Jeder Punkt steht für eine Galaxie: Blaue Punkte markieren Galaxien im Zentrum von Dunkler-Materie-Klumpen, während rote Punkte Satelliten innerhalb dieser Klumpen bezeichnen.

Image extracted from the Euclid Flagship simulations catalogue. Each dot represents a galaxy: blue points mark galaxies at the centers of dark matter clumps, while red points denote satellites within them. Collectively, they trace the large-scale mass distribution of the Universe, forming clumps, filaments, and voids.
