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 کاملAn H α survey of the rich cluster A 1689
We present results of an Hα survey in the rich cluster A 1689 at z = 0.18, using the LDSS++ spectrograph on the AAT. We obtained spectra covering redshifted Hα at z = 0.16–0.22, for 522 galaxies brighter than I = 22.5, covering a field of 8.7×8.7(∼ 1.1×1.1h Mpc at z = 0.18). We securely detect Hα emission in 46 of these galaxies; accounting for selection effects due to sampling and cluster memb...
