銀河と銀河団の関係から探る銀河形成と進化

2021年，我发表了一篇论文，提交了3篇论文。我访问了西班牙安达卢西亚天文学研究所（CSIC），为期两个月，从事星系团相关函数和探测BAO的项目。我还访问了埃及国家天文学和地球物理研究所，为期两个月，从事BCG恒星质量-星团质量关系项目。在我访问埃及期间，我参加并组织了中东和非洲宇宙学学校的一个宇宙学学校，关于宇宙学的大星系调查。这些海上活动也是基于我在日本的东道主研究员的合作。

During 2021, I published one paper and submitted 3 papers. I had a visit to the Instituto de Astrofisica de Andalucia (CSIC), Spain, for two months working on the project of correlation function of galaxy clusters and detecting the BAO. I also had a visit to the National Research Institute of Astronomy and Geophysics, Egypt, for two months working on the project of the BCG stellar mass-cluster mass relation. During my visit to Egypt I participated and organized a cosmology school of the Middle-East and Africa School on Large Galaxy Surveys for Cosmology. Those activities over the sea are also based on the collaborations of my host researcher in Japan.
