Correlated radiation parameters of quasars and Seyfert nuclei, and the synchro-Compton reactor

The synchro-Compton reactor theory for the continua of quasars and active galactic nuclei predicts that the spectral index of the Compton-scattered radiation should depend on bolometric luminosity as ..cap alpha../sub 0/ = (1--2)L/sub bol//L/sub H/, where L/sub H/ is the luminosity associated with the magnetic energy density. This relation is tested statistically against the nonthermal spectra observed in 48 quasars and Seyfert nuclei, corrections being applied for cosmological redshift, galactic extinction, and the stellar background in the galaxies themselves. Several correlations are obtained; in particular, ..cap alpha../sub 0/ = 19.45-0.42 log L/sub bol/. These would be compatible with synchro-Compton theory if the magnetic field strength, emission-zone radius, and mass are related by H = ((10/sup 14/ cm)/R)(M/M/sub sun/)/sup 1/2/ gauss. A magnetoid: a high-entropy, supermassive oblique rotator: is a promising model for quasars.
