Reader Reviews
Any instructor who has used the first edition of this book can attest to its fine quality of presentation and its didactic power. The second edition continues this tradition, and in addition offers more material that reflects the many discoveries and developments in astrophysics that have taken place since the first edition. The observational tools in astronomy have become even more refined over the years since the first edition along with computing power, and these two facts combined with a robust community of theoreticians have pushed the limits of astrophysical knowledge. This book is of course a sizable one, and this reviewer did not read it in its entirety, but instead focused on those sections that addressed the new developments since the first edition. One of the interesting topics that are discussed in the book whose explanation was not found in the first edition is that of gamma ray bursts. After a brief historical discussion of their first detection, the authors address the question as to the origin of the bursts, i.e. whether galactic or extragalactic. They perform some rudimentary calculations that show how energetic the bursts must be if they were located in the solar system or from a distant galaxy. Early thinking on the cause of gamma ray bursts associated them with neutron stars, but the authors explain the problems with this explanation, and most interestingly, give arguments that support the assertion that there is an edge to the distribution of the gamma sources. Clever observational techniques resulted in the conclusion that gamma ray bursts are extragalactic. The `collapsar' and `supranova' models of gamma ray bursts are discussed, but the discussion is way too brief for those who want the in-depth details of these models. However the authors give up-to-date references for readers who want to dig deeper. From a perusal of these references it is apparent that the supranova model has gained the most popularity at the present time, even though some of the observations cannot as yet be reconciled with this model. Another topic of great current interest is that of dark matter, which is discussed in the last chapter of the book, and which the authors describe as one of the most important theoretical issues in cosmological astrophysics. This discussion is also short, but references are given, and its inclusion since the first edition reflects the theoretical interest. The paucity of experimental evidence for the candidates of dark matter has stymied theoretical developments, with most of the effort devoted to putting bounds on the candidates, such as axions and weakly interacting massive particles. No doubt this book will continue to be used in the classroom in years to come, and new discoveries will be included in future editions. With the CERN collider coming on line in the next few years, everyone interested will see the interplay between high-energy physics and astrophysics. The collider will give the theoretical astrophysical community new bounds on cosmological quantities, and in fact may open up whole new lines of research, all of it exciting, and proof positive that the twenty-first century is the most exciting time to be alive.
