Stability conditions for light rings in circular stationary axisymmetric spacetimes
Jake O. Shipley
We consider the stability of light rings in four-dimensional circular stationary axisymmetric spacetimes. Using a Hamiltonian formalism for null geodesics and the Killing symmetrie…
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…
Stable photon orbits in stationary axisymmetric electrovacuum spacetimes
Sam R Dolan, Jake O Shipley
We investigate the existence and phenomenology of stable photon orbits (SPOs) in stationary axisymmetric electrovacuum spacetimes in four dimensions. First, we review the classific…
Binary black hole shadows, chaotic scattering and the Cantor set
Jake O Shipley, Sam R Dolan
We investigate the qualitative features of binary black hole shadows using the model of two extremally charged black holes in static equilibrium (a Majumdar--Papapetrou solution).…
