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.

Klappentext

Cosmology, the attempt to understand the nature and history of the universe and all it contains, is the largest and broadest conceivable subject in science. Over the last decade, cosmology has emerged as a mature science. Theories of the universe are now well developed, and there is more data than ever before. Therefore, many of the old cosmology books are obsolete.Twenty years ago, theorists and observers agreed that the early universe was basically smooth, but they could not agree on how the clumps (inhomogeneities), such as galaxies, emerge from this smoothness (anisotropies). Today scientists agree that the deviations from smoothness -- anisotropies and inhomogeneities -- can be both measured observationally and understood theoretically. It is these deviations to which Modern Cosmology, and indeed much of cosmological research, is devoted.

Zusammenfassung
Explains 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. This book provides foundations, calculations, and interpretations which illuminate the thinking in cosmology.
