Radio and Geoastronomy: Facilities
SMA telescope The Submillimeter Array
The Submillimeter Array (SMA) is the world's first imaging interferometric telescope to operate in the major atmospheric windows from 0.3mm to 1.3mm. Located at the summit of Mauna Kea 13,386 feet above sea level, the array consists of eight 6-m movable antennas that can be positioned in different locations to provide highest angular resolution equivalent to an antenna of 0.5 km (0.3 miles) across. The SMA explores a range of astrophysical phenomena including solar system bodies, young and evolved stars, galaxies, and active galactic nuclei.
Mini telescope The 1.2 Meter Millimeter-Wave Telescope
For over three decades the CfA 1.2 meter telescope and its twin instrument in Chile have been mainly dedicated to obtaining what is by far the most extensive, uniform, and widely-used survey of dense, star-forming molecular clouds in our Galaxy. A total of 24 PhD dissertations have so far been written based on observations or instrumental work with these telescopes, and many more undergraduate students have participated in the observations either in course laboratories or as observing assistants.
