Review: Review of the first edition: 'A fresh and exciting introduction to modern galactic physics on the grand scale, and of its connections to other broad domains of contemporary physics. Graduate students in particular, will appreciate the clarity of presentation.' Bruno Coppi, Massachusetts Institute of Technology Review of the first edition: 'This book fills a major need for a graduate-level, physically-based introduction to galaxies, and will be of a very wide appeal as a course text. The original approach leads to a rich physical intuition of real kinematical systems. A particular strength is the detailed analysis of the limitations of current methods and theories.' Gerry Gilmore, University of Cambridge Review of the first edition: 'Giuseppe Bertin's Dynamics of Galaxies is an elucidating account of a graduate course given by Bertin over the past two decades ... His] book is particularly useful for students interested in mathematical methods of galactic dynamics. Bertin's comparisons between galactic dynamics and plasma physics are also innovative and illustrative.' Debra Elmegreen, Physics Today

This is a concise introduction to modern astrophysics for physicists, with a focus on galaxy dynamics and the discovery of dark matter halos in galaxies. Part I summarizes important discoveries in observational astronomy and astrophysics, in a manner accessible to those who are new to the topic. Building on this foundation, Part II describes the study of dark matter and provides more detail on galactic dynamics. Important physical concepts that form the basis of key astrophysical phenomena are explained, avoiding unnecessary technicalities and complex derivations. The approach is semi-empirical and emphasizes the importance of key measurements and observations in formulating fundamental theoretical questions and developing their solutions. Students are encouraged to develop a deep understanding of major discoveries and contemporary research topics, beyond the simple application of practical models and formulae, as a bridge to more advanced study in astrophysics.
