Though astrophysicists have developed a theoretical framework for understanding how the first stars and galaxies formed, only now are we able to begin testing those theories with actual observations of the very distant, early universe. We are entering a new and exciting era of discovery that will advance the frontiers of knowledge, and this book couldn't be more timely. It covers all the basic concepts in cosmology, drawing on insights from an astronomer who has pioneered much of this research over the past two decades.

Abraham Loeb starts from first principles, tracing the theoretical foundations of cosmology and carefully explaining the physics behind them. Topics include the gravitational growth of perturbations in an expanding universe, the abundance and properties of dark matter halos and galaxies, reionization, the observational methods used to detect the earliest galaxies and probe the diffuse gas between them--and much more.

Cosmology seeks to solve the fundamental mystery of our cosmic origins. This book offers a succinct and accessible primer at a time when breathtaking technological advances promise a wealth of new observational data on the first stars and galaxies.Provides a concise introduction to cosmology Covers all the basic concepts Gives an overview of the gravitational growth of perturbations in an expanding universe Explains the process of reionization Describes the observational methods used to detect the earliest galaxies

Winner of the 2012 Chambliss Astronomical Writing Award, American Astronomical Society "[E]ngaging, fast-paced... Loeb's infectious excitement stirs desire to join him in these endeavors... [R]eaders will find How Did the First Stars and Galaxies Form? a lucid introduction to an exciting research field that is set to flourish in the next decades."--Science "Hands up everyone who can answer the question Loeb poses in the title of his small but sprightly book. No, not just the basics: big bang, cosmic inflation, lights, camera, action. Me neither. Harvard University astrophysicist and cosmologist Abraham Loeb can, and he does in this latest installment of the Princeton Frontiers in Physics series. While the book targets potential cosmologists and scientists, general readers will enjoy the non-technical chapters."--Australian "Anyone interested in an introduction to this dramatic story, be they academic or educated nonprofessional, would do well to start with Loeb's book. It contains only the most important equations in the field, and its general level of mathematical sophistication is compatible with introductory courses in calculus or mathematical physics. This small book is a gem belonging to an almost extinct genre: intermediate-level monographs that are both accessible to educated non-specialists in the field and tightly focused on a problem."--Milan M. Cirkovic, American Journal of Physics "Loeb, a leading theoretical cosmologist, has written a lucid account of the relevant physics, beginning with a brief review of cosmological models based on Einstein's general relativity equations."--Choice
