ABSTRACT: Binary black holes are one of the most promising science targets for the advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), which is expected to be operational later in 2015. The detections made by aLIGO (or lack thereof) will provide stringent tests of Einstein's theory of General Relativity and our understanding of many astrophysical processes. It will be much easier to make a detection if aLIGO knows what to look for. We use numerical relativity simulations to accurately predict gravitational waveforms from binary black holes, but performing many simulations is computationally prohibitive. However, using reduced order modeling, we can make the most efficient use of numerical relativity and provide aLIGO with the predictions that are needed to maximize its scientific output.
