ArchEnemy: Removing scattered-light glitches from gravitational wave data

Understand

Data recorded by gravitational wave detectors includes many non-astrophysical transient noise bursts, the most common of which is caused by scattered-light within the detectors.

• These so-called ``glitches'' in the data impact the ability to both observe and characterize incoming gravitational wave signals.
• In this work we use a scattered-light glitch waveform model to identify and characterize scattered-light glitches in a representative stretch of gravitational wave data.
• We identify $2749$ scattered-light glitches in $5.96$ days of LIGO-Hanford data and $1306$ glitches in $5.93$ days of LIGO-Livingston data taken from the third LIGO-Virgo observing run.
