The Project


SAURON will survey the kinematics and stellar populations of a representative sample of 72 nearby E, S0, and Sa galaxies drawn from both cluster and field environments. The survey is aimed at determining the intrinsic shape of the galaxies, their orbital structure, the mass-to-light ratio as a function of radius, the age and metallicity of their stellar populations, and the frequency of kinematically decoupled cores and nuclear black holes. Integral-field mapping uniquely connects measurements of the kinematics and stellar populations with the galaxy morphology. Already, the SAURON maps reveal an unexpected richness in the stellar kinematics, gaseous kinematics, and line-strength distributions of early-type galaxies.
