Robust gauge conditions are critically important to the stability and accuracy of numerical relativity (NR) simulations involving compact objects. Most of the NR community use the highly robust---though decade-old---moving-puncture (MP) gauge conditions for such simulations. It has been argued that in binary black hole (BBH) evolutions adopting this gauge, noise generated near adaptive-mesh-refinement (AMR) boundaries does not converge away cleanly with increasing resolution, severely limiting… 
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,
Analyzing Binary Black hole Spacetimes
With the first ever detection of gravitational waves from merging black-hole binaries by LIGO (Laser Interferometer GravitationalWave Observatory), a new era of gravitational wave astronomy was
Bona-Masso slicing conditions and the lapse close to black-hole punctures
We consider several families of functions f(α) that appear in the Bona-Masso slicing condition for the lapse function α. Focusing on spherically symmetric and time-independent slices we apply these
Numerical relativity in spherical coordinates with the Einstein Toolkit
Numerical relativity codes that do not make assumptions on spatial symmetries most commonly adopt Cartesian coordinates. While these coordinates have many attractive features, spherical coordinates
SENR/NRPy+: Numerical Relativity in Singular Curvilinear Coordinate Systems
For the first time, nearly exponential convergence of constraint violation and gravitational waveform errors to zero is demonstrated as the order of spatial finite difference derivatives is increased, while holding the spherical-like coordinate grids fixed at moderate resolution.
Energy Density of Gravitational Field in General Transverse Gauge
In this paper, firstly, we will prove there is a general transverse gauge in general relativity for linear approximation. This gauge condition can play the same role as the radiation gauge condition
General Relativistic Simulations of the Quasicircular Inspiral and Merger of Charged Black Holes: GW150914 and Fundamental Physics Implications.
It is shown that the inspiral is most efficient for detecting black hole charge through gravitational waves and that GW150914 is compatible with having charge-to-mass ratio as high as 0.3.
Comparing an analytical spacetime metric for a merging binary to a fully nonlinear numerical evolution using curvature scalars
We introduce a new geometrically invariant prescription for comparing two different spacetimes based on geodesic deviation. We use this method to compare a family of recently introduced analytical
Exploring New Physics Frontiers Through Numerical Relativity
Techniques for solving Einstein’s equations in generic spacetimes are reviewed, focusing on fully nonlinear evolutions but also on how to benchmark those results with perturbative approaches.

Binary Black Holes in Quasi-Stationary Circular Orbits
We propose a method of determining solutions to the constraint equations of General Relativity approximately describing binary black holes in quasi-stationary circular orbits. Black holes with
An efficient spectral interpolation routine for the TwoPunctures code
A new publicly-available spectral interpolationoutine is announced that improves the performance of the original interpolation routine by a factor of ~100, yielding results consistent with the original spectral interpolations routine to roundoff precision.
Numerical Relativity: Solving Einstein's Equations on the Computer
Numerical relativity is one of the major fields of contemporary general relativity and is developing continually. Yet three years ago, no textbook was available on this subject. The first textbook
however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)
