Recent deliverables from RockSoil S.p.A. have significantly advanced our geological and hydrogeological understanding of the Sos Enattos area, which is being considered as a potential location for the Einstein Telescope (ET). The dataset includes results from eleven deep boreholes, geophysical surveys (ERT and SRT) and magnetometry and radon gas measurements. These results have been integrated...
Comprehensive hydrogeological and groundwater modelling studies are underway to assess feasibility of the construction of the Einstein Telescope (ET) facility in the Euregion Meuse-Rhine (EMR) region. The facility includes ~30 km tunnels with 10 m of width arranged in a triangular shape, and shafts and cavern structures in the corners. The construction and operation of this facility will...
The Einstein Telescope (ET) research infrastructure is set to become the pioneering next-generation underground observatory for gravitational wave detection.
ET engineering design demands a multi-criteria approach to identify and address geological, geotechnical, environmental, and landscape challenges. To address these complexities, a Design Digital Twin (DDT) is being developed as a...
The Sos Enattos site in Sardinia remains a key location for multidisciplinary research activities in support of the development of the Einstein Telescope (ET), a next-generation gravitational wave observatory. Current efforts include deploying advanced seismic, magnetic and environmental sensor arrays at various depths to enable long-term monitoring of site stability and noise levels....
The characterization of local seismic noise is of paramount importance for evaluating candidate locations for hosting the Einstein Telescope (ET), the third-generation gravitational wave detector. Three temporary seismic arrays were installed at the Italian candidate site for ET, each with different geometrical layouts, recording durations, and total numbers of stations. Here, we provide an...
Third-generation terrestrial gravitational-wave detectors, such as the Einstein Telescope and Cosmic Explorer, would offer significantly greater sensitivity and a wider frequency range than existing detectors. Third-generation detectors are designed to be able to detect gravitational waves below 10 Hz. In this frequency range, seismic noise and gravitational gradient noise (also known as...
The detection of gravitational waves with large-scale laser interferometers such as LIGO and VIRGO has opened a new era in physics, and the scientific community is now planning to build the Einstein Telescope (ET), a next-generation detector with significantly higher sensitivity. These instruments are highly sensitive to seismic noise from natural and anthropogenic sources. In particular, the...
The Sos Enattos area in Sardinia, Italy, is one of the most promising locations for the Einstein Telescope (ET), a next-generation underground gravitational wave observatory. In this study, we present the results of a recent environmental magnetic noise analysis aimed at characterising natural noise sources in the low-frequency band. Using a network of sensors deployed in the region, we...
Distributed Acoustic Sensing (DAS) turns standard telecommunication fibers into dense seismic arrays with thousands of measurement points. Within the WAVE initiative, a 16 km fiber provides more than 16,000 virtual seismic channels in collaboration with DESY on the Bahrenfeld research campus in Hamburg. The project investigates how such large-scale DAS networks can advance environmental...
I present the analysis of the infrasound measurements at the Sos Enattos mine. I discuss the correlations between different stations. Additionally I present the level of the infrasound induced newtonian noise and discuss the ways to mitigate its influence on the detector.
