On Universal Black Holes
Hervik, Sigbjørn; Ortaggio, Marcello (Peer reviewed; Journal article, 2020)Recent results on universal black holes in d dimensions are summarized. These are static metrics with an isotropy-irreducible homogeneous base space which can be consistently employed to construct solutions to virtually ... -
Universal Black Holes
Hervik, Sigbjørn; Ortaggio, Marcello (Peer reviewed; Journal article, 2020-02)We prove that a generalized Schwarzschild-like ansatz can be consistently employed to construct d-dimensional static vacuum black hole solutions in any metric theory of gravity for which the Lagrangian is a scalar invariant ... -
Universal p-form black holes in generalized theories of gravity
Hervik, Sigbjørn; Ortaggio, Marcello (Peer reviewed; Journal article, 2020-10)We explore how far one can go in constructing d-dimensional static black holes coupled to p-form and scalar fields before actually specifying the gravity and electrodynamics theory one wants to solve. At the same time, we ...
