Produktbeschreibung

The existence of jets emanating from the central sources ofradio galaxies and quasars was perhaps the most importantdiscovery for our understanding of the nature of activegalactic nuclei. These proceedings present reviews andresearch papers on extragalactic radio sources. The bookbegins witha discussion of the phenomenology and models ofradio sources. The main partis devoted to detailed studiesof jets by VLBI, to the information obtained about thestructure of the central source as deduced from variabilitystudies, to production, confinement and velocity of jets aswell as to numerical simulations of the jet phenomenon.Reviews of the two best studied jets - those in the radiogalaxy M87 and the quasar 3C273 - illustrate our currentobservational picture of extragalactic radio jets in allaccessible wavelength ranges. A section on the influence ofthe environment on radio galaxies concludes the book. Thistopical volume addresses researchers and graduate studentsin astrophysics.

Autorenporträt

Jets in extragalactic radio sources are among the most interesting objects studied in astrophysics. Improvements in the observational methods, including space telescopes, have significantly furthered both the observational situation and our theoretical understanding. The contributions to this volume report on the status of our present knowledge in a comprehensive survey of this field of research. They address specialists as well as graduate students in astrophysics.
