Rare X-shaped radio galaxies shaped by supermassive black holes

A team of astrophysicists may have finally solved the mystery of what creates rarely-seen radio-bright X-shaped galaxies.

A sophisticated simulation has shown that these galaxies, which are distinguished by four massive jets of material that shoot into space, could result from a process much simpler than scientists previously thought. The simulation shows that the shape can form from the interaction between hot gas falling into the galaxy’s supermassive black hole and the near light-speed jets of material it blasts out.
