Abstract: It has long been suggested that the Cauchy horizon of dynamical black holes is subject to a weak null singularity, under the mass inflation scenario. We study in spherical symmetry the Einstein–Maxwell–Klein–Gordon equations and while… read more here.

Abstract: We show that generic linear perturbations ψ solving □gψ+αl2ψ=0 on Reissner–Nordström–AdS black holes have infinite local energy at the Cauchy horizon. Combined with the result of Kehle (2020 Commun. Math. Phys. 376 145–200) that such… read more here.

Abstract: We investigate a stress-energy tensor for a CFT at strong coupling inside a small five-dimensional rotating Myers-Perry black hole with equal angular momenta by using the holographic method. As a gravitational dual, we perturbatively construct… read more here.

Abstract: We solve the 2+1-dimensional Teukolsky equation numerically for the Weyl scalars $\psi_0$ and $\psi_4$ along a time-like geodesic approaching the Cauchy horizon of a rapidly rotating perturbed Kerr black hole. We find that both the… read more here.

DOI: 10.1215/00127094-3715189
Abstract: It has long been suggested that solutions to linear scalar wave equation $$\Box_g\phi=0$$ on a fixed subextremal Reissner-Nordstr\"om spacetime with non-vanishing charge are generically singular at the Cauchy horizon. We prove that generic smooth and… read more here.
