The Australian International Gravitational Observatory (AIGO) is a research facility located near Gingin, north of Perth in Western Australia. It is part of a worldwide effort to directly detect gravitational waves (N.B. these are different from gravity waves).
It is operated by the Australian International Gravitational Research Centre (AIGRC) through the University of Western Australia under the auspices of the Australian Consortium for Interferometric Gravitational Astronomy (ACIGA).
The current aim of the facility is to develop advanced techniques for improving the sensitivity of interferometric gravitational wave detectors such as LIGO and VIRGO. A study of operational interferometric gravitational wave detectors shows that AIGO is situated in almost the ideal location to complement existing detectors in the Northern hemisphere.
