Research Abstract

We made computer servers for computer simulation to make gravitational wave templates and carried out performance tests. As for data analysis, an efficient structure of template bank is given. In addition, we revealed that the analysis using the Hilbert-Huang transformation is effective for burst sources, to which it is hard to apply the matched filter method simply.
