Variations in the Flux Density of Some Quasi-stellar Sources


Further data on the variations in the 1.96 cm flux density of the quasars 3C 273, 3C 279, 3C 446 and 3C 454.3 are reported. The data support the theory that the variation is produced by repeated injection into magnetic field of clouds of relativistic electrons, which then expand, but some difficulties remain.
