Extragalactic Radio Sources

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 ...

Extragalactic Variable Radio Sources

Nature, 1970
Clues to the origin of the enormously energetic activity in quasars and galactic nuclei may come from observations of the varying radio emission from several objects outside the Galaxy. The varying signals from these objects often seem to come from areas which are only a few light months in diameter.

Extragalactic Radio Sources

1995
Twelve years after the publication of the first results obtained by Jansky in 1932, which marked the beginning of radio astronomy, Reber observed a radio-emission maximum in the constellation Cygnus. It was the first detection of Cygnus A, one of the brightest of all extragalactic sources (that is, located outside our Galaxy) in the radio region. These

Numerical Models of Extragalactic Radio Sources

Science, 1991
Numerical 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.
