Nonradial perturbations of static charged wormholes
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
We investigate the nonradial quasinormal-mode spectrum of static charged Ellis--Bronnikov wormholes in Einstein--Maxwell theory minimally coupled to a phantom scalar field. The bac…
Hierarchy of Angular Instabilities in Scalarized Black Holes
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
We investigate the stability of scalarized black holes in Einstein-scalar-Gauss-Bonnet-Ricci theory along their fundamental branches. We show that initially stable solutions first…
Radial perturbations of charged wormholes
Jose Luis Blázquez-Salcedo, Luis Manuel González-Romero, Fech Scen Khoo +2
Ellis-Bronnikov wormholes suffer from an unstable radial mode. Here we investigate the evolution of the unstable mode(s) for charged wormholes. We show that the instability remains…
Quasinormal modes of rapidly rotating Ellis-Bronnikov wormholes
Fech Scen Khoo, Bahareh Azad, Jose Luis Blázquez-Salcedo +4
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…
Quasinormal modes of Kerr black holes using a spectral decomposition of the metric perturbations
Jose Luis Blázquez-Salcedo, Fech Scen Khoo, Jutta Kunz +1
We report a new method to calculate the quasinormal modes of rotating black holes, using a spectral decomposition to solve the partial differential equations that result from intro…
