Scalar-Tensor theory as a singular subsector of Λ(ϕ) Plebanski gravity
D. Beke
It is shown that, in the absence of matter fields, the coupling of a scalar field to the non-chiral Plebanski action can be obtained by relaxing the trace component of the simplici…

Killing spinor space-times and constant-eigenvalue Killing tensors
D. Beke, N. Van den Bergh, L. Wylleman
A class of Petrov type D Killing spinor space-times is presented, having the peculiar property that their conformal representants can only admit Killing tensors with constant eigen…

Expanding perfect fluid generalizations of the C-metric
Lode Wylleman, David Beke
We reexamine Petrov type D gravitational fields generated by a perfect fluid with spatially homogeneous energy density and in which the flow lines form a timelike non-shearing and…
