A Study of the Evolution of Large Scale Structures Based on the Ultra Wide Band Mm/Submm Observations

我们利用安装在亚毫米波望远镜ASTE上的连续照相机，发现了1400多个被尘埃遮蔽的大质量星暴星系（亚毫米波星系）。为了研究它们的红移和性质，我们研制了多波段超导相机和超宽带光谱系统。我们发现了一个与早期宇宙大尺度结构相关的亚毫米星系群（红移为3.1）。我们还发现了被引力透镜放大的超亮亚毫米星系和非常高z的亚毫米候选星系。包括这些，我们获得了关于大质量星系形成和演化的重要线索。

We uncovered more than 1400 dust-obscured massive starburst galaxies (submm-galaxies) using a continuum camera mounted on the submm-wave telescope ASTE. In order to study their redshifts and properties, we developed a multi-band super-conducting camera and an ultra wide-band spectroscopy system. We discovered a cluster of submm-galaxies associated with the large-scale structure in the early universe (at a redshift of 3.1). We also found ultra-bright submm-galaxies amplified by a gravitational lens and very high-z sub-mm galaxy candidates. Including these, we obtained important clues on the formation and evolution of massive galaxies.
