Scientific paper

We present continuing results of a large scale radial velocity survey of the Galactic bulge, using M giant stars selected from the 2MASS catalogue as targets for the CTIO 4m Hydra multi-object spectrograph. The purpose of this survey is to test dynamical models of the bulge and to detect the presence, if any, of cold stellar streams in the bulge and its vicinity. We report on over three years of observations of approximately 3500 stars which allow us to sample the kinematics the bulge major axis at -10RMR, DBR, and CDH acknowledge support from NSF grant AST-0709479 and grant GO-10868 from the Space Telescope Science Institute
