Cameron, A.G.W., 1965: Gas clouds in dense star clusters: A possible quasar model. Nature, 207, no. 5002, 1140-1142, doi:10.1038/2071140a0.
In order to account for the large energy input required by intense extragalactic radio sources, I suggested that the collective formation of a cluster of more massive stars would result in numerous Type II supernova explosions in a limited period of time. Following the discovery of light flashes in the light curve of the quasar 3C 273, S. A. Colgate and I adapted this picture also for quasars, and proposed that the flashes resulted from the enhancement of the light output of the Type II supernovae when their ejected envelopes interacted with circumstellar gas of density about 10-14 g/cm3. Greenstein and Schmidt then published their analysis of the emission lines from 3C 48 and 3C 273, from which they concluded that 3C 273 was a gas cloud of density ∼10-17 g/cm3 and dimensions ∼1 parsec which was held in place by a large unseen mass. It is the purpose of the present article to discuss more extensively the properties of such gas clouds in dense clusters of stars, and to see if the observed properties of quasars are compatible with them. The convention will be adopted that all the visible quasi-stellar objects will be called quasars, and the intense radio-emitting objects will be called radio quasars.
