Refining Methods for Placing Upper Limits on Glints in LIGO Data from the First Three Observing Runs

Gravitational waves are ripples in the fabric of spacetime that contract and expand distances when they pass through space. The LIGO-Virgo-Kagra collaboration (LVK) which operates detectors throughout the United States, Europe and Japan, have detected over two hundred of these events over the last ten years. General relativity predicts that these waves should scatter off of dense perturbers and produce "glints" that would manifest in detector data as smaller, time delayed copies of the original wave signals. We have investigated all gravitational wave events present throughout the data released from the first three LIGO observing runs with signal-to-noise ratios greater than 12.0. So far, we have not found any events where a model incorporating a glint has been favored over a standard gravitational wave model, and as such have developed methods for placing constraints upon glinted signals being present in the LVK data throughout these first three observing runs.
