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 ...

Seldom have astronomers been presented with such an intriguing problem as that of the pulsed radio sources, revealed just over six months ago during a survey made at Cambridge using a new radiotelescope of high sensitivity. The difficulty is to find a satisfactory theory to account for celestial bodies of planetary size which emit flashes of radio ...

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

Abstract This paper describes several modifications to the simplest model of a beam that might have the effect of suppressing the short-wavelength Kelvin–Helmholtz instabilities that can cause jet disruption while maintaining the long-wavelength modes that are popular as causes of distorted jet structure.
