Einstein Telescope science workshop for early career Researchers, February 18-20, 2026 at Sapienza University of Rome

The workshop wants to bring together young researchers actively involved in the activities of the Observational Science Board (OSB), Instrumental Science Board (ISB) and Site Characterization Board (SCB) of the Einstein Telescope. Leaving plenty of room for discussions, it will be a great occasion to share research and ideas, start projects, learn about new topics, and build collaborations.

It does not matter whether you like cosmology or pulsars, individual sources or backgrounds, data analysis, cryogenics, quantum noise reduction, or novel sensing and control systems … if you are young and interested in ET science, this is the right place!

After an opening session on the broad activities of ET ISB, OSB and SCB, the workshop is organized as a series of parallel sessions between OSB and ISB, each featuring two talks by expert early career researcher, laying the ground on the topics of relevance for each division, followed by ample room for discussion.

As additional information for all the ET enthusiasts: there is another workshop, the Einstein Telescope Research Infrastructure: Challenges and Long-Term Sustainability workshop, to be held in Rome at Sapienza University on February 16–17.
