Research Abstract

We develop a new method for (sub)millimeter spectroscopy with a frequency-modulating local oscillator and implemented it on the ASTE submillimeter telescope in Chile. This improves observing efficiencies (×5) of single-dish spectroscopic observations, compared to conventional methods. Furthermore, we propose a new method for estimating redshifts of dust-enshrouded star-forming galaxies and reveal star-formation activities in high redshiftstarburst galaxies on the basis of submillimeter observations, spatial correlation with cosmic large-scale structures, and a lack in obscured star-formation in Lyman-alpha emitting galaxies, and so on.
