Dwarf Galaxy Alignment in Nearby Galaxy Clusters
Abstract
We investigate the alignment of dwarf galaxies selected from a sample of nearby (z<0.2) Abell galaxy clusters. Cluster galaxies are culled based on their location in the cluster color-magnitude diagram with respect to the host-cluster red-sequence. We explore the alignment of dwarf galaxies with the major axis of both the brightest cluster galaxy and the cluster as defined by the location of the red-sequence galaxies. In addition, we also look for an alignment between the major axis of cluster galaxies and a radius vector from the cluster center. We compare our results to predictions from N-body simulations of structure formation.
