The universe, as is now … WebThe formation history of individual galaxies is therefore potentially extremely complex, and precise predictions difficult. Nevertheless, hierarchical clustering models of galaxy …
Web20 de dez. de 2005 · If the favored hierarchical cosmological model is correct, then the Milky Way system should have accreted ~100-200 luminous satellite galaxies in the past ~12 Gyr. We model this process using a hybrid semianalytic plus N -body approach that distinguishes explicitly between the evolution of light and dark matter in accreted satellites.
