Atacama Submillimeter Telescope Experiment (ASTE)

The ASTE project and current status

The Atacama Submillimeter Telescope Experiment (ASTE) is a project to operate a high precision 10 m submillimeter telescope at a high altitude site (4860 m) at Atacama desert in Northern Chile. The major goals of the project are (1) to explore the southern sky with submillimeter waves up to 900 GHz, and (2) development and on-site evaluation of observation techniques and methods for submillimeter observations. The project is driven by the National Astronomical Observatory of Japan (NAOJ) in collaboration with Universidad de Chile, and Japanese institutes including University of Tokyo, Nagoya University, Osaka-Prefecture University, Ibaragi University, and Hokkaido University. Following the extensive instrumental studies, ASTE has successfully started its normal astronomical observations at wavelenght of 0.87 mm (350 GHz) since 2004 and many Japanese and Chilean astronomers have made scientific observations using ASTE.
