Title: Spectroscopy of Infrared Galaxies in Clusters to z = 1

Abstract: We are conducting a multi-wavelength study of a unique sample of galaxy clusters over the redshift range 0.3 < z < 1.1. A key component of this program is infrared imaging with the Spitzer Space Telescope at 24microns, which is sensitive to dust enshrouded star formation activity. Here we propose to obtain deep spectroscopic observations of a luminosity limited sample of infrared sources within the cluster fields, which are key to studying the evolution of the infrared galaxy population within clusters with redshift, in comparison to the field, and as a function of cluster properties, such as mass and dynamcal state. This will elucidate the nature and origin of the infrared galaxies in clusters, in the context of hierarchical formation and galaxy evolution in high-density regions. Our sample is unique in having the mass, redshift, and multi-wavelength coverage to address these important scientific issues.
