Euclid starts seeing darkness

Consortium, People, Publication, Science / By

Euclid‘s core mission to study the nature of dark energy includes two central probes: one is tracking the expansion history of the Universe, the other traces structure formation over cosmic time. Ahead of the first cosmology results coming out in 2027, scientists have now published a first demonstration that Euclid can indeed trace massive structures dominated by usually invisible dark matter, using the technique of ‘weak gravitational lensing’.

Yannick has worked tirelessly to steer Euclid’s development from before its adoption as a mission by ESA to the first science results in 2025. Much of what the Consortium is today bears his mark – and the first flagship paper introducing the first Euclid science results is, and will be, a ‘Euclid Collaboration: Mellier et al.’

Late at night there had been some last minute work on the launcher and at 3AM the rocket apparently had still been lying horizontally, but a few hours later it could be seen standing upright with Euclid on top, sheltered by an ESA- and Euclid-themed fairing. The launch was on!
