Extended radio galaxies

Nature, 1977
Observations of extended radio sources are interpreted in terms of a picture for radio source evolution involving multiple ejections of ram pressure confined plasmons in which instabilities lead to the formation of turbulent hot spots and to in situ particle acceleration.

Radio Galaxies and Quasars

Annals of the New York Academy of Sciences, 1974
The discrete sources of radio emission were first distinguished from the general background radiation during the 1940’s as a result of their rapid amplitude scintillations ; and initially, it was thought that the scintillations were due to fluctuations in the intrinsic intensity of the discrete sources. Assuming that the dimensions of the sources could

Aligned Radio Galaxies

1991
The discovery of high redshift radio galaxies at z ≤ 4 has unleashed a host of questions about their nature. Many new objects are being found, and their unusual properties are being uncovered. They generally exhibit the “alignment effect”, wherein their highly elongated lumpy morphologies are lined up along the axes of their powerful radio sources ...
