Stable photon orbits in stationary axisymmetric spacetimes with an electromagnetic field and a cosmological constant
Jake O. Shipley
Stable light rings, which are associated with spacetime instabilities, are known to exist in four-dimensional stationary axisymmetric spacetimes that solve the Einstein-Maxwell equ…

Strong-field gravitational lensing by black holes
Jake O. Shipley
In this thesis we study aspects of strong-field gravitational lensing by black holes in general relativity, with a particular focus on the role of integrability and chaos in geodes…

Wada structures in a binary black hole system
Álvar Daza, Jake O. Shipley, Sam R. Dolan +1
A key goal of the Event Horizon Telescope is to observe the shadow cast by a black hole. Recent simulations have shown that binary black holes, the progenitors of gravitational wav…
