Paper: Host galaxies and Environments of BL Lac Objects
Volume: 159, BL Lac Phenomenon

Abstract: Since the meeting on BL Lac objects in Como 10 years ago, a tremendous amount of data on BL Lac host galaxies and their environments was published. This has dramatically improved our understanding on the morphology of the host galaxies of BL Lac objects and their cluster environment, which will be reviewed. Special consideration will be given to the question, if interactions or merger processes might be the basic phenomenon for triggering the violent activity observed in BL Lac objects. The necessity of future observing programs using (very) large telescopes will be outlined.
