Stars are the main factories of element production in the universe through a suite of complex and intertwined physical processes. Such stellar alchemy is driven by multiple nuclear interactions that through eons have transformed the pristine, metal-poor ashes leftover by the Big Bang into a cosmos with 100 distinct chemical species.

As evidenced by five Nobel Prizes in physics, radio astronomy in its 80-year history has contributed greatly to our understanding of the universe. Yet for too long, there has been no suitable textbook on radio astronomy for undergraduate students. Fundamentals of Radio Astronomy: Observational Methods is the first undergraduate-level textbook exclusively devoted to radio astronomy telescopes and observation methods. This book, the first of two volumes, explains the instrumentation and techniques needed to make successful observations in radio astronomy. With examples interspersed throughout and problems at the end of each chapter, it prepares students to contribute to a radio astronomy research team. Requiring no prior knowledge of astronomy, the text begins with a review of pertinent astronomy basics. It then discusses radiation physics, the collection and detection of astronomical radio signals using radio telescopes, the functioning of various components of radio telescopes, and the processes involved in making successful radio observations. The book also provides a conceptual understanding of the fundamental principles of aperture synthesis and a more advanced undergraduate-level discussion of real-world interferometry observations. Web Resource A set of laboratory exercises is available for download on the book’s CRC Press web page. These labs use the Small Radio Telescope (SRT) and the Very Small Radio Telescope (VSRT) developed for educational use by MIT’s Haystack Observatory. The web page also includes a Java package that demonstrates the principles of Fourier transforms, which are needed for the analysis of interferometric data.

Modern cosmology has changed significantly over the years, from the discovery to the precision measurement era. The data now available provide a wealth of information, mostly consistent with a model where dark matter and dark energy are in a rough proportion of 3:7. The time is right for a fresh new textbook which captures the state-of-the art in cosmology. Written by one of the world's leading cosmologists, this brand new, thoroughly class-tested textbook provides graduate and undergraduate students with coverage of the very latest developments and experimental results in the field. Prof. Nicola Vittorio shows what is meant by precision cosmology, from both theoretical and observational perspectives. This book is divided into three main parts: Part I provides a pedagogical, but rigorous, general relativity-based discussion of cosmological models, showing the evidence for dark energy, the constraints from primordial nucleosynthesis and the need for inflation Part II introduces density fluctuations and their statistical description, discussing different theoretical scenarios, such as CDM, as well as observations Part III introduces the general relativity approach to structure formation and discusses the physics behind the CMB temperature and polarization pattern of the microwave sky Carefully adapted from the course taught by Prof. Vittorio at the University of Rome Tor Vergata, this book will be an ideal companion for advanced students undertaking a course in cosmology. Features: Incorporates the latest experimental results, at a time of rapid change in this field, with balanced coverage of both theoretical and experimental perspectives Each chapter is accompanied by problems, with detailed solutions The basics of tensor calculus and GR are given in the appendices

This book investigates the question of how matter has evolved since its origin in the Big Bang, from the cosmological synthesis of hydrogen and helium to the generation of the complex set of nuclei that comprise our world and our selves. A central theme is the evolution of gravitationally contained thermonuclear reactors, otherwise known as stars. Our current understanding is presented systematically and quantitatively, by combining simple analytic models with new state-of-the-art computer simulations. The narrative begins with the clues (primarily the solar system abundance pattern), the constraining physics (primarily nuclear and particle physics), and the thermonuclear burning in the Big Bang itself. It continues with a step-by-step description of how stars evolve by nuclear reactions, a critical investigation of supernova explosion mechanisms and the formation of neutron stars and of black holes, and an analysis of how such explosions appear to astronomers (illustrated by comparison with recent observations). It concludes with a synthesis of these ideas for galactic evolution, with implications for nucleosynthesis in the first generation of stars and for the solar system abundance pattern. Emphasis is given to questions that remain open, and to active research areas that bridge the disciplines of astronomy, cosmochemistry, physics, and planetary and space science. Extensive references are given.

"These are the proceedings of the 2007 Frank N. Bash Symposium, held at the University of Texas at Austin, USA, from October 14-16, 2007. The first "BashFest" was held in 2003 in honor of Professor Frank Bash at his retirement. Since then, the symposium has evolved into a bi-annual event featuring exclusively the research of young astronomers and astrophysicists from around the world." "The symposium centered around invited review talks by thirteen postdoctoral researchers covering the vast range of modern astronomical research, from the dynamics of small bodies in the Solar System, to globular clusters in the Milky Way and neighboring galaxies, to theories and observations of galaxy formation in the early Universe, and the instruments being designed for the thirty-meter class telescopes that will be used to study these diverse fields. Poster contributions from undergraduate and graduate students as well as postdoctoral researchers rounded out the conference. These posters also covered a wide variety of topics, including abundances in metal-rich and metal-poor stars, galaxy formation and evolution, multi-wavelength observations, and theoretical studies of supernovae and the early Universe." "These proceedings are suitable for young and experienced researchers alike who wish to view a snapshot of a wide range of astronomical topics as seen through the eyes of emerging scientists and framed by their vision of the future of the science of astronomy."--BOOK JACKET.

"Dies ist kein Lehrbuch der theoretischen Physik, auch kein Kompendium der Physikgeschichte ... , vielmehr eine recht anspruchsvolle Sammlung historischer Miniaturen zur Vergangenheit der theoretischen Physik - ihrer "Sternstunden", wenn man so will. Frei vom Zwang, etwas Erschöpfendes vorlegen zu müssen, gelingt dem Autor etwas Seltenes: einen "lebendigen" Zugang zum Ideengebäude der modernen Physik freizulegen, ... zu zeigen, wie Physik in praxi entsteht... Als Vehikel seiner Absichten dienen dem Autor geschichtliche Fallstudien, insgesamt sieben an der Zahl. Aus ihnen extrahiert er das seiner Meinung nach Lehrhafte, dabei bestrebt, mathematische Anachronismen womöglich zu vermeiden... Als Student hätte ich mir diese gescheiten Essays zum Werden unserer heutigen physikalischen Weltsicht gewünscht. Sie sind originell, didaktisch klug und genieren sich auch nicht, von der Faszination zu sprechen, die ... von der Physik ausgeht. Unnötig darauf hinzuweisen, das sie ein gründliches "konventionelles" Studium weder ersetzen wollen noch können, sie vermögen aber, dazu zu ermuntern." #Astronomische Nachrichten (zur englischen Ausgabe)#1

Jahrtausendelang war für uns Menschen das eigene Universum so unbegreiflich, dass der Gedanke an andere Welten unvorstellbar war. Erst die moderne Physik mit der Theorie der Multiversen schuf die Voraussetzung, andere, neue Universen zu beschreiben, wie sie nach den Gesetzen der Physik möglich sind. John Barrow zeigt uns die bislang entdeckten Lösungen für Einsteins Universumsgleichung in diesem faszinierenden Buch: rotierende und unberechenbare, sich aufblähende und schrumpfende, heiße und kalte, bucklige und glatte, flache Universen und solche mit einem Loch in der Mitte, Universen voller Leben und Universen, die plötzlich aufhören zu existieren. Eine spektakuläre Reise in die fantastischen Welten der modernen Kosmologie – und an die Grenzen unseres eigenen Vorstellungsvermögens.
