Outline of Final Research Achievements

Studying the chemical evolution of galaxies is crucial to understand the evolutionary history of the current metal-rich Universe. However it has been difficult to diagnose the physical and chemical properties of young galaxies observationally, since actively star-forming young galaxies tend to be enshrouded by heavy dust. We carried out systematic surveys for young dusty galaxies by utilizing brand-new instruments such as Subaru Hyper Suprime Cam, and found that such galaxies tend to possess an active supermassive black hole in their nucleus in a growing-up phase. Our sub-millimetric spectroscopy with ALMA revealed that the chemical evolution of galaxies had occurred in a very short timescale in the early Universe.
