Gravitational perturbations from NHEK to Kerr
Alejandra Castro, Victor Godet, Joan Simón +2
We revisit the spectrum of linear axisymmetric gravitational perturbations of the (near-)extreme Kerr black hole. Our aim is to characterise those perturbations that are responsibl…

Breaking away from the near horizon of extreme Kerr
Alejandra Castro, Victor Godet
We study gravitational perturbations around the near horizon geometry of the (near) extreme Kerr black hole. By considering a consistent truncation for the metric fluctuations, we…
