Warped Disks and Inclined Rings around Galaxies [Hardcover]

Conference proceedings giving an in-depth review of research on the structure of galaxies.Tidal and dynamical interaction in galaxies are of importance in studying evolution. 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 conference where astronomers gathered to address these issues.Tidal and dynamical interaction in galaxies are of importance in studying evolution.

This book is a record of a conference where astronomers gathered to address these issues.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.Preface; Acknowledgements; Workshop participants; Group photograph; 1.
