Abstract: | We explore the possibility of determining the corpuscular composition of the plasma in the relativistic jets of blazars and microquasars from data on the polarization and intensity of their radio synchrotron emission. We have constructed a universal diagram that allows the relative content of nonrelativistic electrons to be established in specific objects using information about their frequency spectra and polarization at individual frequencies. As a result, we have found that the electron plasma component in the jets of the blazars 3C 279 and BL Lac is relativistic. In the jets of the microquasar GRS 1915+105, the cold plasma density may be comparable to or considerably higher than the relativistic particle density. |
