Abstract:
The dynamical evolution of super star clusters has been investigated in dark-matter halos depicted with a cuspy- or soft-core density profile. Simulations show that (1) exponential bulges with central cusps form in both cases; (2) distinctive bulge formation fractions are derived for cuspy- and soft-core profiles; (3) the masses of the formed bulges are causally connected with the masses of nuclear clusters, which are heavier in the case of a cuspy-core profile; (4) massive, nuclear star clusters possibly form with no discernible bulges at different ages in cuspy- or soft-core cases. Based on comparisons with observations, both the soft- and cuspy-core dark matter density profiles are suitable to relevant dwarf galaxies.
