E3: Geophysics and gravitational wave interferometric detectors
Gravitational waves are a prediction of Einstein’s theory of General Relativity. They are ripples in the space-time metric produced by cataclysmic astrophysical events. The direct detection of gravitational waves provides not only an important test of General Relativity, it also represent a new way to observe the Universe. The detection principle is based on the measurement of the space-time deformation between test masses with high-precision optical interferometers. The sensitivity of those instruments is limited at low frequency by seismic noise, due to geological and human activity. Geological activity affects the interferometric detectors, and conversely – for the same reason – the interferometric detectors can be used to extract information on the geological activity.
The goal of this project is to explore the possibility to use the data of the Virgo interferometer to extract useful geophysical information
