Ito Hall, the University of Tokyo), Bunkyou-ku, Tokyo, Japan, We explore the possibility of studying redshifted far-IR fine-structure transitions through cosmic time using 3- dimensional power spectra obtained with an imaging spectrometer. The intensity mapping approach measures the spatio-spectral fluctuations due to line emission from all galaxies, including those well below the individual detection threshold. With assumptions about large-scale structure, the large-scale fluctuations measure the total volume emissivity in a given transition, with redshift information naturally encoded. We consider as specific examples the possibility of studying redshifted [O I] 63 μm and [Si II] 35 μm with the SAFARI instrument aboard SPICA. While envisioned SAFARI surveys will only detect the brightest galaxies individually, the fluctuation signal from the aggregate population is detected with high significance: cumulative SNR of order 100 for both the total and shot noise power spectra, and order 10 for the clustering power spectrum from surveys sketched in this proceedings article., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027030, レポート番号: JAXA-SP-17-010E}, pages = {133--135}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Intensity Mapping of Fine Structure Line Emission as a Probe of Large Scale Structure and the Evolving ISM in Dusty, Star-Forming Galaxies at Moderate Redshift}, volume = {JAXA-SP-17-010E}, year = {2018} }
