内容紹介 Compact groups of galaxies have been the subject of considerable interest since the discovery of the first compact group by Stephan in 1877. The Atlas of Compact Groups of Galaxies presents optical images of all 100 of these groups， assembled from CCD images obtained at the Canada-France-Hawaii Telescope (CFHT). The work is the result of a search undertaken using the entire set of Palomar Sky Survey redprints in the collections of the University of British Columbia for small groups of galaxies satisfying well-defined selection criteria. The atlas， combining the best available optical images of the groups with a concise tabulation of the relevant group data， is sure to become an indispensable reference for those engaged in the study of compact groups or interacting galaxies in general.
