"Unveiling the Cosmic Connection: Evidence of Supermassive Binary Systems in Active Galactic Nuclei"

An international research team has presented evidence that the variability in brightness and jet curvature observed in blazars, accreting supermassive black holes in the centers of galaxies, is likely caused by the precession of the jet source. This precession can be attributed to the presence of a second massive black hole or a warped accretion disk. The study suggests that blazar variability may be of deterministic nature rather than stochastic, and the jet curvature could be a signature of binary black holes. Radio observations using Very Long Baseline Radio Interferometry (VLBI) provide the highest resolution for studying these phenomena.
