Infrared Galaxies in Compact Groups
Astrophysics and Space Science, 2003IR properties of Compact Group (CG) galaxies are presented and compared with IR properties of isolated galaxies. Despite CGs displaying more E-SOs and optically bright galaxies, no differences are retrieved concerning FIR emission. The observed lack of strong FIR enhancement in the CG sample is not surprising when interpreting FIR sources in CGs as ...

Dwarf Galaxies in Nearby Groups of Galaxies
EAS Publications Series, 2011We 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.

Compact groups of compact galaxies. V
Astrophysics, 1976The lists of compact groups of compact galaxies are continued with a third list, which contains 54 new objects of this class discovered at Byurakan on the Palomar Sky Survey Charts. Searches were made in the +60, +66, +72/sup 0/ zones of the charts, which were completely surveyed except for regions near the galactic equator.

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.

Populations In Local Group Galaxies
Annual Review of Astronomy and Astrophysics, 1989developed primarily by W. Baade in the 1950s, was inspired by the apparent dichotomy of galaxy content. Some galaxies (spirals and irregulars) seemed to be made up largely of bright, blue stars, with an admixture of interstellar material, whereas others (ellipticals) seemed to be made up exclusively offaint red stars (13). Baade called the two kinds of

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.
