Modern Cosmology

Modern Cosmology, Second Edition, provides a detailed introduction to the field of cosmology. Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaître-Robertson-Walker metric, this trusted resource includes careful treatments of dark energy, big bang nucleosynthesis, recombination, and dark matter. The reader is then introduced to perturbations about an FLRW universe: their evolution with the Einstein-Boltzmann equations, their primordial generation by inflation, and their observational consequences: the acoustic peaks in the CMB; the E/B decomposition in polarization; gravitational lensing of the CMB and large-scale structure; and the BAO standard ruler and redshift-space distortions in galaxy clustering. The Second Edition now also covers nonlinear structure formation including perturbation theory and simulations. The book concludes with a substantially updated chapter on data analysis. Modern Cosmology, Second Edition, shows how modern observations are rapidly revolutionizing our picture of the universe, and supplies readers with all the tools needed to work in cosmology. - Offers a unique and practical approach for learning how to perform cosmological calculations. - New material on theory, simulations, and analysis of nonlinear structure. - Substantial updates on new developments in cosmology since the previous edition.

Scott Dodelson is Head of the Department of Physics at Carnegie Mellon University. He received his Ph.D. from Columbia University and was a research fellow at Harvard before moving to Fermilab, the University of Chicago, and Carnegie Mellon. He is the author of more than 200 papers on cosmology, most of which focus on the cosmic microwave background and the large-scale structure of the universe. Dodelson serves as the co-Chair of the Science Committee of the Dark Energy Survey.
