Outline of Final Research Achievements

In order to investigate the co-evolution of galaxies and active galactic nuclei (AGN), we have built an integral-field unit (IFU) for MOIRCS, near-infrared spectrograph for SUBARU telescope. We have also analyzed spectral energy distributions (SEDs) of galaxies found in the north ecliptic pole field to select targets for integral-field spectroscopy. Cooling tests of the IFU were made using the focal plane box of MOIRCS and we confirmed the stability of the optics. The SED analysis in this study enables us to select heavily obscured Compton-thick AGN candidates.
