| Research Abstract |
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.
