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.

Astronomical observations now reach far enough back in time, in enough depth and detail, to reveal the history of galaxies since their formation. The early Universe contained a network of gas clouds that filled much of the space between the young galaxies, where stars were forming at a high rate.

On the distribution of galaxies and galaxy clusters
New Vistas in Astrophysics, 2000The fact that galaxy and galaxy clusters distributions exhibit fractal properties is well established since twenty years 1 ,2. Nowadays, the controversy concerns the range of the fractal regime , the value of the fractal dimension and the eventual presence of a cross-over to homogeneity 3,4,5 In this paper we briefly review the methods of analysis ...

The First Galaxies and Galaxy Clusters
2009Obvious targets for Extremely Large Telescopes are high-redshift galaxies and galaxy (proto-)clusters. However, due to the extremely small field-of-view of such telescopes, finding such objects, notably the rarer proto-clusters, is best be done using other facilities.

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.
