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…
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…
Collins in Wonderland
Ben David Normann, Sigbjørn Hervik
What is the asymptotic future of a scalar-field model if the assumption of isotropy is relaxed in generic, homogeneous space-times with general relativity? This paper is a continua…
A study of inhomogeneous massless scalar gauge fields in cosmology
Ben David Normann, Sigbjørn Hervik, Angelo Ricciardone +1
Why is the Universe so homogeneous and isotropic? We summarize a general study of a -law perfect fluid alongside an inhomogeneous, massless scalar gauge field (with homogeneous…
