AURIGA (Antenna Ultracriogenica Risonante per l'Indagine Gravitazionale Astronomica) is an ultracryogenic resonant bar gravitational wave detector in Italy.{{cite web|url=https://arstechnica.com/science/2012/12/threatening-to-discover-quantum-gravity-with-a-big-metal-bar/|title=Threatening (to discover) quantum gravity with a big metal bar|first=Matthew|last=Francis|publisher=Ars Technica|date=2012-12-18}} It is at the Laboratori Nazionali di Legnaro of the Istituto Nazionale di Fisica Nucleare, near Padova.{{cite web|url=http://www.infn.it/esperimenti/esperimentien.php?gruppo=2&sigla_naz=AURIGA |title=AURIGA EXPERIMENT, RESPONSIBLE: Massimo Cerdonio |publisher=INFN |accessdate=2012-12-18 |url-status=dead |archiveurl=https://web.archive.org/web/20060510140409/http://www.infn.it/esperimenti/esperimentien.php?gruppo=2&sigla_naz=AURIGA |archivedate=2006-05-10 }} It is being used for research into gravitational waves and quantum gravity.

When the oscillator gets hit with a burst of gravitational waves, it will excite the oscillator and it will vibrate for a time span longer than the duration of the gravitational wave burst. This allows for the extraction of the signal from the detector.
