Caption

(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-1 and C-2) stars and gaseous material in the simulated ultra faint dwarf galaxy, hosted in the centre of the small dark matter halo in panel B, in two different models for the conditions of the early Universe. We can see how the ultra-faint dwarf galaxy changes its properties depending on the model. The scale on each image is in units of light years.  (Image credit: J Sureda/A Fattahi/S Brown/S Avraham)
