| Outline of Annual Research Achievements |
During the 2018 fiscal year, the final objective of this project was achieved. The GstLAL gravitational‐wave signal detection system was generalized to include support for the KAGRA detector. This required the development of a novel approximation scheme for assessing the consistency of a potential gravitational-wave signal observed by multiple detectors, by comparing the amplitude, arrival time, and phase with which the signal is observed by each of the detectors in the network. This work is described in the paper arXiv:1901:02227, which is currently undergoing peer review. During the 2018 fiscal year, the technique described in that paper was implemented in the GstLAL gravitational-wave detection software system and the new system was deployed for Advanced LIGO and Advanced Virgo's third observation run, "O3". It is anticipated that Japan's KAGRA detector located in the Kamioka Mountain will join the O3 observation run later this fiscal year, and when it does, thanks to the work supported by this project, the GstLAL detection system will be ready to process its data and discover new gravitational‐wave signals with KAGRA.
