Before stellar evolution theory reached its present stage, galactic evolution ideas were tentative and depended not so much on physical arguments (e.g. galactic dynamics) but intuitive notions based on observations of galaxy shapes. Historically this is quite understandable.

Few galaxies are loners: almost all are members of groups of at least a dozen systems. The Milky Way is no exception. It is the second brightest in a group of three dozen, mostly dwarf, galaxies. The brightest member of the Local Galaxy Group is the Andromeda Spiral M31. The most luminous members of the Local Group, including all those visible with any

Mass determination in galaxies, groups of galaxies, and clusters of galaxies
IEEE Transactions on Plasma Science, 1990Computer simulations of interacting galaxies are used to determine the contribution of halos in disk galaxies. It appears that generally the halo is less massive than the disk. Redshift asymmetries are used to separate binary pairs from optical pairs in catalogs of galaxy pairs.

Galaxy Environment and Clusters of Galaxies
1994The galaxy population of clusters of galaxies is clearly different from the “field” population. While some of the static parameters, morphology for instance, are quite likely defined at formation, others, HI content, are strongly modified during the cluster lifetime due to the interaction of the objects with their environment.

Binary galaxies and groups of galaxies
1976NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. Using precisely defined identification criteria, a sample of 156 binary galaxy systems is selected from the Zwicky Catalog of Galaxies and Clusters of Galaxies.
