1993ApJ...405..413P COMPACT GROUPS OF GALAXIES AND LARGE-SCALE STRUCTURE G. G. C. PALUMBO, P. SARACCO, C. MENDES DE OLIVEIRA, P. HICKSON, V. TORNATORE, AND G. C. BAIESI-PILLASTRINI Received 1992 March 2; accepted 1992 July 16 ABSTRACT The relative orientation of a homogeneous sample of 92 compact groups of galaxies taken from Hickson's catalog is investigated. No evidence is found for these groups of galaxies to be aligned with either their nearest neighbors or with Abell clusters. However, a weak indication of alignment is found for groups connected in large structures such as "chains" and/or "filaments." Two concentrations are found: one of 17 groups extends for 93 h^-1^ Mpc, the other of 15 groups for 83 h^-1^ Mpc. Both have an average recession velocity of ~6300 km s^-1^. The alignment of the groups in the concentrations may be suggestive of a real effect. This result supports the argument that group orientations reflect their origin in chainlike or filamentary protosuperclusters. Subject headings: galaxies: clustering - large-scale structure of universe
