Proposal Title: 21 cm HI Observations of intermediate­z Clusters of Galaxies
ABSTRACT:
We propose to detect and study the global neutral atomic gas properties of a sample of 4 intermediate­redshifts
(0.15 clusters observations with the GBT. We plan to study the neutral gas content in these structures, not only to
derive the masses, but to understand the evolution of the clusters space density. As the clusters have been selected
using ROSAT and SDSS, we will be able to compare our results with X­ray data. In fact, we will test the
correlation between the HI deficiency and the X­ray emitting intra­cluster medium.
