These screenshots are from simulations aimed at understanding ultra-faint dwarf galaxies in the early Universe. (A) Dark matter distribution in our neighborhood in the Universe, the so called Local Group of galaxies. The two large dark matter halos correspond to those of the Milky Way and Andromeda galaxy; (B) zoom-in on the dark matter in and around a small halo ~700 million years after the Big Bang; (C) stars and gas in the centre of the small dark matter halo in one of our simulations.
