Rotating Extremal Black Holes in Einstein-Born-Infeld Theory
Tomáš Hale, Robie A. Hennigar, David Kubizňák
We construct exact solutions that describe the near horizon region of extremal rotating black holes in Einstein-Born-Infeld theory. Using generalized Komar integrals, we extract th…

Excising Cauchy Horizons with Nonlinear Electrodynamics
Tomáš Hale, Robie A. Hennigar, David Kubiznak
Charged and/or rotating black holes in General Relativity feature Cauchy horizons, which indicate a breakdown of predictability in the theory. Focusing on spherically symmetric cha…

Optical properties of black holes in regularized Maxwell theory
Tomas Hale, David Kubiznak, Jana Menšíková
Regularized Maxwell electrodynamics is a recently discovered theory of non-linear electrodynamics, with a "minimally regularized" field strength of a point charge, that is "very cl…
