Proposal Title: HI Evolution in Intermediate Redshift Galaxy Clusters
ABSTRACT:
We propose to use do test observations of the HI component of 26 intermediate redshift galaxy clusters. Our
primary goal is to use a well-dened sample of clusters to probe the role of the HI reservoir in the recent evolution
of cluster galaxies. These observations will be used in conjunction with existing optical and X-ray data to quantify
correlations between cluster X-ray luminosity, recent star formation, and HI mass.
