Fig. 1.
γ-ray and radio light curves of 3C 273 in 2015−2019. From top to bottom: ALMA band 3 (∼100 GHz) overlaid on the VLBA 43 GHz total flux, Fermi-LAT fluxes using monthly binning, and Fermi-LAT fluxes using weekly binning. For the γ-ray light curves, the 2 σ upper limits are indicated by red downward arrows. The vertical dashed lines show three γ-ray outbursts that are identified in the weekly light curve. Each of the shaded areas spans 100 days centered at the peak of a γ-ray outburst.
