THE FORMATION OF UNIVERSAL SPECTRUM OF RELATIVISTIC ELECTRONS IN ACTIVE GALAXIES AND QUASARS

Abstract

Observations indicate the versatility of radiospectra of active galaxies and quasars. Thus, the spectral indices of radio emission from them lie within 1.3>a>0.6, at an average value of a being equal to 0.8 with a dispersion of 0.15. (Intensity of radiation is I(v) ~ v^-α.) Based on the synchrotron nature of radio emission, we can speak about a universal distribution of electrons with respect to energies N(E) ~ E^-γ, where γ = 2α + 1 = 2.6 with a dispersion of 0.3. Bearing in mind the scale invariance of the electromagnetic interaction of relativistic electrons, the radio-emitting area of quasars and active galaxies can be thought of as a fractal. Using the theory of fractals, it is shown that these celestial bodies should produce a universal distribution of relativistic electrons with γ =2.4. Thus, the universality in the distribution of electrons with respect to energies and emission on frequencies is associated with the fractal nature of the field of radio emission of quasars and active galaxies
