| Outline of Final Research Achievements |
This project had two main goals: (i) generalize the GstLAL gravitational-wave signal detection system (https://wiki.ligo.org/Computing/DASWG/GstLAL) so that it will be able to process data from the future Japanese KAGRA detector; (ii) search for gravitational waves from black hole and neutron star collisions in Advanced LIGO and Advanced Virgo's second observing run. Both goals were achieved. Notable among the accomplishments was the GstLAL detection system's discovery of GW170817, the first gravitational wave from a neutron star collision.

| Academic Significance and Societal Importance of the Research Achievements |
The discovery of GW170817 altered our understanding of the origin of heavy elements, and showed us that gravity moves at the speed of light, which had a significant impact on our understanding of the nature of gravity.
