Spectral Energy Distribution Variability of the Blazar OJ 287 During 2009–2021

Spectral Energy Distribution Variability of the Blazar OJ 287 During 2009–2021

Using nearly simultaneous radio, near-infrared, optical, and ultraviolet (UV) data collected since 2009, we constructed 106 spectral energy distributions (SEDs) of the blazar OJ 287. These SEDs are well fitted by a log-parabolic model. By classifying the data into “flare” and “quiescent” segments, w...
