Our understanding of galaxies has advanced significantly in recent years. Powerful computer simulations and detailed observations from ground- and space-based telescopes have been instrumental in this. This graduate textbook provides students with a complete, accessible introduction to modern galactic dynamics. The first two parts of the book define the astrophysical problems and the methods for building sound physical models. Next, coverage examines the observational properties and models of spiral then elliptical galaxies. A selection of exciting topics from contemporary research are also reviewed, including the formation and evolution of galaxies, cooling flows, accretion disks, and galaxies at high redshift. Throughout, the volume helps students develop a clear understanding and good physical intuition of the processes involved. Full derivations are provided for key results and helpful problems are included.

About the Author

Giuseppe Bertin is Professor of Physics at the University of Milan, Italy; previously he was in the faculty of the Scuola Normale Superiore, Pisa. He has also held several positions at the Massachusetts Institute of Technology and has been a member of the Kavli Institute for Theoretical Physics, University of California, Santa Barbara (in 2006 and 2009). Professor Bertin is also author of Spiral Structure in Galaxies: A Density Wave Theory with C. C. Lin, and editor of the proceedings of a series of three international workshops on plasmas in the laboratory and in the universe. He is the recipient of the Italian National Academy's Premio del Presidente della Repubblica in Science for 2013.
