    Abstract

    Following the first direct detection of gravitational waves by LIGO, the next breakthrough could be joint observations with electromagnetic emissions. This thesis presents the scientific motivation and development of a new low-latency binary merger gravitational wave detect ion pipeline to help facilitate capture of prompt electromagnetic emissions. This new development includes the exploration of coherent information from different detectors, a novel significance evaluation method for gravitational wave signals, and computational acceleration using Graphics Processing Units. This thesis reports on the pipeline performance using realistic data, and also reports on a preliminary online search result during the first Advanced LIGO science run.
