AKARI Deep Field South(ADFS)におけるサブミリ波銀河の解析

Galaxies with large amounts of dust, bright at submillimeter wavelengths, and explosive star formation in the early universe are called "submillimeter-wave galaxies. What is the importance of observing these galaxies? First of all, the rate of star formation, which is not observable in visible or infrared light, increases rapidly as we move back in time. In other words, to obtain a complete picture of star formation activity in the universe, it is essential to search for star-forming galaxies in the early universe and study their number and brightness to determine how they have changed over the course of history.Analysis of the ADFS(AKARI Deep Field South) data detected several spectra that could be considered CO emission lines.
