On 2-3 September, astroparticle physics representatives from throughout Europe met in Geneva to fine-tune input for the future European Astroparticle Physics Strategy 2027-2036.

The Einstein Telescope was included in the draft roadmap that served as input for this meeting, referred to as the next major flagship project for gravitational-wave astronomy, and recognised for its value for multi-messenger astronomy and role in the full astroparticle physics landscape. In the community survey feeding into the roadmap, the Einstein Telescope was also the most frequently cited next-generation infrastructure to be included.

During the meeting, the Einstein Telescope, represented by Michele Maggiore, featured prominently in the session on multi-messenger astronomy.

The final APPEC roadmap 2027-2036 is expected to be delivered by the end of this year. A moment to look forward to!

Three official candidate sites are currently in the running to host the Einstein Telescope: Sardinia, the Euregio Meuse-Rhine and Lusatia.

The future decision will need to take a wide range of factors into account. To support this process, a dedicated working group has been developing a decision-making framework since May 2025.
Its role is not to choose between the three candidate sites, but to recommend which criteria should matter, how they could be weighed and what evidence should be provided by the candidates.

The group is expected to deliver its report in autumn 2026.

The future of gravitational-wave astronomy will be built through collaboration.🤝
Since January 2026, more than 40 members of the Einstein Telescope Collaboration and the LISA Consortium have been working together in the first official ET–LISA Synergy Project.

The goal is to develop a shared analysis code that will allow scientists to combine observations from different GW detectors. Because ET and LISA will observe different parts of the GW spectrum, analysing their data together will provide a more complete picture of signals from across the Universe, including those originating in its earliest moments.

Beyond the software itself, the project is also strengthening collaboration between two major GW communities, creating common tools and standards that can be extended to future observatories such as Cosmic Explorer.

As the project coordinators, Antonio J. Iovino and Gabriele Perna, explain:

"Preliminary tests already showed the extreme gain in characterising GW signals when more detectors are considered together and we're excited to explore the wider cosmological implications!"

Meet Romano Meijer, System Engineer at the Einstein Telescope Organisation Project Office, based at Nikhef.

With a background in precision mechatronics and optomechanical systems engineering, Romano helps keep the big picture in focus. His work includes establishing and applying ET’s model-based systems-engineering standards, as well as managing requirements, interfaces, configuration and technical baselines.

💬 "What inspires me most about ET is its amazing scientific potential and the multidisciplinary environment of detector and underground infrastructure design. A well-managed design means that we know that we satisfy the purpose of ET (science), understand the dependencies between systems (technology) and can confidently track the impact of changes made to the design (time)."

When he's not thinking about complex engineering systems, Romano enjoys exploring the night sky from the other side of the telescope. On clear evenings, you'll often find him capturing stunning images of the stars with his own astrophotography setup. 🔭✨
Every person brings a unique path to ET. And that’s what makes our community so exciting!

July is not over yet, but it has already brought several important developments for the Einstein Telescope across Europe!

🔹 ETO Funders Group meets in Rome
The Einstein Telescope Organisation’s Funders Group convened in Rome on 16 July. ETO staff and directors shared updates on the geometry comparison report, the ongoing collaboration with CERN, and frameworks for resources and personnel.

🔹 Three milestones for ET in Sardinia
On 17 July, Italian institutions INFN - Istituto Nazionale di Fisica Nucleare, INAF and INGV Istituto Nazionale di Geofisica e Vulcanologia, together with Germany’s TU Dresden and Karlsruher Institut für Technologie (KIT), signed an agreement strengthening cooperation between the Sardinia and Lusatia candidate sites - a further step towards a joint candidacy to host ET.
Later that day, a new ET Information Point was inaugurated in Lula, providing an accessible space where local communities can learn about the project and ask questions directly.
The day concluded at the former Sos Enattos mine with a groundbreaking ceremony for the future ET-SUnLab research centre. The facility will support ET-related R&D, low-noise physics experiments, a geophysical observatory and MezzoCielo, a large-aperture ground-based telescope.

🔹 Dutch consortium innovates vibration-free cooling
The Zero-vibration Sorption Cryocooler consortium is developing a high-power sorption cooler, to be tested at the laboratory in Maastricht.

🔹 EMR region launches sustainable computing project
The SCOPE project (Sustainable Computing Prototype for the Einstein Telescope) brings together eleven partners to develop sustainable computing infrastructure over the next three years

While the Einstein Telescope community was busy with the XVI ET Symposium, many other important developments were taking place across Europe in June.
🔹In Italy, the national ET community met at INFN – Laboratori Nazionali di Frascati to discuss the status of the Italian candidacy and the results of , the major infrastructure project supporting the Sos Enattos candidate site.
🔹In the Euregio Meuse-Rhine, Wallonia’s Parliament unanimously backed the EMR candidacy, while updates from the region highlighted progress in logistics planning, industrial mobilisation and public engagement.
🔹In Wallonia, the world’s largest mono-crystalline silicon mirror has been produced for ET. The 45-centimetre mirror will support the development of future gravitational-wave detector technologies at the ET-CRISTAL laboratory in Liège (University of Liège).
🔹In Flanders, the ET ECHO exhibition at Corda Campus is bringing science, technology and entrepreneurship together, while Technopolis is introducing young visitors to through a dedicated ET exhibition and themed activities.
🎬 The full-dome documentary "Einstein Telescope: Listening to the Universe Beyond the Stars" - nationally premiered on 11 February at the Rome Planetarium - was screened at the Fulldome Festival in Fukuoka during (VIS Virtual Immersions in Science).
🔹 Education and skills are also moving forward, with the hashtag project developing a cross-border curriculum in mechatronics and future technologies for the Euregio.
🔹 In Upper Lusatia, seismic measurement data from one of the monitoring stations are now available online. The region also hosted dialogue events with local businesses and residents, offering updates on site investigations and the potential regional impact of ET.

News from the world. The new LIGO-Virgo-KAGRA catalog published recently adds 161 events detected by current gravitational-wave detectors, bringing the total number of detected gravitational-wave signals to 390. Beyond the growing number of detections, what should we remember from this catalog?

✨ The most precise sky localization ever achieved for a gravitational-wave source
✨ The clearest gravitational-wave signal recorded so far
✨ New evidence for “second-generation” black holes - black holes born from earlier black hole mergers

Step by step, gravitational waves are revealing new stories about the Universe. With the Einstein Telescope in the future, we can expect much more: more detections, greater sensitivity, and a deeper view of the Universe.
