Spin-orbit precession for eccentric black hole binaries at first order in the mass ratio
Sarp Akcay, David Dempsey, Sam Dolan
We consider spin-orbit ("geodetic") precession for a compact binary in strong-field gravity. Specifically, we compute , the ratio of the accumulated spin-precession and orbital…
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…
Stability of gravitating charged-scalar solitons in a cavity
Supakchai Ponglertsakul, Elizabeth Winstanley, Sam R. Dolan
We present new regular solutions of Einstein-charged scalar field theory in a cavity. The system is enclosed inside a reflecting mirror-like boundary, on which the scalar field van…
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).…
Waves and null congruences in a draining bathtub
David Dempsey, Sam R Dolan
We study wave propagation in a draining bathtub: a fluid-mechanical black hole analogue in which perturbations are governed by a Klein-Gordon equation on an effective Lorentzian ge…
