X-shaped radio galaxies might form more simply than expected

Using new simulations, astrophysicists implemented simple conditions to model the feeding of a supermassive black hole and the organic formation of its jets and accretion disk. When the researchers ran the simulation, the simple conditions organically and unexpectedly led to the formation of an X-shaped radio galaxy. Surprisingly, the researchers found that the galaxy's characteristic X-shape resulted from the interaction between the jets and the gas falling into the black hole.
