Description
In this talk, we investigate the horizon structure of accelerating black holes described by the C-metric, including its superaccelerating limit. We then analyze the stability of the Cauchy horizon in these configurations using Christodoulou’s formulation of Strong Cosmic Censorship.
To this end, we classify the families of quasinormal modes of the spacetime and study their properties for scalar, electromagnetic, and fermionic perturbations.
Our results show that Strong Cosmic Censorship can be violated in near-extremal regimes for scalar and electromagnetic perturbations, while it appears to be preserved for fermionic perturbations. Moreover, we identify horizon configurations with non-near-extremal charge that also violate Strong Cosmic Censorship.
