Since May 2025, a working group has been preparing a multifaceted framework for site decision for the Einstein Telescope. They are expected to deliver a report with advice in the autumn of 2026. 👉Read more: einsteintelescope.eu/news/prepari...

The first joint ET-LISA Synergy Project is bringing together 40+ scientists to build shared code for joint gravitational-wave analyses. Combining observations across different frequency bands will reveal more about the early Universe than either detector alone. 🔗https://lnkd.in/ds5puvMb

Corner plot and posterior distributions comparing parameter estimation from LISA alone, the Einstein Telescope (ET) alone, and a joint LISA+ET analysis. Blue represents LISA, orange ET, and green the combined analysis. The joint LISA+ET results show substantially narrower posterior distributions for several parameters, illustrating the improved precision achieved through multiband gravitational-wave observations.

Conceptual illustration of joint LISA and Einstein Telescope observations of a binary black hole system. Three LISA spacecraft form a triangular laser interferometer in space above Earth, while gravitational-wave ripples extend toward the underground Einstein Telescope facility below the surface. Two black circles represent the binary source. The text “LISA × ET” appears prominently at the top.
