Research Abstract

We have carried out NIR wide-field imaging of the Subaru Deep Field (0.25 sq. degree) by the UKIRT/WFCAM instrument, and created a catalog of z~2 galaxies. Utilizing this catalog, we measured the clustering properties of z~2 star forming galaxies and found that these galaxies will evolve into present-day spiral galaxies. Deficiency of less-massive passive galaxies at z~2 is also found, suggesting the elliptical galaxies with stellar mass less than ~10^<11> solar mass are still under their formation phase. Following Subaru/MOIRCS NIR spectroscopy showed that the metallicity in these galaxies are as high as that in the present-day local galaxies, indicating that these galaxies have already experienced quite much amount of star-formation activities, and their inter-stellar gas has polluted by heavy elements.
