Searching for binary coalescences with inspiral templates
نویسندگان
چکیده
There has been remarkable progress in numerical relativity recently. This has led to the generation of gravitational waveform signals covering what has been traditionally termed the three phases of the coalescence of a compact binary— the inspiral, merger and ringdown. In this paper, we examine the usefulness of inspiral only templates for both detection and parameter estimation of the full coalescence waveforms generated by numerical relativity simulations. To this end, we deploy as search templates waveforms based on the effective one-body waveforms terminated at the light-ring as well as standard post-Newtonian waveforms. We find that both of these are good for detection of signals. Parameter estimation is good at low masses, but degrades as the mass of the binary system increases.

متن کاملMeasuring gravitational waves from binary black hole coalescences. I. Signal to noise for inspiral, merger, and ringdown
We estimate the expected signal-to-noise ratios ~SNRs! from the three phases ~inspiral, merger, and ringdown! of coalescing binary black holes ~BBHs! for initial and advanced ground-based interferometers ~LIGOVIRGO! and for the space-based interferometer LISA. Ground-based interferometers can do moderate SNR ~a few tens!, moderate accuracy studies of BBH coalescences in the mass range of a few ...
متن کاملGravitational-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 کاملTransition from inspiral to plunge in binary black hole coalescences
Combining recent techniques giving non-perturbative re-summed estimates of the damping and conservative parts of the two-body dynamics, we describe the transition between the adiabatic phase and the plunge, in coalescing binary black holes with comparable masses moving on quasi-circular orbits. We give initial dynamical data for numerical relativity investigations, with a fraction of an orbit l...
