Product Description

Modern Cosmology begins with an introduction to the smooth, homogeneous universe described by a Friedman-Robertson-Walker metric, including careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter. From this starting point, the reader is introduced to perturbations about an FRW universe: their evolution with the Einstein-Boltzmann equations, their generation by primordial inflation, and their observational consequences. These consequences include the anisotropy spectrum of the cosmic microwave background (CMB) featuring acoustic peaks and polarization, the matter power spectrum with baryonic wiggles, and their detection via photometric galaxy surveys, redshift distortions, cluster abundances, and weak lensing. The book concludes with a long chapter on data analysis.

Modern Cosmology is the first book to explain in detail the structure of the acoustic peaks in the CMB, the E/B decomposition in polarization which may allow for detection of primordial gravity waves, and the modern analysis techniques used on increasingly large cosmological data sets. Readers will gain the tools needed to work in cosmology and learn how modern observations are rapidly revolutionizing our picture of the universe.

Modern Cosmology Review

I stumbled across the title of this book when I was browsing around somebody's cosmology course website. I know that Scott Dodelson is a quite well-known cosmologist, so I start searching for more information. After reading the preliminary detailed table of contents (I found it somewhere on the web) and the book description from Academic Press, I decided to pre-order the book. The book arrived just on March 31. I tried to take a quick but thorough view before write this comment. I haven't read the book in full. Here i would just like to write the Table of Contents in more detail by including the sections.1. The Standard Model and Beyond. The expanding universe, Hubble diagram, Big Bang Nucleosynthesis (BBN), Cosmic Microwave Background (CMB), beyond Standard Model.2. The Smooth, Expanding Universe. General relativity (crash course), distances, evolution of energy, cosmic inventory (photons, baryons, matter, neutrinos, dark energy, epoch of matter-radiation equality).3. Beyond Equilibrium. Boltzmann equation for annihilation, BBN (neutron & light elements abudance), recombination, dark matter.4. The Boltzmann Equations (BE). BE for harmonic oscillator, the collisionless BE for photons (0th and 1st order), collision terms: Compton scattering, BE for photons, BE for Cold Dark Matter (CDM), BE for baryons.5. Einstein Equations. Perturbed Ricci tensor and scalar, two components of Einstein Equations, tensor perturbations, decomposition theorems, gauges.6. Initial conditions. Einstein-Boltzmann equations at early times, the horizon, inflation, gravity wave production, scalar perturbations.7. Inhomogeneities. Prelude, large scales (super-horizon & through horizon crossing), small scales (horizon & sub-horizon crossing), growth function, beyond CDM. 8. Anisotropies. Overview, large-scale anisotropies, acoustic oscillations (tightly coupled), diffusion (Silk) damping, inhomogeneities to anisotropies (free streaming, C____noise___ 1000s), anisotropy spectrum (Sachs-Wolfe, small scales), cosmological parameters.9. Probe of Inhomogeneities. Angular correlation, peculiar velocities, redshift space distortions, galaxy clusters.10. Weak Lensing and Polarization. Gravitational distortion, geodesics and shears, ellipticity, weak lensing power spectrum, polarization, quadrupole and Q/U (or E/B as in recent literatures) decomposition, polarization power spectra, detection of gravity waves.11. Analysis. Likelihood function, signal covariance matrix, Karhunen-Loeve & optimal quadratic, Fisher matrix, mapmaking & inversion, systematics, foregrounds.Appendix A. Solution to Selected Problems
Appendix B. Numbers
Appendix C. Special Functions
Appendix D. Symbols.
Bibliography.In addition, each chapter is ended with a summary and further reading list. Quite nice indeed. The bibliography are extensive: there are classic, pioneering papers, recent papers, textbooks. There are some color plates in the middle part of the book. In my opinion, this book is far better than Peacock in discussing new aspect of anisotropies and inhomogeneities. Lots of topics that were only previously available in research papers, review articles, summer school lectures, preprints, are brought together to the form of a decent book. The chapter of analysis is quite interesting, since the subject has become very demanding but there are still no single treatment of it.Dodelson said in the preface that the expected audience are advanced undergraduate and beginning graduate students. Some of the necessary materials (GR, inflation, are introduced in the text).I myself suggests, however, that the reader should have a proficient knowledge in standard undergraduate physics (mechanics, thermodynamics, electromagnetism, quantum physics), mathematical physics, and general relativity if possible. Some knowledge of astrophysics/astronomy, statistics/data analysis, kinetic theory, would certainly be welcomed.A little bit of cons, however are inevitable. The current development in cosmology is astounding. Just a few weeks before the book was published, the WMAP team released their first result after a year of observations, which put tight constraints for cosmological models. Several numbers and figures in the book then are in the need to be updated. Topics such as distant quasars, cosmic reionization and the end of cosmic dark ages, first-generation stars, might be worthy enough to be included in the future.This book is definitely a must buy for cosmologist.Update 2003 July 8

You should also get two more books beside this.1) Kinetic theory in the expanding universe by Jeremy Bernstein, Cambridge, 1988, ISBN 0-521-36050-1. Best reference material to understand relativistic Boltzmann equation in Dodelson chapter 3-5.2) The Early Universe by Edward W. Kolb and Michael S. Turner, Perseus/Westview, 1994, ISBN 0-201-62674-8. Contains extensive material on FRW metric, detailed discussion on nucleosynthesis and particle physics-cosmology interface, inflation, and structure formation.
