On equipotential photon surfaces in (electro-)static spacetimes of arbitrary dimension
Carla Cederbaum, Sophia Jahns, Olivia Vičánek Martínez
We study timelike, totally umbilic hypersurfaces -- called photon surfaces -- in -dimensional static, asymptotically flat spacetimes, for . First, we give a complete…

Photon sphere uniqueness in higher-dimensional electrovacuum spacetimes
Sophia Jahns
We show a uniqueness result for the n-dimensional spatial Reissner-Nordström manifold: a static, electrovacuum, asymptotically flat system which is asymptotically Reissner-Nordströ…

Geometry and topology of the Kerr photon region in the phase space
Carla Cederbaum, Sophia Jahns
We study the set of trapped photons of a subcritical (a<M) Kerr spacetime as a subset of the phase space. First, we present an explicit proof that the photons of constant Boyer--Li…
