Follow-up on the Supermassive Black Hole Binary Candidate J1048+7143: Successful Prediction of the Next Gamma-Ray Flare and Refined Binary Parameters in the Framework of the Jet Precession Model

The Astrophysical Journal Letters
Analyzing single-dish and very long baseline interferometry radio, as well as Fermi Large Area Telescope γ -ray observations, we explained the three major flares in the γ -ray light curve of FSRQ J1048+7143 with the spin–orbit precession of the dominant ...
