Morphology of Extragalactic Radio Sources
1976“The astronomical instruments have been in use from very ancient days, handed down from one dynasty to another, and closely guarded by the official astronomers. Scholars have therefore had little opportunity to examine them, and this is the reason why unorthodox cosmological theories were able to spread and flourish.” - Fang, Hsuan-Ling, History of the

Models of Extragalactic Radio Sources
1976In these lectures I shall first review the basic problems of the energy supply to radio components and their containment (cf. Longair, Ryle and Scheuer 1973). Then I want to talk about models in which energy is transferred from the nucleus to the radio components by a relativistic beam (Rees 1971, Blandford and Rees 1974), and about the radio ...

Radio Recombination Lines in Extragalactic Sources
1980Attempts to detect Hydrogen recombination lines from extragalactic sources using narrow 10MHz observing windows began at least as far back as 19T15 when E. Seaquist and I searched for emission lines in 3C273. Other unreported searches with negative results were almost certainly made, but meaningful observations began only in late 1975 when wider ...
