Detecting a non-Gaussian stochastic background of gravitational radiation

TL;DR

This paper introduces a detection method for a non-Gaussian stochastic gravitational wave background, characterized by popcorn-like signals, based on the assumption that event durations are shorter than detector resolution.

Contribution

The paper develops a novel detection technique tailored for non-Gaussian gravitational wave backgrounds with popcorn-like signals, expanding beyond traditional Gaussian assumptions.

Findings

Derived a detection method for non-Gaussian gravitational wave backgrounds.

Applicable to signals where event intervals are much larger than durations.

Assumes event durations are shorter than detector time resolution.

Abstract

We derive a detection method for a stochastic background of gravitational waves produced by events where the ratio of the average time between events to the average duration of an event is large. Such a signal would sound something like popcorn popping. Our derivation is based on the somewhat unrealistic assumption that the duration of an event is smaller than the detector time resolution.
