Contact: CoG Meets ET

Danish delegation to the Einstein Telescope which included CoG group leaders, Prof. Niels Obers and Asst. Prof. Johan Samsing. — The Danish delegation to the Einstein Telescope, which included CoG members Niels Obers and Johann Samsing as well as NBI chair Joachim Mathiesen, in March 2026.

CoG group leaders Professor Niels Obers and Assistant Professor Johan Samsing, along with NBI chair Professor Joachim Mathiesen, represented the scientific front of gravitational wave physics at a danish delegation to the Einstein Telescope (March 2–3, 2026), joined by politicians, ambassadors and fellow scientists from around Denmark. The excursion included visits to the ET pathfinder in Maastricht, and the ET-CRISTAL in Liège.

The Einstein Telescope will within a couple of decades observe gravitational waves from merging black hole binaries in the entire observable universe (100.000 ~ 1.000.000 per year!). This will ignite a monumental shift in our understanding of the Universe, from the formation of black holes across cosmic time, to the nature of dark matter, dark energy, and possible new physics in relation to quantum gravity. The CoG science is tightly bound to the promise of this exceptional telescope. Exiting times ahead!
