　　报告摘要：Cosmological simulations predict that galaxies preferentially form in the intersections of large-scale filaments, which are proto-clusters, in the early universe. Based on the galaxy surveys in the past few decades, we have known that local galaxies show distinctive properties in different environments, and cluster members are more likely red, passive, and elliptical than those in the field region. However, due to the survey depth/area limitation and the rareness of proto-clusters at high redshift, there were merely a few discussions on the connections between galaxies and large-scale environment at z>2. Thanks to the wide-field camera Hyper-Suprime Cam (HSC) installed on the 8.2-metre Subaru Telescope, a new era comes simultaneously with the sufficient survey area and imaging depths, making it possible to investigate large-scale structures at and beyond the Cosmic Noon in a statistical manner. This talk will review the topics of galaxy-IGM correlation, statistics of proto-cluster, and patchy reionization based on Subaru/HSC surveys, including MAMMOTH-Subaru, HSC-SSP, and so on.
