Deciphering Cold Dark Matter Substructurewith Subaru

Astronomical Institute, Tohoku University, Sendai

Abstract : Although the Cold Dark Mattersceniaro has been a widely accepted theoreticalparadigm for structure formation in the
Universe, it confronts serious discrepancies withobservations on small scales, i.e., galactic andsub-galactic scales. We report here on our recent
observational studies of the issue using theSubaru Telescope.
