We present new ideas for evolving black holes through a computational grid without excision, which enable accurate and stable evolutions of binary black hole systems with the accurate determination of gravitational waveforms directly from the wave zone region. Rather than excising the black hole interiors, our approach follows the "puncture" treatment of black holes, but utilizing a new gauge condition which allows the black holes to move successfully through the computational domain. We apply…

Gravitational-wave data analysis using binary black-hole waveforms
While the inspiral and ring-down stages of the binary black-hole coalescence are well modelled by analytical approximation methods in general relativity, the recent progress in numerical relativity
Improved analytical description of inspiralling and coalescing black-hole binaries
We present an analytical formalism, within the effective-one-body framework, which predicts gravitational-wave signals from inspiralling and coalescing black-hole binaries that agree, within
Binary Black Holes, Gravitational Waves, and Numerical Relativity
The final merger of comparable mass binary black holes produces an intense burst of gravitational radiation and is one of the strongest sources for both ground-based and space-based gravitational
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
A phenomenological template family for black-hole coalescence waveforms
Recent progress in numerical relativity has enabled us to model the non-perturbative merger phase of the binary black-hole coalescence problem. Based on these results, we propose a phenomenological
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
Spacelike gravitational radiation extraction from rotating binary black holes
We introduce an alternate method for gravitational radiation extraction for binary black hole mergers where we do not use a single extraction radius at the intermediate field region but instead use a
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
Modeling Flows Around Merging Black Hole Binaries
Coalescing massive black hole binaries are produced by the mergers of galaxies. The final stages of the black hole coalescence produce strong gravitational radiation that can be detected by the

The inspiral and merger of two orbiting black holes is among the most promising sources for the first (hopefully imminent) direct detection of gravitational waves (GWs), and measurements of these
