Gravitational Instantons and special geometry
Steffen Aksteiner, Lars Andersson
The Chen-Teo gravitational instanton is an asymptotically flat, toric, Ricci flat family of metrics on , that provides a counterexample to the…

On the geometry of Petrov type II spacetimes
Steffen Aksteiner, Lars Andersson, Bernardo Araneda +1
In general, geometries of Petrov type II do not admit symmetries in terms of Killing vectors or spinors. We introduce a weaker form of Killing equations which do admit solutions. I…

All local gauge invariants for perturbations of the Kerr spacetime
Steffen Aksteiner, Thomas Bäckdahl
We present two complex scalar gauge invariants for perturbations of the Kerr spacetime defined covariantly in terms of the Killing vectors and the conformal Killing-Yano tensor of…
