Subatech at Researchers' Night 2026
Dark matter, the quest for the invisible
In the Maxi room at Stereolux, Julien Masbou, a lecturer and researcher at Subatech Xenon team, took the audience on a journey into one of the great mysteries of contemporary physics: dark matter. For more than forty years, it has defied scientists. Invisible, silent, elusive, it resists all attempts at detection. Yet its attraction shapes the dance of galaxies, sculpts the structure of the cosmos, and imposes itself on our equations as a matter of course. Nothing holds together without it... and yet it still eludes our gaze. This presentation explored the research being conducted around the world, from underground laboratories to the far reaches of space, in an attempt to unravel this fascinating mystery.

La Throughout the evening, the public had the opportunity to discover science in a different way by talking directly with researchers during one-on-one meetings lasting a few minutes. Around forty scientists shared their work and answered visitors' questions on a variety of topics: digital technology, health, education, biology, psychology, and much more. Among them was Fanny Courtin, a researcher at Subatech Scenario team, participated in these meetings and shared with the public her research on the role of nuclear energy in the energy transition.
An evening rich in discoveries, exchanges, and wonder. Thank you to our scientists for their participation.
