Argentine Institute of Radio Astronomy, Astronomical observatory in Berazategui Partido, Argentina.

The Argentine Institute of Radio Astronomy is a research facility operating two large radio telescopes that capture and analyze signals from space. The equipment functions on specific frequencies that allow scientists to examine distant cosmic objects.

The facility was established in 1962 to develop radio astronomy in South America and was from the start a collaborative project among multiple universities and research organizations. This partnership made it an important scientific center in the region.

The institute's name changed from National Institute of Radio Astronomy to Argentine Institute of Radio Astronomy after its founding. Its PuMA collaboration, run with the Rochester Institute of Technology, monitors millisecond pulsars daily and works with NANOGrav on the search for gravitational waves.

The institute sits in Pereyra Iraola Park, about 20 km from La Plata and within Berazategui Partido. The two 30-metre dishes stand beside laboratories, workshops, control rooms and offices. Access is by road through the park; check visiting arrangements with the institute beforehand, as this is a working research site.

The institute's Technology Transfer Area, created in the early 2000s, applies instrumentation know-how from radio astronomy to communication and space science. Its PuMA collaboration, run with the Rochester Institute of Technology, monitors millisecond pulsars daily and works with NANOGrav to help detect gravitational waves.
