Galactic Astronomy: A Review of Binney and Merrifield’s PDF Book

Galactic astronomy is the study of the structure, formation, and evolution of galaxies, both in our own Milky Way and in the distant universe. It is a fascinating and rapidly developing field that combines observations from various wavelengths and techniques with theoretical models and simulations. One of the most comprehensive and authoritative books on this topic is Galactic Astronomy by James Binney and Michael Merrifield, published by Princeton University Press in 1998.

In this article, we will review the main features and contents of this book, and highlight its strengths and weaknesses. We will also compare it with other similar books on galactic astronomy, and discuss its relevance and usefulness for students and researchers in the field.

Overview of the book

Galactic Astronomy is a textbook that covers the phenomenology of galaxies, that is, the observable properties and characteristics of these complex systems. It does not deal with the dynamical aspects of galaxies, such as their orbits, stability, and interactions, which are treated in another book by Binney and Scott Tremaine, Galactic Dynamics. The book is intended for graduate students and advanced undergraduates who have a background in undergraduate physics, as well as for professionals who want to update their knowledge on the subject.

The book consists of 12 chapters, organized into four parts. The first part introduces the basic astronomical concepts and tools necessary to understand the properties of galaxies, such as coordinate systems, magnitudes and colors, the phenomenology of stars, the theory of stellar and chemical evolution, and the measurement of astronomical distances. The second part covers the phenomenology of external galaxies, such as their morphology, classification, luminosity function, color-magnitude relation, stellar populations, star formation rate, metallicity, gas content, dust extinction, and radio emission. The third part focuses on the Milky Way galaxy, describing its structure and kinematics in detail, as well as its star clusters, interstellar medium, spiral arms, bulge, halo, and central black hole. The fourth part deals with the kinematics of external galaxies, such as their rotation curves, velocity dispersion profiles, mass-to-light ratios, Tully-Fisher relation, Faber-Jackson relation, fundamental plane, virial theorem, dark matter, gravitational lensing, and galaxy groups and clusters.

The book is well-written and clear, with a logical and coherent structure. It emphasizes the observational basis for current understanding of galactic astronomy, with references to the original literature. It also includes many figures and tables that illustrate the data and models discussed in the text. Each chapter ends with a summary of the main points and a set of problems that test the reader’s comprehension and application of the concepts. The book also has an extensive bibliography that lists more than 1000 sources for further reading.

Strengths and weaknesses of the book

One of the main strengths of Galactic Astronomy is its breadth and depth of coverage. It provides a comprehensive overview of the field that incorporates both classical results and recent advances. It covers both observational and theoretical aspects of galactic astronomy,

and discusses the strengths and limitations of various methods and models. It also presents a balanced and critical perspective on the current debates and controversies in the field, such as the nature and origin of the dark matter, the formation and evolution of galaxies, and the role of feedback processes. The book is also updated with the latest data and discoveries from various surveys and missions, such as the Sloan Digital Sky Survey, the Two Micron All Sky Survey, the Hipparcos satellite, the Hubble Space Telescope, and the Wilkinson Microwave Anisotropy Probe.

Another strength of Galactic Astronomy is its pedagogical value. It explains the concepts and techniques in a clear and accessible way, with examples and exercises that help the reader to apply them to real data. It also provides a historical and conceptual context for the development of the field, highlighting the key observations and ideas that led to the current understanding of galaxies. The book is also well-organized and self-contained, with cross-references and appendices that facilitate the navigation and comprehension of the material.

A possible weakness of Galactic Astronomy is its length and level of detail. The book is quite long and dense, with more than 800 pages and 12 chapters. It covers a lot of topics and aspects of galactic astronomy, some of which may not be relevant or interesting for every reader. It also goes into a lot of detail and mathematical derivation for some topics, which may be too advanced or technical for some readers. The book may be more suitable for readers who have a strong background and interest in galactic astronomy, rather than for beginners or casual readers.

Another possible weakness of Galactic Astronomy is its age and availability. The book was published in 1998, which means that it does not include some of the most recent developments and discoveries in the field, such as the Gaia satellite, the Large Synoptic Survey Telescope, the James Webb Space Telescope, and the Square Kilometre Array. The book is also out of print and hard to find in some libraries or online stores. The book may be less relevant or useful for readers who want to learn about the latest state-of-the-art in galactic astronomy.

Comparison with other books on galactic astronomy

There are several other books on galactic astronomy that can be compared with Galactic Astronomy by Binney and Merrifield. Some of them are:

Galactic Dynamics by Binney and Tremaine: This is a companion book to Galactic Astronomy that focuses on the dynamical aspects of galaxies, such as their orbits, stability, and interactions. It covers topics such as collisionless systems, collisional systems, disk galaxies, elliptical galaxies, spiral structure, galaxy mergers, active galactic nuclei, cosmology, and numerical methods. It is a more advanced and mathematical book than Galactic Astronomy, aimed at graduate students and researchers who want to learn about the theory and modeling of galactic dynamics.
An Introduction to Modern Astrophysics by Carroll and Ostlie: This is a general textbook on astrophysics that covers a wide range of topics, such as stellar structure and evolution, stellar atmospheres and spectra, binary stars, star clusters,
the interstellar medium, the Milky Way galaxy, external galaxies, active galactic nuclei, cosmology, and high-energy astrophysics. It includes a chapter on galactic astronomy that covers some of the same topics as Galactic Astronomy by Binney and Merrifield, but in a more concise and introductory way. It is a more general and accessible book than Galactic Astronomy, aimed at undergraduate students and general readers who want to learn about the basics of astrophysics.
Galaxies in the Universe: An Introduction by Sparke and Gallagher: This is another textbook on galactic astronomy that covers topics such as the properties and classification of galaxies, the Milky Way galaxy, the interstellar medium, star formation and evolution, galaxy dynamics, galaxy interactions and mergers, active galactic nuclei, galaxy clusters and groups, cosmology, and galaxy formation and evolution. It is a more updated and concise book than Galactic Astronomy by Binney and Merrifield, published in 2007. It is also more focused and streamlined than Galactic Astronomy, omitting some of the more technical or specialized topics. It is a more intermediate and balanced book than Galactic Astronomy, aimed at upper-level undergraduate students and graduate students who want to learn about the main aspects of galactic astronomy.
