Abraham Loeb – författare

This book provides a comprehensive, self-contained introduction to one of the most exciting frontiers in astrophysics today: the quest to understand how the oldest and most distant galaxies in our universe first formed. Until now, most research on this question has been theoretical, but the next few years will bring about a new generation of large telescopes that promise to supply a flood of data about the infant universe during its first billion years after the big bang. This book bridges the gap between theory and observation. It is an invaluable reference for students and researchers on early galaxies. The First Galaxies in the Universe starts from basic physical principles before moving on to more advanced material. Topics include the gravitational growth of structure, the intergalactic medium, the formation and evolution of the first stars and black holes, feedback and galaxy evolution, reionization, 21-cm cosmology, and more.* Provides a comprehensive introduction to this exciting frontier in astrophysics * Begins from first principles * Covers advanced topics such as the first stars and 21-cm cosmology * Prepares students for research using the next generation of large telescopes * Discusses many open questions to be explored in the coming decade

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

The exploration of the first billion years of the history of the Universe represents one of the great challenges of contemporary astrophysics. This book contains the worked out lectures given at the 36th Saas-Fee Advanced Course "First Light in the Universe" by three eminent scientists in the field: Abraham Loeb, Andrea Ferrara, and Richard Ellis. The formation of the first stars and black holes, the initial mass function, feedback effects, early dust formation, the cosmic star formation history, distant galaxies, cosmic reionisation and the cosmic infrared background are the main topics treated. This book contains an accessible and up-to-date review of the field and will be useful to graduate students of astronomy, cosmologists, physicists and researchers. The topic of this book is particularly timely, as many new important observational facilities are being built, for which "first light in the universe" is one of the main science drivers.
