Left-invariant Pseudo-Riemannian metrics on Lie groups: The null cone II
Sigbjørn Hervik
We continue to study left-invariant pseudo-Riemannian metrics on Lie groups being in the null cone of the -action using the moving bracket approach. In particular, the Lie…
Opening Pandora's box: Kundt solutions to Conformal Killing Gravity
Sigbjorn Hervik, Edmar G. Pantohan
We consider Kundt solutions to vacuum Conformal Killing Gravity (CKG) proposed by Harada and find numerous solutions in four dimensions and in higher dimensions. In CKG theory the…
Left-invariant Pseudo-Riemannian metrics on Lie groups: The null cone
Sigbjorn Hervik
We study left-invariant pseudo-Riemannian metrics on Lie groups using the bracket flow of the corresponding Lie algebra. We focus on metrics where the Lie algebra is in the null co…
Universal -form black holes in generalized theories of gravity
Sigbjørn Hervik, Marcello Ortaggio
We explore how far one can go in constructing -dimensional static black holes coupled to -form and scalar fields before actually specifying the gravity and electrodynamics th…
On universal black holes
Sigbjørn Hervik, Marcello Ortaggio
Recent results of arXiv:1907.08788 on universal black holes in dimensions are summarized. These are static metrics with an isotropy-irreducible homogeneous base space which can…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
