| Outline of Annual Research Achievements |
1. In 2020 the Japanese KAGRA gravitational-wave telescope collected its first observational data. Members of our group used the GstLAL detection system we previously developed for LIGO and Virgo data analysis to process the KAGRA data, and demonstrated the successful end-to-end operation of the KAGRA telescope from data collection through to search result. 2. We transitioned one of our group's resarch projects, the analytic detector sensitivity estimation project, from development into production quality software for deployment use in future LIGO/Virgo/KAGRA observing runs. 3. Other projects including the GstLAL data rate reduction project, and the gravitational-wave source direction identification tool are nearing completion. 4. We have successfully hired a postdoctoral researcher.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Boarder closures, university campus closures, the cancellation of conferences, have all made work that relies on collaboration among groups of researchers difficult. Progress has not been as quick as we had hoped, nevertheless forward progress has been made. A postdoc hire that was part of the original research plan was successful, and we are look forward to completing a number of our group's on-going research projects in time for the start of the LIGO/Virgo/KAGRA O4 observing run in December 2022.

| Strategy for Future Research Activity |
During the coming fiscal year, our group will: 1. Complete the integration of our high-speed source localization software into the GstLAL online compact object collision detection system for use in LIGO/Virgo/KAGRA's O4 observing run. 2. Complete and publish a search for Cherenkov-like gravitational-wave bursts. 3. Publish an analysis of the ability of gravitational-wave observations to constrain a new model of neutron star interiors. 4. Complete the integration of our data rate reduction technique into the GstLAL system.
