Nuclear Activity of Galaxies within Groups
Published online by Cambridge University Press: 04 August 2017
Abstract
Results from a spectroscopic survey of groups around Seyfert galaxies and of an appropriate control sample are reported. The groups are ≲1 Mpc across. A nuclear spectroscopic “activity class” is assigned to each group member. The active types show a peaked distribution around the Seyfert galaxy and are confined to a critical radius ~300 kpc while the nonactive members are uniformly distributed over the whole extent of the groups. These results are briefly discussed.
