  journal={Physical Review D},
We present improved post-Newtonian-inspired initial data for nonspinning black-hole binaries, suitable for numerical evolution with punctures. We revisit the work of Tichy et al. [W. Tichy, B. Brugmann, M. Campanelli, and P. Diener, Phys. Rev. D 67, 064008 (2003).], explicitly calculating the remaining integral terms. These terms improve accuracy in the far zone and, for the first time, include realistic gravitational waves in the initial data. We investigate the behavior of these data both at…

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,

Post-Newtonian initial data with waves: progress in evolution

In Kelly et al (2007 Phys. Rev. D 76 024008), we presented new binary black-hole initial data adapted to puncture evolutions in numerical relativity. These data satisfy the constraint equations to

Binary black hole evolutions of approximate puncture initial data

Approximate solutions to the Einstein field equations are valuable tools to investigate gravitational phenomena. An important aspect of any approximation is to investigate and quantify its regime of

Status of black-hole-binary simulations for gravitational-wave detection

It is now possible to theoretically calculate the gravitational-wave (GW) signal from the inspiral, merger and ringdown of a black-hole-binary system. The late inspiral, merger and ringdown can be

Hybrid black-hole binary initial data

Traditional black-hole (BH) binary puncture initial data is conformally flat. This unphysical assumption is coupled with a lack of radiation signature from the binary's past life. As a result,

Alternatives to standard puncture initial data for binary black hole evolution

Standard puncture initial data have been widely used for numerical binary black hole evolutionsdespite their shortcomings, most notably the inherent lack of gravitational radiation at the initialtime

Conformally curved binary black hole initial data including tidal deformations and outgoing radiation

By asymptotically matching a post-Newtonian (PN) metric to two perturbed Schwarzschild metrics, we generate approximate initial data (in the form of an approximate 4-metric) for a nonspinning black

Reducing spurious gravitational radiation in binary-black-hole simulations by using conformally curved initial data

At early times in numerical evolutions of binary black holes, current simulations contain an initial burst of spurious gravitational radiation (also called ‘junk radiation’) which is not

Numerical black hole initial data with low eccentricity based on post-Newtonian orbital parameters

Black hole binaries on noneccentric orbits form an important subclass of gravitational wave sources, but it is a nontrivial issue to construct numerical initial data with minimal initial eccentricity

Initial data transients in binary black hole evolutions

We describe a method for initializing characteristic evolutions of the Einstein equations using a linearized solution corresponding to purely outgoing radiation. This allows for a more consistent
