The 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...
متن کاملClustering in the Las Campanas Distant Cluster Survey
We utilize a sample of galaxy clusters at 0.35<z<0.6 drawn from the Las Campanas Distant Cluster Survey (LCDCS) to provide the first non-local constraint on the clustercluster spatial correlation function. The LCDCS catalog, which covers an effective area of 69 square degrees, contains over 1000 cluster candidates. Estimates of the redshift and velocity dispersion exist for all candidates, whic...
متن کاملAn Overview of the Las Campanas Distant Cluster Survey
We present the Las Campanas Distant Cluster Survey, which has produced over a thousand galaxy cluster candidates at 0.35 < z < 1.1 (see Gonzalez et al. 2001 for the full catalog). We discuss the technique that enabled us to use short (∼ 3 min) exposures and a small (1m) telescope to efficiently survey ∼ 130 sq. deg. of sky. Follow-up imaging and spectroscopy using a wide array of telescopes inc...
متن کاملRevisiting Brightest Cluster Galaxy Evolution with the Las Campanas Distant Cluster Survey
We investigate the influence of environment on brightest cluster galaxy (BCG) evolution using a sample of 63 clusters at 0.3 ≤ z ≤ 0.9 drawn primarily from the Las Campanas Distant Cluster Survey and follow-up V , I, and K ′ photometry. The luminosity evolution of the entire BCG sample is not adequately described by a single evolutionary model. Using the integrated light from the cluster detect...
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...
