Optical 2-metrics of Schwarzschild-Tangherlini Spacetimes and the Bohlin-Arnold Duality
Stephen Casey
We consider the projection of null geodesics of the Schwarzschild-Tangherlini metric in n+1 dimensions to the space of orbits of the static Killing vector where the motion of a giv…

Kastor-Traschen Black Holes, Null Geodesics and Conformal Circles
Stephen Casey
The Kastor-Traschen metric is a time-dependent solution of the Einstein-Maxwell equations with positive cosmological constant which can be used to describe an arbitrary number…

Optical Metrics and Projective Equivalence
Stephen Casey, Maciej Dunajski, Gary Gibbons +1
Trajectories of light rays in a static spacetime are described by unparametrised geodesics of the Riemannian optical metric associated with the Lorentzian spacetime metric. We inve…
