| Outline of Final Research Achievements |
The galaxy formation is peaked at around 10 Billion years ago in the Universe, and thus it is the critical epoch for studies of galaxy formation and evolution. We make a series of narrow-band and medium-band filters on a new NIR camera SWIMS in order to conduct a large super multi-band imaging survey by capturing nebular emission lines from star forming galaxies and spectral break feature from older galaxies. This enables us to explore the histories of star formation and mass assembly and their environmental dependence. We have optimized the survey design based on the sensitivities of each filter. In preparation for the above mentioned large survey, we have conducted various observational projects with Subaru and ALMA telescopes targeting the galaxies in this critical peak epoch of their formation. These results are published in 26 papers in major refereed journals.
