Cold Dark Matter, Small-Scale Power, and Halo Substructure: Clues from Globular Clusters
Patrick Cote (Rutgers, The State University of New Jersey)
Cold dark matter (CDM) models offer an attractive and popular theory for
the formation of cosmological structure. However, it has become clear that
the success of such models on large spatial scales does not extend down
to the levels of galaxies. A particularly worrisome problem for CDM models
is the apparent underabundance of dwarf galaxies at low-redshift: i.e., the
so-called "missing satellite problem". In this talk, I will discuss how
observations of globular clusters in nearby galaxies, including the Milky
Way, may help us to explain this longstanding puzzle.
