On Generalized (Conformal) Killing Tensors
Cynthia Arias, David KopÄan, David Kubiznak +1
We study higher-rank generalized Killing tensors with mixed symmetries, providing a couple of examples and applications. It is shown that such objects naturally exist in higher-dim…
From (Hidden) Symmetries to Stealth Solutions
David Kubiznak, Robert B. Mann, Marek MiliÄka
In a recent paper, Arxiv:2605.23077, we have demonstrated that (conformal) Killing vectors give rise to stealth vector solutions of a specific bumblebee-type Proca theory supplemen…
Proca-type Hair of Rotating Black Holes in Higher Dimensions
David Kubiznak, Robert B. Mann, Marek MiliÄka
We show that spacetime symmetries on any background give rise to stealth vector fields obeying Proca-type equations supplemented by curvature terms. This observation, which is true…
Bertotti-Robinson and Bonnor-Melvin universes in nonlinear electrodynamics
David Kubiznak, Otakar Svitek, Tayebeh Tahamtan
We review the status of Birkhoff's theorem in the presence of nonlinear electrodynamics (NLE) - extending the analysis to the case without asymptotic flatness. This leads to the Be…
On mass inflation and thin shells in quasi-topological gravity
Francesco Di Filippo, David Kubiznak, Aravindhan Srinivasan
We study the null junction conditions in (re-summed) quasi-topological gravity theories, showing that no null thin shells exist within the realms of standard distributional theory…
Hidden symmetries and separability structures of Ovcharenko-Podolský and conformal-to-Carter spacetimes
Finnian Gray, David Kubiznak, Hryhorii Ovcharenko +1
Recently, a remarkable new class of spacetimes describing black holes immersed in a non-aligned electromagnetic field has been found. While still of type D, this class goes beyond…
