Developments in Sub/Millimeter Astronomy in Chile Mónica Rubio Universidad de Chile Llama Workshop, FAPESP, 9 aug 2011
The start 1.2 m Columbia radio telescope @ CTIO in 1984 Collaboration between Columbia University and UCH 1984 115 GHz CO surveys of the Southern Milky Way and Magellanic Clouds. 15 m SEST Telescope @ La Silla 1987-2003 - 5 Faculty, Radio astronomy group at the Astronomy Department, UCH
Today Seven universities with astronomy departments/groups At least one radio-astronomer in each of the new institutions Graduate students performing PhD and Master s thesis in submillimeter astronomy
