Scientific paper

Current estimates of quasar masses are based on the idea that the objects are outbursts involving galaxies or on the argument that the conversion of mass into radiant energy requires a minimum mass. These estimates are contrasted with those that can be obtained by considering the dynamics of the gas in the regions surrounding the highly compact nonthermal central source. In the analysis, it is assumed that absorption arises in gas clouds associated with quasars and that the emission- and absorption-line regions are being driven by radiation pressure. The results demonstrate that the masses of cosmologically distant quasars must lie between 50 million and 2 billion solar masses and that the mass-loss rate should be about one ten-millionth part per year. If the quasars are local objects, the upper mass limit is reduced to about 20 million solar masses. It is noted that these masses are significantly less than the masses of galaxies, but might be appropriate for galactic nuclei.
