Transient non-gaussian noise in gravitational wave detectors, commonlyreferred to as glitches, pose challenges for inference of the astrophysicalproperties of detected signals when the two are coincident in time. Currentanalyses aim towards modeling and subtracting the glitches from the data usinga flexible, morphology-independent model in terms of sine-gaussian waveletsbefore the signal source properties are inferred using templates for thecompact binary signal. We present a new analysis of gravitational wave datathat contain both a signal and glitches by simultaneously modeling the compactbinary signal in terms of templates and the instrumental glitches usingsine-gaussian wavelets. The model for the glitches is generic and can thus beapplied to a wide range of glitch morphologies without any special tuning. Thesimultaneous modeling of the astrophysical signal with templates allows us toefficiently separate the signal from the glitches, as we demonstrate usingsimulated signals injected around real O2 glitches in the two LIGO detectors.We show that our new proposed analysis can separate overlapping glitches andsignals, estimate the compact binary parameters, and provide ready-to-useglitch-subtracted data for downstream inference analyses.
