Radio Galaxies and Quasars [PDF]
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

Radio Galaxies and Their Environment [PDF]
, 2002 In this paper we review the properties of radio galaxies in connection to the effect of the dynamic gaseous environment inside clusters in which they are embedded. The external gas can interact with a radio source in different ways: modifying its morphology via ram-pressure, confining the radio lobes, possibly feeding the active nucleus, enhancing star

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.

Galaxy Interactions and the Radio Galaxy Phenomenon
1990We have been studying powerful radio galaxies (which we define as having radio power at 178MHz, P 178 ≥ 5xl024 Watts/Hz for a cosmology of H o = 100 km sec-1 Mpc-1 and q o = 0) in order to determine their origins. There are two distinct classes of powerful radio galaxies (PRGs), the so called class A and B radio galaxies (Hine and Longair 1979; Heckman

Radio Galaxies and Quasars in Clusters of Galaxies
Publications of the Astronomical Society of Australia, 1983The study of radio galaxies situated within clusters of galaxies has become a broad field, with hundreds of papers published in the last few years. This review will therefore be restricted mainly to consideration of the interactions between the extended components of radio sources in clusters and the diffuse gas (intracluster medium, ICM) which occurs ...

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 ...
