University of Zurich Researchers at UZH prepare for the expected observations of Euclid. They create and test advanced computer simulations that replicate how galaxies are distributed in space. Cosmologists study how Euclid's observations can be used to investigate the properties of the dark matter in our Universe. They examine the impact that "relativistic effects" have on Euclid’s observations. These effects occur because light from galaxies must travel through a Universe where matter is not evenly distributed to reach the telescope.
