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 has enabled us to compute accurate waveforms from the merger stage also. This has an important impact on the search for gravitational waves from binary black holes. ‘Complete’ binary black-hole wavef...
متن کاملOn the accuracy and precision of numerical waveforms: Effect of waveform extraction methodology
We present a new set of 95 numerical relativity simulations of non-precessing binary black holes (BBHs). The simulations sample comprehensively both black-hole spins up to spin magnitude of 0.9, and cover mass ratios 1 to 3. The simulations cover on average 24 inspiral orbits, plus merger and ringdown, with low initial orbital eccentricities e < 10−4. A subset of the simulations extends the cov...
متن کاملValidating the effective-one-body model of spinning, precessing binary black holes against numerical relativity
In Abbott et al. [Phys. Rev. X 6, 041014 (2016)], the properties of the first gravitational wave detected by LIGO, GW150914, were measured by employing an effective-one-body (EOB) model of precessing binary black holes whose underlying dynamics and waveforms were calibrated to numerical-relativity (NR) simulations. Here, we perform the first extensive comparison of such an EOBNR model to 70 pre...
متن کاملData formats for numerical relativity waves
While this interface document proposes technical standards for numerical relativity waveforms, we believe that the ability to extract the best astrophysical information from NR waveforms in gravitational wave searches will depend not just on adopting standards, but on the ability of the gravitational wave detector communities and the NR relativity communities to interact closely and develop a s...
متن کاملStatus of black-hole-binary simulations for gravitational-wave detection
It is now possible to theoretically calculate the gravitational-wave signal from the inspiral, merger and ringdown of a black-hole-binary system. The late inspiral, merger and ringdown can be calculated in full general relativity using numerical methods. The numerical waveforms can then be either stitched to inspiral waveforms predicted by approximation techniques (in particular postNewtonian c...
