Magnetic field strength constraints on $\gamma$-ray flaring regions in the flat spectrum radio quasar PKS 1222+216

Yeji Jo, Sang-Sung Lee

We present a multi-wavelength study of the Flat Spectrum Radio Quasar PKS 1222+216, analyzing its long-term variability of radio data obtained in 2013-2020 from the iMOGABA, MOJAVE…
