Quasars Can Signpost Supermassive Black Hole Binaries

open access: yesThe Astrophysical Journal
Supermassive black holes (SMBHs) are found in the centers of massive galaxies, and galaxy mergers should eventually lead to SMBH mergers. Quasar activity has long been associated with galaxy mergers, so here we investigate if supermassive black hole ...

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

open access: yesThe 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 ...
