| Outline of Final Research Achievements |
The cosmic star-formation activity is known to have its peak around 2-3 billion years after the Big Bang. Orderly morphologies such as spirals and ellipticals then emerge. What is the primary driver of such evolution? In order to answer this fundamental question, we initiated the upgrade of MOIRCS, near-infrared instrument for Subaru Telescope. We also conducted intensive observations of distant and nearby galaxies. We obtained some critically important insights of galaxy evolution. We found the star-forming galaxies at z~2.5 with abundant molecular gas generated their stellar content rapidly, and terminated their activity around z~1.5. Then such galaxies evolved passively and became giant elliptical galaxies in the present universe.
