Abstract:

The work deals with quasi-stellar objects as cosmologically distant entities, in accord with the currently accepted interpretation of their redshifts. It has been attempted to understand the physical properties of these objects within the basic framework of the galactic-flare model of Sturrock, which was originally developed in connection with a theory for the major explosions associated with quasars and radio galaxies. The primary aim of the work has been to explain the enormous luminosities, especially in the infrared, that must be produced by cosmologically distant quasars and certain active galaxies. The resultant explanation turns out to be successful not only in this respect but also in leading to a satisfactory model encompassing a number of other aspects of the quasar phenomenon. A specific model for the quasar archetype 3C 273B is discussed quantitatively. It is shown that the physical characteristics of the line-emission region and of the meter-wave radio region are consistent with those adopted for the source of strong infrared continuum radiation. Suggestions are made for possible observations that could help to verify the proposed model. Author
