Argentine Institute of Radio Astronomy

The Argentine Institute of Radio Astronomy (Spanish: Instituto Argentino de Radioastronomía, IAR) was jointly established by the National Scientific and Technical Research Council, the National University of La Plata and the University of Buenos Aires. Its functions are to promote and coordinate research and technical development of radio astronomy and collaborate in teaching.

In the year 1963, construction began on the first 30 m telescope under the direction of Carlos Varsavsky. The observatory entered service on March 26, 1966.

The IAR participates in the Long Latin American Millimeter Array, and will join the Cherenkov Telescope Array project, using a site either near San Antonio de los Cobres or at the Leoncito Astronomical Complex.
