Warped Disks and Inclined Rings around Galaxies

by Stefano Casertano, Penny D. Sackett, Franklin H. Briggs

Overview

Most galaxies lie in clusters, where tidal interactions are a significant force. Tidal and dynamical interactions and the features they cause in galaxies are important to the study of galactic evolution. For example, a large amount of data has been collected on dust-lane ellipticals, polar-ring galaxies, spirals with extended warps, and galaxies with inclined HI rings or unusual "tails." This book is a record of a meeting held at the University of Pittsburgh that provided an informal, yet focused environment for the interaction of astronomers who have addressed these questions with a wide variety of skills, techniques, and points of view.
