Book Synopsis The Physics of Extragalactic Radio Sources by : David De Young
Download or read book The Physics of Extragalactic Radio Sources written by David De Young and published by University of Chicago Press. This book was released on 2002 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Parsec-Scale Radio Jets by : J. Anton Zensus
Download or read book Parsec-Scale Radio Jets written by J. Anton Zensus and published by Cambridge University Press. This book was released on 1990-08-16 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quasars and active galaxies are the most powerful emitters of radiation in the universe. Modern radio telescope arrays have shown that the ultimate energy source resides in the central few parsecs of the galactic nucleus, and powers the emitting regions by way of two oppositely-directed relativistic jets of energy. This volume presents the latest observations and theories of these remarkable objects. Topics discussed include superluminal motions, the physics of jets and shock fronts in jets, related optical observations, and cosmic evolution. Particular attention is given to the "unified theories," which attempt to show that many of the phenomena in powerful extragalactic objects are different aspects of a single, basic mechanism; the main difference in their appearance is a result of their different orientation with respect to the observer.
Book Synopsis Extragalactic Radio Sources by : R. Ekers
Download or read book Extragalactic Radio Sources written by R. Ekers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Beams and Jets in Astrophysics by : Philip A. Hughes
Download or read book Beams and Jets in Astrophysics written by Philip A. Hughes and published by Cambridge University Press. This book was released on 1991-01-25 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first to provide students and researchers in the field of astrophysical jets with a comprehensive and up-to-date account of current research. An important feature of the book is that it combines discussions of both extragalactic and Galactic jets. There are ten chapters, authored by fourteen active researchers, each of whom is an expert on their chosen topic, and the book has been edited to provide a cohesive account of this field of study. This is the first volume to integrate studies of jets on all length scales. It will be an important textbook for graduate students, and a valuable reference source for researchers in many areas of extragalactic and Galactic astronomy. It will also be of interest to plasma physicists and space scientists.

Book Synopsis Extragalactic Radio Sources by : D.S. Heeschen
Download or read book Extragalactic Radio Sources written by D.S. Heeschen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Hot Spots in Extragalactic Radio Sources by : Klaus Meisenheimer
Download or read book Hot Spots in Extragalactic Radio Sources written by Klaus Meisenheimer and published by Springer. This book was released on 2014-03-12 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers presents a rather complete review of current knowledge of hot spots in some strong extragalactic radio sources. An overview of known results along with new data on radio observations and optical observations is given in the first and second parts of the book. Recent computational techniques which allow modelling and simulations of hot spots and jet behaviour are presented in the third part. The fourth part discusses particle acceleration and shock front phenomena. The articles will help the reader to appreciate the role hot spots play as laboratories for studying the interaction of jets with the surrounding medium and for testing our understanding of the overall source dynamics. The book is a valuable complement to the existing literature and an excellent introduction to this fairly new field of research.
Book Synopsis Astrophysical Jets and Their Engines by : Wolfgang Kundt
Download or read book Astrophysical Jets and Their Engines written by Wolfgang Kundt and published by Springer Science & Business Media. This book was released on 1987-07-31 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the documentation of the first Course on 'Neutron Stars, Active Galactic Nuclei and Jets', of an Erice School with a wide astro physical scope. The choice of the subject was made because of an apparent similari ty - stressed already at earlier meetings - of four classes of astrophy sical jet sources: Active Galactic Nuclei, Young Stellar Objects, Binary Neutron Stars and Binary White Dwarfs. They share important properties such as their morphology, high variability and large veloci ty gradients as well as - with some inference - their broad spectrum, hypersonic outflow and core/lobe power ratio. Despite this apparent similarity of the four source classes, quite different models have been put forward for their description: (i) The central engine of active galactic nuclei has been generally thought to be a black hole, in contrast to the central engine of young stellar objects and cometary nebulae which apparently is a pre-T-Tauri star, some six orders of magnitude less compact, and to the central engine of planetary nebulae which mayor may not be a binary white dwarf. (ii) The elongated lobes, or flow patterns, have been often interpreted as highly directional stellar wind outflows whereas in a few well mapped cases, the elongated flow appears to be 'pumped up' through a much narrower channel, or jet, both in the extragalactic and stellar sources.

Rector and published by . This book was released on 2008 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
