Correlation between Gamma-Ray bursts and Gravitational Waves

TL;DR

This study searched for simultaneous signals between gamma-ray bursts and gravitational waves using AURIGA and BATSE data, setting an upper limit on gravitational wave amplitude associated with GRBs.

Contribution

First correlation search between GRBs and gravitational waves, establishing an upper limit on gravitational wave amplitude linked to GRBs.

Findings

No correlation detected between GRBs and gravitational waves.

Set an upper limit of $h_{RMS} \, \leq 1.5 \times 10^{-18}$ on gravitational wave amplitude.

Provided the first constraint on gravitational waves associated with GRBs.

Abstract

The cosmological origin of $\gamma$-ray bursts (GRBs) is now commonly accepted and, according to several models for the central engine, GRB sources should also emit at the same time gravitational waves bursts (GWBs). We have performed two correlation searches between the data of the resonant gravitational wave detector AURIGA and GRB arrival times collected in the BATSE 4B catalog. No correlation was found and an upper limit \bbox{$h_{\text{RMS}} \leq 1.5 \times 10^{-18}$} on the averaged amplitude of gravitational waves associated with $\gamma$-ray bursts has been set for the first time.
