| Outline of Final Research Achievements |
The main purpose of this research is to shed new light on the histories of galaxy assembly by obtaining spatially-resolved mapping of star-formation activities within distant galaxies at redshift ~ 2, which corresponds to about 10 billion years ago. For this specific purpose, we developed new infrared narrow-band filters whose central wavelength are adjusted to include Hα emission lines from star-forming galaxies at redshift ~ 2 and conducted high-resolution imaging observation using the adaptive optics system and infrared imager onboard the Subaru telescope. We have successfully spatially-resolve the star-forming region and obtained the maps of the stellar age and star-forming activities within the galaxies at redshift ~ 2. Our preliminary results show that the star-formation is more active at the outer clump rather than the central region in the star-forming galaxy.
