TL;DR: In this article, the authors observed minute-scale variability suggests a very compact emission region at hundreds of Schwarzschild radii from the central engine in conical jet models, where a minimum bulk jet Lorentz factor of 35 is necessary to avoid both internal gamma-ray absorption and super-Eddington jet power.
