Radio Galaxies and Their Environment
2002In 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

Cosmological Evolution in Radio Galaxies
Nature, 1971ROWAN-ROBINSON has presented evidence that radio galaxies exhibit remarkably strong evolutionary effects with cosmological epoch1. Examination of his evidence, however, indicates that, although an evolutionary effect may indeed be present, no reliable estimate of the time scale involved can yet be made in the way he proposes.

Radio Emission from Galaxies: Exploding Galaxies
1969Besides the well-known “optical window” from the ozone limit at about 3000 A to the infrared at about 22 μ the Earth’s atmosphere has a second range of transparency from λ ≈ 1 millimetre to as far as the onset of ionospheric reflexion at λ ≈ 30 metres. Since K. G. Jansky’s discovery (1931) radio astronomy has exploited this spectral range.
