Revisiting Radio Variability of the Blazar 3C 454.3

Revisiting Radio Variability of the Blazar 3C 454.3

We examine lengthy radio light curves of the flat spectrum radio galaxy 3C 454.3 for possible quasiperiodic oscillations (QPOs). The data used in this work were collected at five radio frequencies, 4.8, 8.0, 14.5, 22.0, and 37.0 GHz between 1979 and 2013 as observed at the University of Michigan Rad...
