Optical Spectroscopy and Velocity Dispersions of SZ-Selected Galaxy Clusters

We present the design and the first results of a program of optical spectroscopy of galaxies in clusters detected in South Pole Telescope (SPT) data using the Sunyaev-Zel'dovich (SZ) effect, the spectral distortion of the cosmic microwave background from galaxy clusters. We use resampling for a...
