Book Description
IAU Symposium 97, Extragalactic Radio Sources, was held at Albuquerque, New Mexico August 3-7, 1981. It was co-sponsored by IAU Commissions 28, 40, 47 and 48 and by URSI Commission J. Financial and organizational support were provided by the National Radio Astronomy Observatory, the University of New Mexico, and the National Science Foundation. A wide variety of interesting objects and phenomena can be covered under the heading "Extragalactic Radio Sources", and a diverse set of topics was in fact discussed at the symposium. Radio galaxies, quasars, Seyfert galaxies and BL Lacertids received the most attention, but normal galaxies, the galactic center, and even SS433 were also discussed. While the unifying theme of the symposium was radio emission, studies at all wavelengths--X-ray, UV, optical, IR, and radio--were included. In general, the emphasis was on individual objects and the physical processes associated with them, but there were also papers on statistical studies and cosmology. The symposium was attended by 209 scientists from 18 countries.

Book Description
Galactic and Extragalactic Radio Astronomy is a fundamental text for graduate students and professional astronomers and covers all aspects of radio astronomy beyond the solar system. Each chapter is written by a renowned expert in the field and contains a review of a particular area of radio astronomy and presents the latest observations and interpretations as well as an extensive view of the literature (as of 1988). Topics covered include: galactic continuum emission, HII regions, the diffuse interstellar medium, interstellar molecules, astronomical masers, neutral hydrogen, the galactic center, radio stars, supernova remnants, pulsars, extragalactic hydrogen, radio galaxies and quasars, the microwave background, and cosmological radio sources.

Book Description
The physics of active galactic nuclei, the origin of extragalactic jets and the formation of extended extragalactic radio sources are among the most interesting challenges of modern astrophysics. This book contains the proceedings of the 7th meeting of the Institut d'Astrophysique de Paris, which drew together both theorists and observers in this exciting field. Recent observational data at X-ray, optical and radio wavelengths is discussed, and new theoretical developments concerning beam and jet formation models are considered. Special treatment is given to plasma physics problems related to particle acceleration, magnetic reconnection, beam-plasma interaction and coherent emission. The volume will be of use to all students and researchers who are working in this field.

Book Description
On the 100th anniversary of Marconi's successful experiment on radio broadcasting, 250 astronomers from all over the world met in Bologna (Italy) for five days, to update their knowledge of the physics and statistical properties of powerful extragalactic radio sources. Since their discovery in the fifties enormous progress has been made. The existence of superluminal motions in the cores of radio sources, the presence there of a black hole surrounded by an absorbing dust torus, as inferred mostly from studies at other wavelengths, are now accepted ideas. Nevertheless, in spite of these efforts, there are many questions still unanswered. For instance we do not know which mechanism produces the huge amount of energy supplied to radio sources, how the jets connecting the `engine' to the lobes are formed and collimated, which of the differences observed among the various classes of radio sources are apparent and which are real. These and other related topics are discussed in this book.

Book Description
Extragalactic radio sources are among the most unusual and spectacular objects in the universe, with sizes in excess of millions of light years, radiated energies over ten times those of normal galaxies, and a unique morphology. They reveal some of the most dramatic physical events ever seen and provide essential clues to the basic evolutionary tracks followed by all galaxies and groups of galaxies. In The Physics of Extragalactic Radio Sources, David De Young provides a clearly written overview of what is currently known about these objects. A unique feature of the book is De Young's emphasis on the physical processes associated with extragalactic radio sources: their evolution, their environment, and their use as probes to solve other astrophysical problems. He also makes extensive use of the large amount of data now available from observations at x-ray, optical, and radio wavelengths to illustrate his main points. The Physics of Extragalactic Radio Sources will be a comprehensive introduction to the field for graduate students and a useful summary for astrophysicists.

Book Description
Providing students with an in-depth account of the astrophysics of high energy phenomena in the Universe, the third edition of this well-established textbook is ideal for advanced undergraduate and beginning graduate courses in high energy astrophysics. Building on the concepts and techniques taught in standard undergraduate courses, this textbook provides the astronomical and astrophysical background for students to explore more advanced topics. Special emphasis is given to the underlying physical principles of high energy astrophysics, helping students understand the essential physics. The third edition has been completely rewritten, consolidating the previous editions into one volume. It covers the most recent discoveries in areas such as gamma-ray bursts, ultra-high energy cosmic rays and ultra-high energy gamma rays. The topics have been rearranged and streamlined to make them more applicable to a wide range of different astrophysical problems.
