The Einstein Telescope (ET) research infrastructure is envisioned as Europe’s first next-generation underground observatory for gravitational-wave detection. Its engineering design requires a multi-criteria approach capable of identifying and addressing geological, geotechnical, environmental, and landscape challenges. To manage this complexity, a Design Digital Twin (DDT) framework is being...

The geological characterization of the Italian candidate site for the Einstein Telescope (ET) in Sardinia relies on integrating heterogeneous datasets to support the engineering design and geomechanical characterization of the observatory. A 3D geological model, derived from industrial data and primary structural constraints, is already available and serves as the deterministic baseline for...

Newtonian noise is expected to limit the low-frequency sensitivity of the Einstein Telescope, particularly in the 3-15 Hz band. Most existing estimates rely on analytical or semi-analytical models assuming homogeneous or layered media, neglecting geological heterogeneity and complex wave interactions. In this work, we present a numerical framework for Newtonian-noise estimation based on...

The Einstein Telescope (ET), a next-generation underground gravitational-wave observatory planned in Sardinia (Italy), requires detailed subsurface characterization to ensure structural stability and minimal environmental noise. Understanding the distribution of fractured zones and groundwater systems within the crystalline basement is critical, as these factors directly affect excavation...

Public communication and stakeholder engagement are essential components of the site characterization activities for the Einstein Telescope (ET), particularly when operations involve visible and potentially sensitive airborne geophysical surveys over inhabited territories. Within the framework of the ET geological and environmental investigations in Sardinia, dedicated communication actions...

Accurate prediction of seismic noise and Newtonian noise is essential for characterizing candidate sites for the Einstein Telescope (ET), a third-generation underground gravitational-wave observatory. Near-surface settings with a low-velocity sedimentary layer overlying hard rock can strongly modify the seismic wavefield and, consequently, the associated Newtonian noise. In this study, we...

The Einstein Telescope (ET) is a next-generation underground gravitational wave observatory planned to operate at depths of up to 200–300 m, where seismic, thermal and Newtonian noise are significantly reduced compared to surface detectors. ET requires a geologically stable, well-characterised host rock over an exceptionally large volume 100-225 km². The Lusatia (Lausitz) region in eastern...

Seismic disturbances, and the resulting Newtonian noise, can arise from a variety of sources with either stationary or non-stationary characteristics. In this work, we focus on two representative transient source types: wind turbines and freight trains. As part of the integrated seismic noise monitoring and mitigation campaign at the EMR candidate site for the Einstein Telescope, surface and...

We investigate the seasonal variability of atmospheric infrasound and its impact on Newtonian noise (NN) at the Sos Enattos site, a candidate location for the Einstein Telescope. Measurements from surface and underground stations are used to characterize both temporal changes and the depth dependence of the acoustic field. Clear seasonal variations are observed, primarily driven by changing...

Sos Enattos in Sardinia (Italy) is a leading candidate site for the Einstein Telescope (ET), a next-generation underground gravitational wave observatory. We report recent results from an environmental magnetic noise study, with the aim of quantifying natural noise sources in the low-frequency band relevant to the ET-LF interferometer. Using a network of magnetometers deployed at Sos Enattos...

"In the framework of the costitution of the Sardinia FABER Far Field Observatory funded by PNRR project MEET, a new magnetic and magnetotelluric monitoring station has recently been installed in the Mamone area. This is also a key element for the site characterization program for the Einstein Telescope (ET), to investigate the electromagnetic properties and natural magnetic noise conditions of...

Abstract:
The Einstein Telescope gravitational wave observatory aims to achieve a sensitivity down to 3 Hz, where Newtonian noise becomes a dominant disturbance. Seismic waves propagating in the surrounding soil generate density fluctuations that induce gravitational forces on the suspended mirrors. Since these forces cannot be shielded, they must be estimated from the seismic wave field...

Several geophysical survey campaigns were conducted to investigate the subsurface in order to map and characterize potential stratigraphic boundaries and fault zones. These primarily included seismic surveys, but also surveys using electrical resistivity tomography. The primary focus here is on the near-surface area. In this presentation, we would like to introduce these methods and...

The characterization of the sites candidate to host ET pass through the evaluation of the local noise source (both natural and anthropogenic). The time analysis of the RMS quantity, computed over a specific frequency range, can be used to evaluate the short-term non-stationarities and the noise level at the site as a function of time. Moreover, consecutive periods of low noise level, once...

Microseisms are continuous ground vibrations excited by ocean-wave activity, typically around 0.1 Hz with amplitudes of the order of micrometers. Although they lie below the observation band of ground-based gravitational-wave detectors, they can still have important impacts on detector operation and site characterization. In LIGO and Virgo, microseisms can couple to the detector through...

Geophysical investigations and studies on the local seismic noise are of paramount importance for evaluating the candidate locations for hosting Einstein Telescope (ET), the third-generation gravitational wave detector. In the Italian candidate site, several active and passive geophysical acquisitions have been carried out over the last years. The main objective of the recent analysis is the...

Accurately predicting seismic Newtonian Noise (NN) for the Einstein Telescope remains a significant challenge. To determine whether a site-specific NN level is compatible with the target sensitivity of the Einstein Telescope (ET), it is essential to have a solid understanding of NN estimation and its planned mitigation. Validating numerical NN estimates requires careful consideration of three...

The sensitivity of future ET observation runs is influenced by site-dependent local noise conditions. Within the Noise Measurements Division (WD1) of the Site Characterization Board (SCB), prominent noise types are measured and characterized to provide a robust understanding of the background noise at the site candidates. Measured noise includes, but is not restricted to, 1) seismic, 2)...
