We describe early success in the evolution of binary black-hole spacetimes with a numerical code based on a generalization of harmonic coordinates. Indications are that with sufficient resolution this scheme is capable of evolving binary systems for enough time to extract information about the orbit, merger, and gravitational waves emitted during the event. As an example we show results from the evolution of a binary composed of two equal mass, nonspinning black holes, through a single plunge…

Simulation of binary black hole spacetimes with a harmonic evolution scheme
A numerical solution scheme for the Einstein field equations based on generalized harmonic coordinates is described, focusing on details which are not provided before in the literature and which are
Analytical Black-Hole Binary Merger Waveforms.
This model agrees with the most accurate numerical relativity results to within their own uncertainties throughout the merger-ringdown phase, and it does so for example cases spanning the full range of binary parameter space that is currently testable with numerical relativity.
Close encounters of three black holes
We present the first fully relativistic long-term numerical evolutions of three equal-mass black holes in a system consisting of a third black hole in a close orbit about a black-hole binary. These
Dynamics of black holes in de Sitter spacetimes
Nonlinear dynamics in cosmological backgrounds has the potential to teach us immensely about our Universe, and also to serve as prototype for nonlinear processes in generic curved spacetimes. Here we
Binary black-hole evolutions of excision and puncture data
We present a new numerical code developed for the evolution of binary black-hole spacetimes using different initial data and evolution techniques. The code is demonstrated to produce state-of-the-art
Dynamics of marginally trapped surfaces in a binary black hole merger: Growth and approach to equilibrium
The behavior of quasi-local black hole horizons in a binary black hole merger is studied numerically. We compute the horizon multipole moments, fluxes and other quantities on black hole horizons
Black hole mergers and unstable circular orbits
We describe recent numerical simulations of the merger of a class of equal mass, non-spinning, eccentric binary black hole systems in general relativity. We show that with appropriate fine tuning of
Gravitational-wave imaging of black hole horizons: Post-merger chirps from binary black holes
The merger of a binary black hole gives birth to a highly distorted remnant black hole that relaxes to its final state by emitting gravitational waves. During this fraction of a second, space-time
Puncture Initial Data and Evolution of Black Hole Binaries with High Speed and High Spin
This dissertation explores numerical models of the orbit, inspiral, and merger phases of black hole binaries. We focus on the astrophysically realistic case of black holes with nearly extremal spins,
Accurate evolution of orbiting binary black holes.
A detailed analysis of binary black hole evolutions in the last orbit is presented and consistent and convergent results for the trajectories of the individual bodies are demonstrated.
