(Proposal Title) 
Exploring Masses, Profiles and Shapes of Dark Matter Halos with Cluster 
Weak Lensing III

(Abstract)
To complete our scientific goals approved in 2010A and 2010B, we propose to 
complete our systematic multi-wavelength survey of X-ray luminous clusters. 
Thanks to the unique capability of Suprime-Cam, the high-quality lensing data 
allow for the accurate reconstruction of total mass distribution in each 
cluster. Based on the statistics of our complete volume-limited cluster 
samples, we aim to (1) construct the cluster mass-observable scaling relations 
by comparing the lensing masses with other observables, X-ray (XMM), the 
Sunyaev-Zelfdovich effect (SZA), and dynamical mass estimates (MMT/Hectospec),
 (2) confirm whether the Subaru lensing data is consistent with the Navarro-
Frenk-White model predictions for the cluster mass distribution over scales 
ranging from tens of kpc to a few Mpc, and (3) detect dark matter halo 
ellipticity from the full two-dimensional analysis of background galaxy 
images. The full Subaru/XMM/SZA dataset on this large volume-limited sample of 
clusters will deliver a unique legacy for future cosmological and astrophysical
 studies of galaxy clusters.
