Title:The Two-Phase Paradigm for Assembling Galaxies and their Globular Cluster Systems

Abstract:
I will discuss the new paradigm for the assembly of galaxies and their globular clusters (GC) systems 
emerging from recent theoretical work and supported by our imaging and spectroscopic data from the 
SLUGGS and SMEAGOL surveys. Data obtained with Suprime-Cam on Subaru and DEIMOS on Keck are 
compared to a variety of simulations of galaxy build-up in the early universe. Kinematic signatures, as well 
as metallicity and surface density distributions of the GCs and the underlying galaxy starlight appear to 
support two-phase galaxy formation scenarios. Early "in situ" formation and subsequent minor mergers may 
be the dominant mechanisms for building galaxies and their GC systems. Later major mergers may have 
been important only in a small minority of cases.
