Title:A survey of globular cluster kinematics in early-type galaxies

Abstract:
To date, only a dozen GC systems have been kinematically investigated in detail. 
This small sample size has hindered attempts to search for global trends with 
host galaxy properties. 
We present an extended spectro-photometric survey of a dozen never-before 
studied GC systems,  thus doubling the sample of galaxies studied. For each GC 
system we exploit the combination of  Subaru/Suprime-Cam wide-field imaging
with spectra from Keck/DEIMOS multi-object spectrograph.
The surface density of the GCs is compared to the host galaxy surface 
brightness profile and the spatial distribution of planetary nebulae (another 
common kinematics tracer).  
We examine the rotation and velocity dispersion properties for each GC system 
and for their metal-rich and metal-poor subpopulations separately. Our survey 
results are integrated with those from the literature to provide a new insight 
into the kinematics and hence origin of GC systems.
