Bayesian modelling of scattered light in the LIGO interferometers by Rhiannon Udall et al. on Tuesday 29 November

Excess noise from scattered light poses a persistent challenge in the

analysis of data from gravitational wave detectors such as LIGO. We integrate a

physically motivated model for the behavior of these "glitches" into a standard

Bayesian analysis pipeline used in gravitational wave science. This allows for

the inference of the free parameters in this model, and subtraction of these

models to produce glitch-free versions of the data. We show that this inference

is an effective discriminator of the presence of the features of these

glitches, even when those features may not be discernible in standard

visualizations of the data.
