Studying galaxy structures using different wavebands enables us to observe a variety of intrinsic galactic features and to test the validity of underlying theories in detail. Density wave theory, originally proposed by C.C. Lin and F. Shu (Lin & Shu 1964), explains the nature of…

Molecular clouds are imperative to astronomy as the sites of all known star formation. The problem of how molecular clouds are formed in spiral galaxies is approached numerically, by modelling the response of a gas disk to a spiral potential. The importance of spiral shocks is h…
The main goal of the book is to introduce the reader to the world of spiral galaxies, how spirals were discovered, what they represent from a physical point of view, and what people have learned about the universe and the nature of galaxies in general from the study of spirals. …
Spiral galaxies are one of Nature's most majestic phenomena. Like huge pinwheels spinning in the boundless expanse of space, spiral galaxies are signposts telling us the nature and the history of the universe. The grandeur of the spirals lies not in their stunning beauty, but al…

"This book introduces the reader to the fascinating world of spiral galaxies by describing what has been learned about the universe from the study of spirals. Beginning with the work of late 18th and early 19th century astronomers who observed and catalogued large numbers of neb…
"This book summarizes the gathering of information on and the growing understanding of M33 from the 1920s, when Hubble first determined its true nature, to the 21st century, when the Hubble Telescope probed deeply into its many secrets. With its regular symmetrical spiral struct…
