 note = {SPICA Science Conference from Exoplanets to Distant Galaxies: SPICA's New Window on the Cool Universe (June 18-21, 2013. Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, We have investigated the dependence of galaxy properties on their surrounding environments with AKARI/IRC. We found less star-forming galaxies tend to be in dense region at z = 0.8 whereas at z greater than 0.8 universe, the star formation are more active in denser region, consistent with the previous work. As an indicator of star formation, we used 8 μm to 4.5 μm flux ratio, which is reduced by the radiation from Active Galactic Nuclei so that it can trace pure star forming galaxies. Such a useful indicator could be used by only AKARI which has a continuous wavelength coverage between 2-24 μm. In future work we suggest to extend this work to z = 3.5 universe using SPICA which has also continuous wavelength coverage at mid-infrared and has a great spatial resolution, which is needed to avoid source blend in dense regions., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027032, レポート番号: JAXA-SP-17-010E},
