of rapidly rotating Ellis-Bronnikov wormholes in general relativity. We compute the spectrum of the wormholes using a spectral decomposition of the metric perturbations on a numerical background. We focus on the M-z = 2, 3 sector of the perturbations, and show that the triple isospectrality of the symmetric and static Ellis-Bronnikov wormhole is broken due to rotation, giving rise to a much richer spectrum than the spectrum of Kerr black holes. We do not find any instabilities for M-z = 2, 3 perturbations.
