The formation of galaxies is one of the greatest puzzles in astronomy, the solution is shrouded in the depths of space and time, but has profound implications for the universe we observe today. This book discusses the beginnings of the process from cosmological observations and calculations. It examines the different theories of galaxy formation and shows where each theory either succeeds or fails in explaining what we actually observe. In addition, the book looks ahead to what we may expect to uncover about the epoch of galaxy formation from the new and upcoming generations of telescopes and technology.

The insights of relativity have illuminated a century of astronomical discovery, often going beyond the phenomena that Einstein lived to see. This book shows, in nonmathematical ways, how deeply these ways of viewing the Universe have informed our interpretations of it, and how many of the amazing discoveries of these decades have made sense only as part of Einstein's universe. The author brings together the ways in which we see the bizarre effects of relativity played out on a cosmic scale. None of this is particularly new to practicing astronomers, but much has yet to be seen outside technical journals. The presentation avoids mathematics (except for the most famous equation in all of physics ), and is designed to be accessible to the interested public. Gravitational lenses, the visible effects of light-travel delays, the search for black holes, the ways relativity in atomic nuclei makes stars shine, are all treated.

This is volume 6 of Planets, Stars and Stellar Systems, a six-volume compendium of modern astronomical research, covering subjects of key interest to the main fields of contemporary astronomy. This volume on Extragalactic Astronomy and Cosmology edited by William C. Keel presents accessible review chapters on Galaxy Morphology, Elliptical and Disk Galaxy Structure and Modern Scaling Laws, Star Formation in Galaxies, The Cool ISM in Galaxies, The Influence of Environment on Galaxy Evolution, Clusters of Galaxies, Active Galactic Nuclei, Large Scale Structure of the Universe, Distance Scale of the Universe, Galaxies in the Cosmological Context, Evolution of Active Galactic Nuclei, The Intergalactic Medium, and Cosmic Microwave Background.

All chapters of the handbook were written by practicing professionals. They include sufficient background material and references to the current literature to allow readers to learn enough about a specialty within astronomy, astrophysics and cosmology to get started on their own practical research projects. In the spirit of the series Stars and Stellar Systems published by Chicago University Press in the 1960s and 1970s, each chapter of Planets, Stars and Stellar Systems can stand on its own as a fundamental review of its respective sub-discipline, and each volume can be used as a textbook or recommended reference work for advanced undergraduate or postgraduate courses. Advanced students and professional astronomers in their roles as both lecturers and researchers will welcome Planets, Stars and Stellar Systems as a comprehensive and pedagogical reference work on astronomy, astrophysics and cosmology.

Planets, Stars and Stellar Systems is a compendium of modern astronomical research covering subjects of key interest to the main fields of contemporary astronomy. The six volumes of the set edited by Terry Oswalt (Editor-in-Chief) comprise:

Volume 1: Telescopes and Instrumentation Ian McLean (Ed.)

Volume 2: Astronomical Techniques, Software, and Data Howard E. Bond (Ed.)

Volume 3: Solar and Stellar Planetary Systems Linda French; Paul Kalas (Eds.)

Volume 4: Stellar Structure and Evolution Martin A. Barstow (Ed.)

Volume 5: Stellar Systems and Galactic Structure Gerard Gilmore (Ed.)

Volume 6: Extragalactic Astronomy and Cosmology William C. Keel (Ed.)

Each of the approximately 85 chapters is written by a practicing professional within the appropriate sub-discipline. They include sufficient background material and references to the current literature to allow one to learn enough about a specialty within astronomy, astrophysics and cosmology to get started on a practical research project. In the spirit of the series Stars and Stellar Systems published by Chicago University Press in the 1960s and 1970s each chapter of Planets, Stars and Stellar Systems stands on its own as a fundamental review of its respective sub-discipline and each volume can be used as a text or recommended reference for advanced undergraduate or postgraduate courses. Advanced students through professional astronomers in their roles as both lecturers and researchers will welcome Planets, Stars and Stellar Systems as comprehensive and pedagogical reference to astronomy, astrophysics and cosmology."
