SHELS: The Hectospec Lensing Survey

Year: 2005

Type: article

Abstract: The Smithsonian Hectospec Lensing Survey (SHELS) combines a 10,000 galaxy deep complete redshift survey with a weak-lensing map from the Deep Lens Survey (Wittman et al.). We use maps of the velocity dispersion based on systems identified in the redshift survey to compare the three-dimensional matter distribution with the two-dimensional projection mapped by weak lensing. We demonstrate directly that the lensing map images the three-dimensional matter distribution obtained from the kinematic data.
