Non-linear instability of the Kerr Cauchy horizon near
Sebastian Gurriaran
We consider solutions of the Einstein vacuum equations which arise from smooth initial data on a hypersurface slightly inside a dynamical black hole settling down to a subextremal…

Precise asymptotics of the spin Teukolsky field in the Kerr black hole interior
Sebastian Gurriaran
Using a purely physical-space analysis, we prove the precise oscillatory blow-up asymptotics of the spin Teukolsky field in the interior of a subextremal Kerr black hole. In p…

Generic linearized curvature singularity at the perturbed Kerr Cauchy horizon
Sebastian Gurriaran
We prove the precise asymptotics of the spin Teukolsky field in the interior and along the Cauchy horizon of a subextremal Kerr black hole. Together with the oscillatory blow-…
