One of the most vigorous sciences of our time, astrophysics constantly changes under the impact of new discoveries about everything from our own sun to the most distant and exotic of extragalactic phenomena. In chapters written especially for this volume, twelve distinguished scientists actively pursuing astrophysical research offer up-to-date reviews and commentary on new developments in their fields. With a little grounding in astronomy or physics, the reader will find this book an invaluable source of basic information on the most recent work in this field. Frontiers of Astrophysics can be used as classroom reading, either as a main text or as supplementary reading in astronomy or physics courses, and it can be read with profit by anyone who wants current knowledge presented without complex mathematical arguments. Published within months after the contributions were written, this book is the most convenient and contemporary source on these topics: formation of the solar system (W.R. Ward); new developments in solar research (R. W. Noyes); early phases of stellar evolution (S.E. Storm); endpoints of stellar evolution (A.G.W. Cameron); neutron stars, black holes and supernocvae (H. Gursky); infrared astronomy (G.G. Fazio); gaseous nebulae and their interstellar environment (E.K. Chaisson); chemistry of the interstellar medium (A. Dalgarno); radio observations of galactic masers (J.M. Moran): active galaxies (K. Brecher); galaxies and cosmology (M. Davis); the mass of the universe and intergalactic matter (G.B. Field).

Astronomy is by nature an interdisciplinary activity: it involves mathematics, physics, chemistry and biology. Astronomers use (and often develop) the latest technology, the fastest computers and the most refined software. In this book twenty-two leading scientists from nine countries talk about how astronomy interacts with these other sciences. They describe modern instruments used in astronomy and the relations between astronomy and technology, industry, politics and philosophy. They also discuss what it means to be an astronomer, the history of astronomy, and the place of astronomy in society today.

"In celebration of its 50th anniversary, the NRAO hosted a science symposium highlighting the most important questions that can be addressed by astronomers. The universe is a unique laboratory yielding historical data on the creation of the universe, the formation of the first stars and galaxies, the production of the elements, the assembly of molecules and the building blocks of life in interstellar space, how and where planets form, and possible changes in fundamental physical constants on cosmological time scales. This "laboratory" contains black holes, neutron stars, and gravitational radiation for studying extreme gravity and extremely dense matter. It is filled with the mysterious dark energy and dark matter that control the expansion and destiny of the universe, and whose nature is a critical unsolved problem for physics. This symposium brought together leading scientists to address the most important questions in these areas, the major contributions to astronomy enabled by NRAO instruments-past, present, and future - and to suggest future directions for research involving radio observations and techniques."--BOOK JACKET.

The twentieth century has witnessed the transformation of astronomy from celestial mechanics to astrophysics. While optical telescopes may have presented a peek into the structure of the constituents of the universe, such as stars and galaxies, new windows of observation have revealed far more amorphous objects, from nebulae and sheets to filaments and voids, whose "violent" processes include flares, shocks, accretion disks and jets. In these processes, plasma is often the constituent matter-- as well as the medium through which the astrophysical setting becomes so violent. In this graduate level text, Tajima and Shibata offer a new synthesis starting where classic works on plasma physics left off. Beginning with a view of plasma astrophysics through fundamental processes of quasi-magnetostatic equilibria, quasi-hydrostatic equilibria, and non-equilibria, the authors go on to develop unique approaches to violent astrophysical plasmas-- as opposed to the more quiescent laboratory variety-- and their processes. The text continues with an exploration of the fundamental processes in hydrostatic, magnetostatic, and gravitational objects. The final chapter is devoted to a discussion of the applications of plasma astrophysics to cosmology, anticipating future developments in this exciting field.This text will be of enormous use to graduate-- and some advanced undergraduate-- students, as well as to physicists entering the field of plasma physics.

In the world of physics, very little in the universe is what it first appears to be. And science fiction has imagined some pretty wild ideas about how the universe could work – from hidden extra dimensions in Interstellar to life as a mental projection in The Matrix. But these imaginings seem downright tame compared with the mind-bending science now coming out of physics and astronomy, and in this eBook, Physics: New Frontiers, we look at the strange and fascinating discoveries shaping (and reshaping) the field today. In the world of astrophysics, the weirdness begins at the moment of creation. In “The Black Hole at the Beginning of Time,” the authors discuss theories of what might have come before the big bang. Could our 3-D universe have sprung from the formation of a black hole in a 4-D cosmos? The math says: maybe. Later, in “The Giant Bubbles of the Milky Way,” the authors describe massive structures dubbed “Fermi bubbles” at its center – structures that no one noticed until recently. Technological innovations make much of this new science possible, as we see again in “Neutrinos at the Ends of the Earth,” where 5,000-odd sensors frozen deep within a cubic kilometer of ice in Antarctica aim to catch neutrinos in order to study distant cosmic phenomena. Scientists are also dissecting molecules with the most powerful x-ray laser in the world, as explored in “The Ultimate X-ray Machine.” Even our most fundamental notions of what reality is are up for debate, as examined in “Does the Multiverse Really Exist?” and the aptly named “What Is Real?” in which the authors question whether particles are indeed material things at all. While all of this abstraction might seem like a fun exercise in mental gymnastics, living things must also abide by the laws of physics, which, according to “The Limits of Intelligence,” may prevent our brains from evolving further. Then again, as we’ve learned, things could be different than they appear...

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

The Olympia conference Frontiers of Fundamental Physics was a gathering of about hundred scientists who carryon their research in conceptually important areas of physical science (they do "fundamental physics"). Most of them were physicists, but also historians and philosophers of science were well represented. An important fraction of the participants could be considered "heretical" because they disagreed with the validity of one or several fundamental assumptions of modern physics. Common to all participants was an excellent scientific level coupled with a remarkable intellectual honesty: we are proud to present to the readers this certainly unique book. Alternative ways of considering fundamental matters should of course be vitally important for the progress of science, unless one wanted to admit that physics at the end of the XXth century has already obtained the final truth, a very unlikely possibility even if one accepted the doubtful idea of the existence of a "final" truth. The merits of the Olympia conference should therefore not be judged a priori in a positive or in a negative way depending on one's refusal or acceptance, respectively, but considered after reading the actual of basic principles of contemporary science, new proposals and evidences there presented. They seem very important to us.
