Limburg, a region located in the cross-border area between The Netherlands, Belgium, and Germany is the Euregio-Meuse-Rhine candidate site for hosting the Einstein Telescope. Recent studies to investigate the site’s subsurface suitability for hosting Einstein Telescope has seen several boreholes being drilled and deployment of arrays of geophones on the surface. In this study we present a 3D...
The work carried out in in the candidate site for the Einstein Telescope in the EMR to characterise the functioning of deep groundwater, and its quality will be presented. Particular attention will be paid to new piezometric measurement campaigns, the interpretation of hydraulic tests in boreholes and groundwater sampling campaigns. First data and interpretation will be presented. Future works...
The Einstein Telescope (ET) will be Europe's next-generation underground interferometric gravitational wave detector. The extreme target sensitivity that these detectors should attain requires underground placement to shield the apparatuses from the ambient noise. A quiet environment in a geologically stable area away from major faults and industrial activities also helps to maximise the duty...
The Einstein Telescope (ET) is a proposed next-generation underground gravitational-wave detector in Europe, anticipated to enhance sensitivity by an order of magnitude compared to existing detectors while extending the observation band down to frequencies as low as 2 Hz. A thorough site characterization is critical for ET, considering geological, hydrogeological, and geotechnical conditions....
A designated area near the Sos Enattos mine (Lula, Nuoro Province, Sardinia, Italy) has been proposed as a candidate site for the Einstein Telescope (ET), a next-generation gravitational wave observatory requiring an exceptionally low-noise environment. To assess infrasound conditions relevant to ET, a set of infrasound microphones was installed at Sos Enattos, both on the surface and...
The Sardinian site, identified for the underground Einstein Telescope (ET) gravitational wave observatory, features a complex morphology with distinctive geological characteristics typical of stable crystalline basements. The area is also marked by deeply incised valleys, underscoring the need for a detailed and comprehensive understanding of the territory to support site assessment and risk...
We present the results of three temporary deployments of seismic arrays, installed in two vertices of a possible configuration of ET in the area of the Italian candidate site (Sardinia). The experiments, aimed at investigating the local noise sources and the seismic velocity structure, were carried out in 2021 and 2024 with different geometrical layouts, number of sensors and total recording...
We present the results of a gravimetric study conducted in the Sos Enattos mining site (northeastern Sardinia), an area identified as the Italian site for the potential underground installation of the Einstein Telescope (ET), a third-generation gravitational wave detector.
Currently, the ET project is in its preparatory phase, with efforts focused on performing feasibility studies for...
We present an evaluation of how site dependent noise can affect the signal to noise ratio (SNR) of compact binary coalescence (CBC) signals in the future 3rd generation gravitational wave (GW) detector Einstein Telescope (ET). The design of ET is currently pushing the scientific community to study its scientific potential with respect to known, and possibly unexpected, GW signals using its...
