\n\u3010Abstract\u3011
\nGalaxy clusters play an important role for the large-scale structure of the universe and galaxy evolution. Galaxy clusters are located in the densest peaks of dark matter, and galaxies lying inside galaxy clusters are generally more massive and older than those in low-density regions.
\nWhen and how were these distinct properties formed? One promising line of study is to investigate directly the primitive galaxy clusters, “protoclusters”, in the early universe. Especially, we focus on the start of cluster formation. However, only a few high-z protoclusters were found. Therefore, we are searching for new high-z protoclusters in the deep and wide field of Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) Deep fields, and found two protocluster candidates at z~6.

\n\u3010Abstract\u3011
\nIt is widely accepted that molecular gas is the dominant material of star formation.
\nSince H2 (molecular hydrogen) is not observable, the second abundant molecular 12CO has become a proxy of tracing molecular gas. However, 12CO is optically thick, which is able to trace the molecular gas at the surface of molecular cloud only.
\nTherefore the observation in optically thin line, such as 13CO is needed. We observe both 12CO and 13CO toward NGC 628 to constrain the ability of a optically thin line in determining the molecular gas properties and its relation with star formation. Both observation and data analysis are ongoing.<\/p>\n","protected":false},"excerpt":{"rendered":"
