 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, I propose to search for dust-free quasars without hot-dust emission at z greater than 6. I plan to perform the deep mid-infrared photometry with Mid-infrared Camera and Spectrometer (MCS). Its high sensitive and continuous-band (5-38 μm) imaging enables us to investigate the contribution not only of the hot dust component (rest frame: 1-3 μm) but also of the warm dust component (rest frame: greater than 3 μm) of quasars at z greater than 6. When the SPICA begins the observation, several hundreds of quasars at z greater than 6 are expected to be discovered by Hyper Suprime-Cam (HSC) which is a gigantic digital still camera for 8.2m Subaru telescope. For these z greater than 6 quasars, we examine the hot-dust abundance by utilizing the spectral energy distributions of rest-frame near-infrared regime. This study is expected to provide us the clue about the origin of the dust torus., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730027024, レポート番号: JAXA-SP-17-010E},
