Numerical Models of Extragalactic Radio Sources
Science, 1991Numerical simulations with supercomputers allow analysis of the wide range of nonlinear physics inherent in the hydrodynamic and magnetohydrodynamic equations. When applied to extragalactic radio sources, these numerical models have begun to reproduce many of the complex structures observed on telescopic images.

Theory of extragalactic radio sources
Reviews of Modern Physics, 1984Powerful extragalactic radio sources comprise two extended regions containing magnetic field and synchrotron-emitting relativistic electrons, each linked by a jet to a central compact radio source located in the nucleus of the associated galaxy. These jets are collimated streams of plasma that emerge from the nucleus in opposite directions, along which

Jets in Extragalactic Radio Sources
Science, 1984Observations now require that there be a continuous supply of energy to the giant extragalactic radio sources. These observations also suggest that this energy input may be in the form of streams or jets of gas emanating from the centers of galaxies and quasi-stellar objects. Current data indicate that the large-scale jet structures are not moving with

Extended Extragalactic Radio Sources
Annual Review of Astronomy and Astrophysics, 1976The most important feature of the extended sources is the double structure characterized in an ideal model by two extended radio-emitting regions situated symmetrically about the nucleus of an optical galaxy or QSO, with a characteristic overall size of about 100 kpc. Not all extended radio sources show this double structure. It has been found that at

Rapid variability of extragalactic radio sources
Nature, 1989Since its discovery more than 20 years ago1,2, variability of extragalactic radio sources on timescales of weeks to years has been the subject of many investigations. Little is known, however, about radio variability of extragalactic sources on timescales of less than a few days.

Physics Today, 1973
Radio astronomers have recently begun to harvest a wealth of data using instruments with greatly improved sensitivity and resolution. They are now mapping the internal structure of galaxies and quasars over a wide range of the radio spectrum. Variations in the structure as well as in the intensity of these sources are being observed on time scales ...
