Spectroscopic Observations of Optically Selected Clusters of Galaxies from the Palomar Distant Cluster Survey
We have conducted a redshift survey of sixteen cluster candidates from the Palomar Distant Cluster Survey (PDCS) to determine both the density of PDCS clusters and the accuracy of the estimated redshifts presented in the PDCS catalog (Postman et al. 1996). We find that the matched-filter redshift estimate presented in the PDCS has an error σz = 0.06 in the redshift range 0.1 ≤ z ≤ 0.35 based on...
متن کاملThe Las Campanas Distant Cluster Survey - the Correlation Function
We present the first non-local (z >0.2) measurement of the cluster-cluster spatial correlation length, using data from the Las Campanas Distant Cluster Survey (LCDCS). We measure the angular correlation function for velocity-dispersion limited subsamples of the catalog at estimated redshifts of 0.35 ≤ zest < 0.575, and derive spatial correlation lengths for these clusters via the cosmological L...

We present a study of the surface density profiles of the clusters of galaxies from the Palomar Distant Cluster Survey (Postman et al. 1996). The survey contains a total of 79 clusters of galaxies, covering the estimated redshift range of 0.2 < ∼ z < ∼ 1.2. We have analyzed the richest clusters in this sample and find that the typical Palomar cluster has a surface density profile of r (r ≥ 0.10...

متن کاملTests of the Las Campanas Distant Cluster Survey from Confirmation Observations for the Eso Distant Cluster Survey1
The ESO Distant Cluster Survey (EDisCS) is a photometric and spectroscopic study of the galaxy cluster population at two epochs, z ≃ 0.5 and z ≃ 0.8, drawn from the Las Campanas Distant Cluster Survey (LCDCS). We report results from the initial candidate confirmation stage of the program and use these results to probe the properties of the LCDCS. Of the 30 candidates targeted, we find statistic...
