Toward Early-Warning Detection of Gravitational Waves from Compact Binary Coalescence

TL;DR

This paper proposes a practical filtering strategy for early-warning detection of gravitational waves from compact binary coalescence, enabling alerts before the final merger occurs, thus facilitating multi-messenger astronomy.

Contribution

It introduces a novel, computationally efficient method for early detection of gravitational waves prior to the merger event.

Findings

The filtering strategy can produce early-warning triggers.

The method is computationally practical for real-time detection.

It enhances the potential for multi-messenger observations.

Abstract

Rapid detection of compact binary coalescence (CBC) with a network of advanced gravitational-wave detectors will offer a unique opportunity for multi-messenger astronomy. Prompt detection alerts for the astronomical community might make it possible to observe the onset of electromagnetic emission from (CBC). We demonstrate a computationally practical filtering strategy that could produce early-warning triggers before gravitational radiation from the final merger has arrived at the detectors.
