1989A&A...219...34K The group environment of Seyfert galaxies. I W. Kollatschny and K.J. Fricke Universitatssternwarte Gottingen, Geismarlandstr. 11, D-3400 Gottingen, Federal Republic of Germany Received June 30, accepted October 22, 1988 Summary. On Palomar and ESO Schmidt plates loose groups of ~ 1 Mpc size are identified. Spectroscopy of 15 such groups containing a Seyfert galaxy and 9 loose groups without a Seyfert galaxy comprising a total number of 113 galaxies is presented. Using qualitative and absolute optical spectroscopic criteria the activity pattern in groups is described. Galaxies with strong emission-line activity are found in Seyfert groups out to distances ~ 300 kpc away from the Seyfert galaxy while in non-Seyfert groups such galaxies are virtually absent. The theoretical implications of these results with regard to the structural and dynamical conditions for tidally induced starburst and Seyfert activity are discussed. Key words: galaxies: active, Seyfert, nuclei of - surveys - clusters: of galaxies
