dc.descriptionObservational studies of cluster evolution over moderate redshift ranges (to z ~ 1) are a powerful tool for constraining cosmological parameters, yet a comprehensive knowledge of the properties of these clusters has been hitherto unattained. Using a highly efficient optical selection technique, the Red-Sequence Cluster Survey (RCS) has unearthed a large sample of high redshift cluster candidates. All six of the clusters from this sample which have been observed with the Chandra X-Ray Observatory were detected in the X-ray. These Chandra follow-up observations (0.64 < z < 1.0) indicate that the clusters are systematically less luminous than their similarly rich, X-ray selected counterparts at lower redshifts, though they are consistent with standard Lx-Tx relationships. Comparisons with X-ray selected samples suggest that the discrepancy may be due in part to systematic differences in the spatial structure of the X-ray emitting gas. Our initial results from Chandra follow-up observations of six RCS clusters are presented, including beta model parameters and spectral information.
