Query: Globular Cluster Systems and the Missing Satellite Problem: Implications
  for Cold Dark Matter Models   We analyze the metallicity distributions of globular clusters belonging to 28
early-type galaxies in the survey of Kundu & Whitmore (2001). A Monte Carlo
algorithm which simulates the chemical evolution of galaxies that grow
hierarchically via dissipationless mergers is used to determine the most
probable protogalactic mass function for each galaxy. Contrary to the claims of
Kundu & Whitmore, we find that the observed metallicity distributions are in
close agreement with the predictions of such hierarchical formation models. The
mass spectrum of protogalactic fragments for the galaxies in our sample has a
power-law behavior, with an exponent of roughly -2. This spectrum is
indistinguishable from the mass spectrum of dark matter halos predicted by cold
dark matter models for structure formation. We argue that these protogalactic
fragments, the likely sites of globular cluster formation in the early
universe, are the disrupted remains of the "missing" satellite galaxies
predicted by cold dark matter models. Our findings suggest that the solution to
the missing satellite problem is through the suppression of gas accretion in
low-mass halos after reionization, or via self-interacting dark matter, and
argue against models with suppressed small-scale power or warm dark matter.
