The German ET Community Meeting in Hamburg
31.01.2025 The Science City Hamburg Bahrenfeld hosted the German ET Community, with more than 150 in-person participants underwriting the strong enthusiasm of the German community to work towards the realisation of the Einstein Telescope and the maximisation of its science. Highlights of the meeting included the keynote talk by Samaya Nissanke about Multi-Messenger Astrophysics today and in the ET era and talks about the status of ET and the ET Project by Harald Lück and Andreas Freise – and the social dinner on the Cap San Diego museum ship, which allowed the hosting city to showcase their strong maritime tradition. The German ET Community acknowledges the generous support by the…

Prospects in Theoretical Physics 2025:Gravitational Waves from Theory to Observation, July 14-25, 2025, Princeton
Prospects in Theoretical Physics 2025:Gravitational Waves from Theory to Observation, July 14-25, 2025, Princeton PiTP is an intensive two-week summer program designed for advanced graduate students and postdoctoral scholars. The program will be held from July 14-25, 2025 at the Institute for Advanced Study, Princeton, NJ. The school will explore the field of gravitational wave physics and astrophysics, bridging the gap between theory and observation. Gravitational waves offer a unique window into the Universe, allowing us to probe extreme astrophysical environments and primordial cosmological epochs. School Website

ULTRA-PURE SILICON
11.12.2024 ULTRA-PURE SILICON Development of High-purity Silicon Mirrors for the Einstein Telescope The Einstein Telescope (ET) will be a third-generation detector with a tenfold increase in sensitivity for gravitational waves that will expand the observing window for previously hidden cosmic events. ET will have the potential to discover new, so far unknown sources of gravitational waves. To achieve this extremely high sensitivity, the interferometer’s mirrors will be made of silicon crystals. Crystalline silicon offers excellent material properties for detection at cryogenic temperatures, where the interferometer will operate to minimise thermal noise. Read more

Leibniz-Institut für Kristallzüchtung (IKZ) has joined ET
12.12.2024 The Leibniz-Institut für Kristallzüchtung (IKZ) in Berlin has joined the international Einstein Telescope (ET) collaboration as a research unit (RU-Berlin). The IKZ is a state-of-the-art competence center for crystalline materials. Its mission for ET is to provide crystalline silicon material and crystal growth know-how for the production of ET interferometer mirror and mirror suspensions. Silicon crystal growth using the Float-Zone (FZ) method is a long-standing expertise at the IKZ. The crucible-free FZ technique stands out for its ability to produce silicon crystals of ultra-high purity and crystalline perfection. Contactless induction heating of a molten zone held by surface tension forces allows growth without contamination. In the semiconductor industry, the…
