AURIGA (''Antenna Ultracriogenica Risonante per l'Indagine Gravitazionale Astronomica'') is an ultracryogenic resonant bar
gravitational wave detector in Italy. It is at the
Laboratori Nazionali di Legnaro of the
Istituto Nazionale di Fisica Nucleare, near
Padova.
It is being used for research into
gravitational waves and
quantum gravity
Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics; it deals with environments in which neither gravitational nor quantum effects can be ignored, such as in the vi ...
.
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.
