The Virgo Experiment

virgoGravitational waves are ripples in the curvature of spacetime predicted by the General Relativity theory from Albert Einstein. The Virgo Michelson interferometer has been built to detect and characterize these waves. Between 2007 and 2011 Virgo collected data in coincidence with the American detectors of LIGO. In 2015, gravitational waves were detected for the first time. Since 2017, the detector of second generation, Advanced Virgo has been taking data in coincidence with the LIGO advanced detectors and participated to new detections.

The Group’s Activities

The Virgo-LAL group is involved in many activities:

  • The searches for bursts of gravitational-wave signals in LIGO-Virgo data
  • The multi-messenger astronomy
  • The Virgo detector characterization
  • The development of vacuum-control hard/software elements
  • The study of new lock acquisition methods for the detector operation (CALVA)
  • The development of R&D solutions for future gravitational-wave detectors (CALVA)
