| Outline of Final Research Achievements |
The Institute of Astronomy, the University of Tokyo is proceeding with the construction of the TAO 6.5-m telescope, the highest ground-based telescope at an altitude of 5640m on the summit of Cerro Chajnantor at Atacama in northern Chile. This observation site has a very dry climate, and the amount of water vapor that absorbs infrared rays from outer space is small in the atmosphere, making it suitable for observing infrared rays emitted by celestial bodies. It is the most excellent observation site on the ground for measuring substances related to water.
For the purpose of the observation of hydrated minerals and water ice on asteroids and comets, therefore, in this study, we developed near-infrared spectroscopic function on the Mid-Infrared Multi-field Imager for gaZing at the UnKnown Universe (MIMIZUKU) mounted on TAO telescope.
