研究実績の概要

The following objectives were achieved:
1. Prepared the GstLAL analysis software suite for the data to be collected from the Japanese KAGRA gravitational wave detection in April of 2020. 2. Continued development of an analytic model of the sensitivity of the GstLAL gravitational-wave detection system to signals, working towards removing the need to measure sensitivity with large brute force numerical simulations. 3. Continued developing the first system capable of cleaning a class of gravitational-wave signals from detector data for the purpose of constructing a signal-free data set for traning machine learning signal identification classifiers. 4. Continued developing a high-speed gravitational-wave source direction finding system suitable for use with a GstLAL-based earling warning system for gravitational waves from compact object mergers.

In addition, during the 2019 fiscal year Canon gave 6 invited lectures in 3 countries including Japan. Two of those were summer school style training sessions for young researchers. Cannon published 15 peer reviewed papers presenting the results of LIGO and Virgo O1 and O2 data.

2: おおむね順調に進展している

理由

Although the progress throughout the fiscal year was excellent, in March of 2020 the spread of the pandemic caused the cancellation of a major conference that our group was planning to attend. This necessitated a substantial, unexpected, carry-over.

今後の研究の推進方策

1. In April of 2020 the Japanese KAGRA gravitational-wave telescope will collect its first observational data. It will not be sensitive enough to see astrophysical gravitational waves unless an extraordinarily loud signal arrives, but our group will use the GstLAL detection system currently in use for LIGO and Virgo data analysis to process the KAGRA data in a demonstration of end-to-end data collection and analysis for this new Japanese gravitational wave telescope. 2. We anticipate transitioning several of our group's on-going projects from developmental, experimental, tools into production quality software for deployment use in future LIGO/Virgo/KAGRA observing runs, including: the analytic detector sensitivity estimation project, the GstLAL data rate reduction project, and the gravitational-wave source direction identification tool.
