The Early Universe: Facts And Fiction (astronomy And Astrophysics Library)

This fourth edition of Börner's "The Early Universe" is practically a new book, not just an updated version. In particular, to meet the wishes of many readers, it is now organized so as to make it more useful as a textbook. Problem sections are also added. In the center are the connections between particle physics and cosmology: the standard model, some basic implications of quantum field theory, and the questions of structure formation. A special feature of the book is the comparison of theoretical predictions with observations, separating "facts from fiction". Special emphasis is given to the observed anisotropies of the cosmic microwave background and the consequences drawn for cosmology and for the structure formation models. Nuclear and particle physicists and astrophysicists, researchers and teachers as well as graduate students will welcome this new edition of a classic text and reference. In this corrected reprint first year results from WMAP have been added to take account of recent developments. Connections developed in recent years between particle physics and cosmologyare the focus of attention in this new textbook. The author describes some of the theories which have been developed to describe the fundamental interaction of elementary particles in the extremely high temperatures of the early universe, taking care to distinguish facts and well-established results from hypotheses and speculations. - The three parts of the book discuss the standard hot big bang model of the earlyuniverse, the basic ideas of the standard and the grand unified theories of elementary particles, and the influence of dark matter on the large-scale evolution of structure. In addition to making some minorcorrections the author has added an appendix presenting new results and an updated bibliography. Two main groups of readers are addressed: research students in astronomy can use this book to understand the impact of elementary particle theory on cosmology, while research students in particle physics can use it to acquaint themselves with the basic facts of cosmology. The book is written carefully enough to appeal also to a wider audience of physicists. Fourteen years is a long time, and especially in the field of cosmology new observational results and new theoretical ideas seem to appear at a steadily increasing rate. It is achallenge to try to review the current status, to give a reasonably fair account of new developments, and not to increase the size of the book out of all proportion. So this fourth edition is practically a new book, with many chapters and sections newly written, not just updated. I have kept the original layout of the book with three parts concerned with (I) the standard model, (II) some basic implications of quantum field theory, and (III) quest ions of structure formation. I have given special emphasis to the new observations of the anisotropies of the cosmic microwave background, and attempted to explain their importance for cosmology as well as for structure formation models. There have also been improved measurements in almost every cosmologically relevant field, from the Rubble constant to element abundances and galaxy distribution statistics. Quite surprisingly, the standard cosmological models can still accommodate all these new obser­ vations.

This fourth edition of Börner's "The Early Universe" is practically a new book, not just updated version. In particular, it is now organized so as to make it more useful as a textbook. And problem sections are also added. In the centre are the connections between particle physics and cosmology: The standard model, some basic implications of quantum field theory and the questions of structure formation. Special emphasis is given to the observed anisotropies of the cosmic microwave background and the consequences drawn for cosmology and for the structure formation models. Nuclear and particle physicists and astrophysicists, researchers and teachers as well as graduate students will welcome this new edition of a classic text and reference.

Before the observational evidence is presented in detail it would be convenient to establish a few theoretical concepts.
