Outline of Final Research Achievements

Fast Radio Burst (FRB) is a mysterious radio-astronomical phenomenon in which a radio pulse of about ~1 millisecond is observed at GHz band. We have developed a backend system for FRB observations as well as software for its data analysis and have carried out FRB observations using radio telescopes in Japan. Observations were conducted mainly on three repeating FRBs, and one of them, FRB 20201124A (repeating FRB at z = 0.098), has been successfully detected. This is the first FRB detection by a radio telescope in Japan. In addition, the detected burst exhibited substantial difference from the previous suggestion, in which non-repeating FRBs are significantly brighter than repeating FRBs and thus they are different populations. Our FRB detection emphasizes the importance of further follow-up observations for revealing the nature of FRBs.

Academic Significance and Societal Importance of the Research Achievements

Fast Radio Burst(FRB)と呼ばれる正体不明の電波バースト現象の観測研究のため、国内の電波望遠鏡でその信号を検出するシステムと解析ソフトを開発した。それに基づいて3天体の再帰型FRBの観測を行ったところ、1天体で電波バーストを検出することに成功した。これは、日本の電波望遠鏡を用いたものとして初めての検出であり、日本のおけるFRBの観測研究の幕開けとなるマイルストーンとなった。
