Interactive tool for visualizing spherical/circular photon orbits in Kerr
We show that an eccentric binary of black holes with misaligned spins is integrable at 2PN order. We also construct 4 out of 5 action variables at 1.5PN.
Brans-Dicke theory in Bondi-Sachs form: Asymptotically flat solutions, asymptotic symmetries and gravitational-wave memory effects
We study the structure of asymptotic null infinity in the Brans-Dicke theory of gravity
Merger dynamics create an attractive fixed-point in the space of distributions
Last week I gave an invited talk at the Spring 2020 workshop of the Black Hole Perturbation Toolkit (BHPToolkit). The BHPToolkit is a collection of open sou...
The first astrophysically-relevant numerical simulation of merging black holes in a higher-curvature theory beyond GR.
