4年目(2022年度)は，秋以降に移動制限が徐々に解除され，国際会議などでの発表や対面での研究議論の機会がようやく復活するモードになった．日本の重力波干渉計KAGRAプロジェクトと，米欧LIGO-Virgoグループとは2023年5月より，第4期観測（O4）を開始することになり，研究代表の真貝は，観測開始時の重力波検出の判定を行う観測シフト体制のまとめ役となって，実観測時の対応や追観測する天文学者への情報公開手順などを取り仕切っている．研究分担者の伊藤は引き続き連続重力波解析のKAGRA側代表として，高橋も引き続き連携コンピューティングのKAGRA側代表として重力波データ解析の要職を務めている．2022年度は，LIGO-Virgo-KAGRAの共同観測チームとして，第3期観測（O3b）のデータ解析論文を共同執筆し，それらの毎週の議論の場に参加・査読の引き受け・一般向けの要旨（Science Summary）の作成などを精力的に行った．さらに，次期観測に向けての新たなデータ解析の手法の開発を進めた．Hilbert-Huang 変換を用いる重力波抽出法は論文投稿，自己回帰モデルを用いた重力波抽出は学会発表，独立成分解析を用いるノイズ除去などの新たな方法の実用化を進めている．また，アウトリーチについては，O4に向けての情報発信を中心に活動した．4年目に発表した研究成果は，論文発表18，学会発表15（うち国際学会6），一般向け講演・講義2，図書出版2 (単著1，事典項目1)，雑誌執筆1，雑誌編集協力3である．

In 2022, the mobile restrictions were lifted in the autumn, and opportunities for research and discussion on the development of international conferences were revived. Japan's gravity wave interference meter KAGRA, Mio LIGO-Virgo, May 2023, the beginning of the fourth phase of the survey (O4), research representatives, the beginning of the survey gravity wave detection and determination of the operation of the system, the time of the survey and the tracking of the information of astronomers open procedures. Research collaborator Ito Miki, representative of KAGRA side of gravity wave analysis, Takahashi Miki, representative of KAGRA side of gravity wave analysis. In 2022, LIGO-Virgo-KAGRA co-authored paper on gravity wave analysis of the third phase of measurement (O3b). The weekly discussion of the field to participate in the review of the introduction of the general direction of the main (Science Summary) and the preparation of the energy of the line. In addition, the development of new methods for the analysis of independent components in the next period of time is progressing.Hilbert-Huang transformation is used in the gravity wave extraction method. In 2004, the Center for Information Communication and Communication conducted research activities, including paper publication 18, society publication 15 (International Society 6), general lecture 2, book publication 2 (book 1, event book 1), journal writing 1, journal compilation collaboration 3.
