Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, We study the origin of the [O I] 63, [N II] 122, [O I] 145, and [C II] 158 line deficits in z less than 0.3 Ultraluminous Infrared Galaxies, using data from Herschel. The line deficits are consistent with arising from increased quantities of dust in HII regions, but part of the [C II] deficit may arise from an additional mechanism, plausibly increased grain charging. We briefly discuss some implications from these results for SPICA., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027025, レポート番号: JAXA-SP-17-010E}, pages = {113--115}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Far-Infrared Line Deficits in Ultraluminous Infrared Galaxies}, volume = {JAXA-SP-17-010E}, year = {2018} }
