Book Description
A concise introduction to cosmology and how light first emerged in the universe 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

Book Description
Star-formation is one of the key processes that shape the current state and evolution of galaxies. This volume provides a comprehensive presentation of the different methods used to measure the intensity of recent or on-going star-forming activity in galaxies, discussing their advantages and complications in detail. It includes a thorough overview of the theoretical underpinnings of star-formation rate indicators, including topics such as stellar evolution and stellar spectra, the stellar initial mass function, and the physical conditions in the interstellar medium. The authors bring together in one place detailed and comparative discussions of traditional and new star-formation rate indicators, star-formation rate measurements in different spatial scales, and comparisons of star-formation rate indicators probing different stellar populations, along with the corresponding theoretical background. This is a useful reference for students and researchers working in the field of extragalactic astrophysics and studying star-formation in local and higher-redshift galaxies.

Book Description
This is the thrilling and romantic sequel to Defy the Stars from the New York Times bestselling author of Star Wars: Lost Stars and Bloodline. An outcast from her home -- Shunned after a trip through the galaxy with Abel, the most advanced cybernetic man ever created, Noemi Vidal dreams of traveling through the stars one more time. And when a deadly plague arrives on Genesis, Noemi gets her chance. As the only soldier to have ever left the planet, it will be up to her to save its people...if only she wasn't flying straight into a trap. A fugitive from his fate -- On the run to avoid his depraved creator's clutches, Abel believes he's said good-bye to Noemi for the last time. After all, the entire universe stands between them...or so he thinks. When word reaches him of Noemi's capture by the very person he's trying to escape, Abel knows he must go to her, no matter the cost. But capturing Noemi was only part of Burton Mansfield's master plan. In a race against time, Abel and Noemi will come together once more to discover a secret that could save the known worlds, or destroy them all. In this thrilling and romantic sequel to Defy the Stars, bestselling author Claudia Gray asks us all to consider where--and with whom--we truly belong.

Book Description
2022 Winner - CHOICE Outstanding Academic Title The determination of stellar ages has been - and still is - crucial for the development of our understanding of the universe, and to constrain theoretical models for the formation of galaxies and the evolution of planetary systems. Stellar ages provide scientists with timescales, and these timescales allow us to identify the relevant physical processes responsible for the development of cosmic structures. This book describes in a simple, yet rigorous, manner the vast array of techniques that have been developed and are currently being used to determine the ages of stars. It also explores how stellar ages inform our knowledge about planets, star clusters, galaxies, even distant galaxies that we cannot resolve into individual stars. Up-to-date with the latest research and technologies in the field, it includes the cutting-edge methods being used based on asteroseismology and discusses open problems that remain to be pondered in future research. It will be of interest to advanced undergraduates and graduate students studying astronomy, in addition to the general public. Key Features Presents an entertaining and accessible approach whilst also providing a rigorous and comprehensive presentation of the subject Describes how to unveil the ages of stellar populations in distant galaxies that we cannot resolve into individual stars Contains historical notes about these techniques, outstanding major problems, and a discussion on future developments in the field

Book Description
The untold story of the religious figures, philosophers, astronomers, geologists, physicists, and mathematicians who, for more than four hundred years, have pursued the answer to a fundamental question at the intersection of science and religion: When did the universe begin? The moment of the universe's conception is one of science's Holy Grails, investigated by some of the most brilliant and inquisitive minds across the ages. Few were more committed than Bishop James Ussher, who lost his sight during the fifty years it took him to compose his Annals of all known history, now famous only for one date: 4004 b.c. Ussher's date for the creation of the world was spectacularly inaccurate, but that didn't stop it from being so widely accepted that it was printed in early twentieth-century Bibles. As writer and documentary filmmaker Martin Gorst vividly illustrates in this captivating, character-driven narrative, theology let Ussher down just as it had thwarted Theophilus of Antioch and many before him. Geology was next to fail the test of time. In the eighteenth century, naturalist Comte de Buffon, working out the rate at which the earth was supposed to have cooled, came up with an age of 74,832 years, even though he suspected this was far too low. Biology then had a go in the hands of fossil hunter Johann Scheuchzer, who alleged to have found a specimen of a man drowned at the time of Noah's flood. Regrettably it was only the imprint of a large salamander. And so science inched forward via Darwinism, thermodynamics, radioactivity, and, most recently, the astronomers at the controls of the Hubble space telescope, who put the beginning of time at 13.4 billion years ago (give or take a billion). Taking the reader into the laboratories and salons of scholars and scientists, visionaries and eccentrics, Measuring Eternity is an engagingly written account of an epic, often quixotic quest, of how individuals who dedicated their lives to solving an enduring mystery advanced our knowledge of the universe.

Book Description
As our nearest star, the Sun offers a unique opportunity to study stellar physics in action. Following the success of his previous books, Galaxies and The Stars, Roger Tayler presents the first full picture of how studies of the Sun and the solar system help us understand stars in general and other planetary systems. Using mathematics appropriate for advanced undergraduate students in physics, this textbook provides a broad and wide-ranging introduction to the Sun as a star. Succinct derivations of key results - such as the properties of spectral lines, the theory of stellar oscillations, plasma physics, magnetohydrodynamics and dynamo theory - are provided in a number of handy appendices, ensuring that the book is completely self contained. Altogether, this is an invaluable textbook for students studying the Sun, stars, the solar-terrestrial environment and the formation of planetary systems.
