The existence of jets emanating from the central sources of radio galaxies and quasars was perhaps the most important discovery for our understanding of the nature of active galactic nuclei. These proceedings present reviews and research papers on extragalactic radio sources. The book begins witha discussion of the phenomenology and models of radio sources. The main partis devoted to detailed studies of jets by VLBI, to the information obtained about the structure of the central source as deduced from variability studies, to production, confinement and velocity of jets as well as to numerical simulations of the jet phenomenon. Reviews of the two best studied jets - those in the radio galaxy M87 and the quasar 3C273 - illustrate our current observational picture of extragalactic radio jets in all accessible wavelength ranges. A section on the influence of the environment on radio galaxies concludes the book. This topical volume addresses researchers and graduate students in astrophysics.

"These proceedings of an international meeting held May 2007 in Girdwood, Alaska, USA provide a comprehensive overview of recent theoretical and observational work on the nature of extragalactic jets, from parsec to kiloparsec scales. Special emphasis is given to the interaction of jets with their environment and to the insights this interaction can provide. The invited reviews, contributed talks, and poster sessions form a detailed summary of the latest findings, as well as illustrate outstanding questions that remain to be resolved. This book is suitable for researchers and graduate students. The origin and evolution of highly collimated and highly energetic outflows from the nuclei of some galaxies remains, after over 30 years of intensive study, and enigmatic process. We still do not know how these jets are collimated, or what they contain beyond relativistic particles and magnetic fields, much less how they come to be in the first place. If we could unravel the mystery of their origins, then it is clear that new and significant constraints could also be placed on the origin and evolution of the "central engine," presumably a massive black hole, that creates them. This is turn would give rise to new constraints on the formation and evolution of the parent galaxies and their environment. The quest for insights into the nature of these objects has always been made difficult by the last of information conveyed by their simple power law radiation spectrum, and so much of the information gained must be inferential. However, the hope remains that by gaining an understanding of the interaction of these objects with their environment we may be able to deduce the key parameters of the jets themselves. This strategy of working from "the outside in" is showing increasing promise as higher resolution observations with increasing sensitivity are being made over increased coverage in wavelength, especially as these are cast against results from sophisticated theoretical calculations that include three-dimensional MHD simulations."--Publisher's website

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.
