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

Dwarf Galaxies in Nearby Groups of Galaxies [PDF]
EAS Publications Series, 2011 We have confirmed 19 new dwarf members in five nearby (z ≤ 0.014) groups of galaxies, measured their photometric characteristics and compared the photometric scaling relations of the late-type dwarf galaxies in the field, group and cluster environments.

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.

The results of recent statistical analyses of extensive samples of galaxy groups are reviewed. Most of the groups appear to be unrelaxed systems which are far from virial equilibrium. With the introduction of a corresponding correction factor to standard virial mass estimates, the latest catalogues of groups point to M/L B ≈ 400 M⊙/L⊙ (H0 = 100kms−1 ...

If galaxies in the universe were uniformly distributed we would have had to find another excuse to enjoy ourselves in Trieste. Fortunately groups of galaxies are a sufficiently messy subject to require at least one more meeting.

Dwarf Galaxies in Nearby Galaxy Groups
2011The nearby Universe is populated mostly by galaxy groups, whose dominant galaxies are surrounded by dwarf galaxies. We have observed nearby galaxy groups in a distance range of 13–34 Mpc with a variety of different morphologies, densities, and richness in order to investigate their dwarf galaxy populations and to detect tidal streams in the halos of ...
