SUMMARY:Globular clusters systems and their host dark matter halos
DESCRIPTION:Globular clusters systems and their host dark matter halos\nDr.
  Lee Spitler\n\nIn the Λ-CDM galaxy formation paradigm, the star fo
 rmation history of a galaxy is coupled to the total mass of its dark matte
 r halo through processes like galaxy-galaxy merging, satellite accretion, 
 and gas retention.  Globular cluster formation is known to coincide with s
 trong star formation events in the early Universe.  To develop an accurate
  model of galaxy formation, the relationship between such systems and thei
 r hosting dark matter halos must be understood.  Employing weak gravitatio
 nal lensing galaxy mass analysis, we have discovered that the number of gl
 obular clusters in a given galaxy is directly proportional to its total da
 rk matter halo mass.  This result holds in both dwarf and giant elliptical
 s, spirals and in all types of galaxy environments. I will present these o
 bservations and initiate a discussion on the implications for scenarios of
  globular cluster system formation and evolution.
