Gravitational waves from inspiraling compact binaries: Second post-Newtonian waveforms as search templates II

TL;DR

This paper demonstrates that second post-Newtonian waveforms are adequate for detecting gravitational waves from inspiraling compact binaries, validated through comparisons with black hole perturbation theory across various detector noise profiles.

Contribution

It provides evidence supporting the sufficiency of second post-Newtonian waveforms as search templates for gravitational wave detection from inspiraling binaries.

Findings

2-pN waveforms closely match perturbation theory signals

Validation across different detector noise curves

Supports use of 2-pN templates in gravitational wave searches

Abstract

We present further evidence that the second post-Newtonian (pN) approximation to the gravitational waves emitted by inspiraling compact binaries is sufficient for the detection of these systems. This is established by comparing the 2-pN wave forms to signals calculated from black hole perturbation theory. Results are presented for different detector noise curves. We also discuss the validity of this type of analysis.
