Restframe Optical Spectroscopic Classifications for Submillimeter Galaxies
(2006-11-10)
We report the results of a systematic near-infrared spectroscopic survey using the Subaru, VLT and Keck Telescopes of a sample of high redshift Ultra-luminous Infrared Galaxies (ULIRGs) mainly composed of submillimeter-selected ...
The stellar halo and outer disk of M33
(2006-08-10)
We present first results from a Keck/DEIMOS spectroscopic survey of red giant branch (RGB) stars in M33. The radial velocity distributions of the stars in our fields are well described by three Gaussian components, ...
