On Observations Collected at the Las Campanas Observatory of the Carnegie Institution of Washington
We report an analysis of the dynamical structure of clusters of galaxies from a survey of photometric and spectroscopic observations in the fields of southern Abell Clusters. We analyze the galaxy velocity field in extended regions up to 7h Mpc from cluster centers and we estimate mean velocity dispersions and their radial dependence. Only one from a total number of 41 Abell clusters does not c...
متن کاملDetection of Network Structure in the Las Campanas Redshift Survey
We employ a percolation technique developed for pointwise distributions to analyze two-dimensional projections of the three northern and three southern slices in the Las Campanas Redshift Survey. One of the goals of this paper is to compare the visual impressions of the structure within distributions with objective statistical analysis. We track the growth of the largest cluster as an indicator...
متن کاملStar Formation in Las Campanas Compact Groups
Compact groups (CGs) of galaxies offer an exceptional laboratory for the study of dense galaxian environments — where interactions, tidally induced activity, and mergers are expected to be at their highest rate of occurrence. Here, we present first results from a new catalogue of compact groups, one based upon the Las Campanas Redshift Survey (LCRS). Using the equivalent width of [O II] λ 3727,...
متن کاملTopology of the Las Campanas Redshift Survey
The topology of the Las Campanas Redshift Survey is analyzed using Minkowski functional statistics, taking into account the selection effects of the survey. The results are compared with the predictions of some toy models of structure formation, including the Standard Cold Dark Matter Model and topological defect-based models. All of the toy models have a scale invariant primordial spectrum of ...
متن کاملClusters and Superclusters in the Sloan and Las Campanas Surveys
We generate the 2-dimensional high-resolution density field of galaxies of the Early Data Release of the Sloan Digital Sky Survey and the Las Campanas Redshift Survey with a smoothing length 0.8 h Mpc to extract clusters and groups of galaxies, and a lowresolution field with a smoothing length 10 h Mpc to extract superclusters of galaxies. We investigate properties of density field clusters and...
