Infrared Astronomy in Antarctica
In Antarctica the cold and dry air is expected to provide the best observing conditions on the Earth for astronomical observations from infra-red to sub-millimeter. To enjoy the advantages in Antarctica, we have a plan to make astronomical observations at Dome Fuji, which is located at inland Antarctica. However, the harsh environment is very problematic. For example, the temperature comes down to as low as -80 degree Celsius in winter, where instruments designed for temperate environment would not work. In this context, we have developed a 40 cm infra-red telescope, which is dedicated for the use even in winter at Dome Fuji. We are now planning the construction of 2m-class infrared telescope.
[current project (2)]
The superb image quality of Subaru telescope and excellent atmospheric condition at Mauna Kea in Hawaii, especially in near-infrared, enable us to observe fine structures of faint objects. To enjoy the advantages of Subaru telescope and the development of large focal plane arrays in near-infrared, we have constructed Multi-Object InfraRed Camera and Spectrograph (MOIRCS), which is a facility instrument dedicated for wide-field imaging and multi-object spectroscopy in near-infrared. The designing was started in 1999 jointly by Subaru Telescope of National Astronomical Observatory Japan and Institute of Astronomy, Tohoku University. MOIRCS saw the first light in September, 2004. It is now operated as a common use instrument open for all astronomers in the world.
