Abstract: The Milky Way: a product of cold dark matter The standard cosmological model includes the presumption that cold dark matter plays a major part in large-scale mass distribution in the Universe from the Big Bang to the present. Though successful in explaining large-scale events, until now simulations of galaxy formation using the cold dark matter model have failed to resolve certain smaller-scale structures. Now Diemand et al. have simulated the assembly of the dark matter 'halo' of the Milky Way at much better resolution than has been possible previously. The model then produces thousands of clumps surviving within the inner halo, some of them in the vicinity of the Solar System.
