We present indications, based on a sample of 303 Abell clusters, for a relation between the dynamical state of clusters and the alignments of galaxy members with their parent cluster major-axis orientation as well as with the large-scale environment within which the clusters are embedded. The statistical results are complemented with a deep, wide-field case study of galaxy alignments in the cluster A521, which is characterized by multiple merging events (Maurogrdato et al.; Ferrari et al.) and… Expand
Orientation of Brighter Galaxies in Nearby Galaxy Clusters
A sample of 6188 nearby galaxy structures, complete to rF = 183 and containing at least 10 members each, was the observational basis for an investigation of the alignment of bright galaxies with theExpand
Intrinsic Alignment of Cluster Galaxies: the Redshift Evolution
We present measurements of two types of cluster galaxy alignments based on a volume limited and highly pure ($\ge$ 90%) sample of clusters from the GMBCG catalog derived from SDSS DR7. We detect aExpand
Primordial alignment of elliptical galaxies in intermediate redshift clusters
We measure primordial alignments for the red galaxies in the sample of eight massive galaxy clusters in the southern sky from the Cluster Lensing And Supernova survey with Hubble-Very Large TelescopeExpand
We present an analysis of the spatial orientations of galaxies in 247 optically selected rich Abell clusters which have at least 100 members in the considered area. We investigated the relationExpand
Anisotropy in the Distribution of Satellite Galaxy Orbits
Nearby clusters such as Virgo and Coma possess galaxy distributions that tend to be aligned with the principal axis of the cluster itself. This has also been confirmed by a recent statisticalExpand
Radial Alignment of Cluster Galaxies
We report the discovery of a statistically significant radial alignment of cluster galaxies in a sample of 85 X-ray-selected clusters observed in the Sloan Digital Sky Survey. The tendency forExpand
Analyzing the halo and galaxy catalogs from the Millennium Simulations at redshifts z = 0, 0.5, 1, we determine the alignment profiles of cluster galaxies by measuring the average alignments betweenExpand
On the Alignment of Galaxies in Clusters
We explore the distribution of position angles (PA) of galaxies in clusters. We selected for study the isolated clusters, since the distribution of the galaxy orientation in clusters with closeExpand
Constraints on the Alignment of Galaxies in Galaxy Clusters from $\sim$14,000 Spectroscopic Members
Torques acting on galaxies lead to physical alignments, but the resulting ellipticity correlations are difficult to predict. As they constitute a major contaminant for cosmic shear studies, it isExpand
The Axis-Ratio Distribution of Galaxy Clusters in the SDSS-C4 Catalog as a New Cosmological Probe
We analyze the C4 catalog of galaxy clusters from the Sloan Digital Sky Survey (SDSS) to investigate the axis-ratio distribution of the projected two-dimensional cluster profiles. We consider onlyExpand


The alignment of clusters using large-scale simulations
The alignment of clusters of galaxies with their nearest neighbours and between clus- ters within a supercluster is investigated using simulations of 512 3 dark matter par- ticles forCDM andCDMExpand
Correlations in the orientations of galaxy clusters
The relative orientation of clusters' major elongation axes and clusters' angular momenta is studied using a large N -body simulation in a box of 500  h -1  Mpc base length for a standard Λ CDMExpand
The Distribution of rich clusters of galaxies
A catalogue is prepared of 2712 rich clusters of galaxies found on the National Geographic Society--Palomar Observatory Sky Survey. From the catalogue, 1682 clusters are selected which meet specificExpand
Alignments of the Dominant Galaxies in Poor Clusters
We have examined the orientations of brightest cluster galaxies (BCGs) in poor MKW (Morgan, Kayser, and White) and AWM (Albert, White, and Morgan) clusters and find that, like their counterparts inExpand
Tidally Induced Elongation and Alignments of Galaxy Clusters
We show that tidal interaction among galaxy clusters can account for their observed alignments and very marked elongation and, consequently, that these characteristics of clusters are actuallyExpand
The Orientation of Galaxies in Clusters
We present a statistical analysis of directional data for the 10-20 brightest galaxies in a sample of 55 clusters. The data are derived from the digitization of Palomar 48 in. Schmidt telescopeExpand
The cluster substructure–alignment connection
Using a sample of 903 APM clusters we investigate whether their dynamical status, as evidenced by the presence of significant substructures, is related to the large-scale structure of the Universe.Expand
A search for galaxy-pancake alignments
Correlations between the position angles of galaxies and the major axes of their parent clusters or superclusters are searched for in two large galaxy catalogs, the UGC and the EUC, which cover mostExpand
Multiple merging events in Abell 521
We present a detailed spatial and dynamical analysis of the central ∼2.2 h75 −1 Mpc region of the galaxy cluster Abell 521 (z = 0.247), based on 238 spectra (of which 191 new measurements) obtainedExpand
Substructure: Clues to the Formation of Clusters of Galaxies
We have examined the spatial distribution of substructure in clusters of galaxies using Einstein X-ray observations. Subclusters are found to have a markedly anisotropic distribution that reflectsExpand
