The field of gravitational waves is one of the most promising areas for research in fundamental physics, astrophysics, nuclear physics, and cosmology. It is, therefore, not surprising that a project with such a wide impact in terms of knowledge and innovation as the Einstein Telescope has already attracted the scientific and technological interest of a large and heterogeneous international community, both European and global.
The ET needs institutional and political support and the synergy of scientific and industrial expertise, such as all large-scale scientific projects that stem from a deep capacity for future vision and innovative design, which is based on large experiments and requires considerable joint investments.
The ET’s ESFRI project is organised as a consortium, led by Italy and the Netherlands, with the political support of Belgium, Poland, and Spain. The ET community, which has been active for more than 15 years, has been organised into an international scientific collaboration since 2022. Such collaboration consists of more than 1,400 experts, researchers, engineers, technicians, and data scientists, belonging to more than 220 institutions spread across 23 nations, both in Europe (Czech Republic, France, Germany, Greece, Hungary, Switzerland, and United Kingdom), and worldwide.
Currently, the work of scientists, engineers, and technicians is focusing on the study of the configuration of the detector, designing and developing enabling technologies, in order to prepare the data analysis methods, and build the astrophysical models that will be used to interpret the measurements and data collected. In addition, characterisation studies are underway for two candidate sites to host the Einstein Telescope: one in Sardinia, in the area of the decommissioned Sos Enattos mine (Nuoro), and one near the border between the Netherlands, Belgium, and Germany
