The Gist

Community science and machine learning are used to identify and classify glitches in LIGO data.

Explain Like I'm Five

"Imagine listening for tiny whispers, but sometimes there are loud pops that make it hard to hear. Scientists are using people like you and me to help find those pops in space data so they can hear the whispers better!"

Deep Intelligence Analysis

This paper describes the use of community science to identify new glitches in data from ground-based gravitational-wave detectors like LIGO. Glitches are short bursts of non-Gaussian noise that may hinder the ability to identify or analyze gravitational-wave signals. The Gravity Spy project studies glitches and their origins, combining insights from volunteers on the community-science Zooniverse platform with machine learning. The study examines volunteer proposals for new glitch classes, discussing links between these glitches and the state of the detectors, and examining how new glitch classes pose a challenge for machine-learning classification. The results demonstrate how Zooniverse empowers non-experts to make discoveries, and the importance of monitoring changes in data quality in the LIGO detectors. The identification and classification of glitches is crucial for improving the sensitivity and reliability of gravitational-wave detectors, enabling the detection of fainter and more distant gravitational-wave signals. The use of community science provides a valuable resource for identifying new types of glitches and understanding their origins.
