Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, Absorption features due to interstellar ices are important probes of the interstellar environment. However ices in nearby galaxies have not been fully studied yet. With the AKARI near-infrared spectroscopy, we systematically observed 120 nearby galaxies, and detected H2O ice at 3.05 micrometers from 36 galaxies and CO2 ice at 4.27 micrometers from 9 galaxies. We find that ices are formed in the dust-rich and star-forming environment, and that CO2 ice may be efficiently formed due to massive star formation activities. With SPICA, we propose spectral mapping observations of ices for the AKARI sample galaxies. Based on the results, we will reveal spatial variations of the ice-forming interstellar environments within galaxies in detail., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027062, レポート番号: JAXA-SP-17-010E}, pages = {285--287}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Exploring the Ice-Forming Interstellar Environment in Nearby Galaxies with SPICA}, volume = {JAXA-SP-17-010E}, year = {2018} }
