Formulae and mathematical derivations are frequent more advanced or detailed subsections are printed in smaller characters , allowing the student to go beyond pure notions and to grasp the nature of astrophysical phenomena and processes in a quantitative way. Moreover, every important sub-field of research in extragalactic astronomy and cosmology is introduced and discussed, with a good balance between theory and observations, and the text is fully uptodate.
Extragalactic Astronomy and Cosmology: An Introduction - Peter Schneider - كتب Google
Not surprisingly, the first chapter is a general introduction to the subject, but for its length more than 40 pages and content it could stand by itself as an accessible review. It is divided into two main parts: the first one gives a synthesis of the scientific theme of the book, while the second one describes the present main observational facilities on Earth and in space at different wavelengths.
The second chapter is devoted to the Milky Way as a galaxy: it includes classical themes such as the measurement of star distances, the structure and kinematics of the Milky Way, but also microlensing and the search for dark matter in the Milky Way, and the evidence showing the presence of a black hole in its center.
The following chapter is devoted to the world of galaxies: their classification, their morphologies and colors, the dynamics of ellipticals and the rotation curves of spirals, the scaling relations Faber-Jackson, Tully-Fisher, the Fundamental Plane , the Population Synthesis models, the chemical evolution, the supermassive black holes in their center, the estimate of distances and the luminosity function, and the role of galaxies as gravitational lenses note that this is not an exhaustive list of the many properties of galaxies discussed by the author.
The fourth chapter, the first devoted to cosmology, presents the homogeneous world models, describing the standard Big Bang model with the main theoretical framework and the supporting observational evidence.
The author presents a classical Newtonian derivation of the Friedmann equations, discusses the primordial nucleosynthesis, the link with particle physics, the implications for the existence of dark matter, and explains the problems of the standard model which led to the introduction of inflation. These first four chapters constitute what I would define the basic foundations of extragalactic astronomy and cosmology following a logical and didactic path, starting from our galaxy and arriving at the relativistic description of the universe as a whole.
In the second part of the book, each chapter is instead devoted to a different and specific sub-field, reflecting the most active areas of present research in the domain of extragalactic astronomy and cosmology. The fifth chapter discusses Active Galactic Nuclei, with an historical introduction, a classification of the different types and the unified models and the central engine.
Every important aspect, theoretical and observational, concerning supermassive black holes in the center of galaxies is discussed at some length among others, Eddington luminosity, superluminal motion, reverberation mapping. The sixth chapter is devoted to clusters and groups of galaxies, the galaxy distribution, the luminosity function, the galaxy dynamics and cluster mass, the hot gas component, the Sunyaev-Zeldovich effect, the cluster scaling relations, the weak and strong lensing.
The ninth and tenth chapters come back to galaxy properties: they present the Universe at high redshift with all the zoology of objects, from Lyman—break galaxies to Extremely Red Objects, the cosmic star-formation history and the Madau plot and galaxy evolution, which has been added to this new edition and includes the main themes addressed by current research. For example, together with observational results, the author offers a good introduction to hydrodynamical simulations and semi-analytic models dark matter simulations are presented in chapter 7, devoted to the inhomogeneities in the Universe.

Following the suggestions of some reviewers to the first edition, Schneider has added a few problems at the end of each chapter. I think that this is a welcome addition, even if the number of problems remains limited, five per chapter on average, with the exception of the chapter on cosmological models, with 13 problems, while chapters 9 and 10 have no problem at all.
Problems, even simple ones, allow students to digest the abundant material of the course, and I believe that a larger number would not have been useless, even if it is obvious that teachers can provide them. In any case, students will appreciate that the solutions are given in an appendix at the end of the book.
Extragalactic Astronomy and Cosmology: An Introduction
Two appendixes are devoted to the blackbody radiation and to the properties of the stars. They should help students who did not attend or did not yet complete a specific course on stars and stellar evolution. Skickas inom vardagar. Skickas inom vardagar specialorder. This second edition has been updated and substantially expanded. Starting with the description of our home galaxy, the Milky Way, this cogently written textbook introduces the reader to the astronomy of galaxies, their structure, active galactic nuclei, evolution and large scale distribution in the Universe.
After an extensive and thorough introduction to modern observational and theoretical cosmology, the focus turns to the formation of structures and astronomical objects in the early Universe.

The basics of classical astronomy and stellar astrophysics needed for extragalactic astronomy are provided in the appendix. While this book has grown out of introductory university courses on astronomy and astrophysics and includes a set of problems and solutions, it will not only benefit undergraduate students and lecturers; thanks to the comprehensive coverage of the field, even graduate students and researchers specializing in related fields will appreciate it as a valuable reference work.
