Simulation of X-shaped radio galaxy (VIDEO) Northwestern University This video is under embargo. Please login to access this video.

Gas infall forms an accretion flow (bright red) deep within which we witness the formation of an accretion disk (yellow) that feeds the black hole, that launches a pair of relativistic jets (light blue), which propagate vertically and shock the ambient gas (dark red). The older cavities (dark blue), which were inflated by previous misaligned jet activity, buoyantly rise at an angle to the vertically-propagating jets and form the X-shaped jet morphology.
