One way black holes shape their surroundings is by generating powerful jets of high-energy particles. The jets, which are bright in radio waves, have been seen to push around the hot gas that envelops the galaxy. Enabling astronomers to detect huge cavities and powerful shock fronts in the hot, X-ray emitting gas. The opposite scenario is unfolding in the galaxy 3C442A. X-ray data from Chandra X-ray Observatory and radio observations from the NSF's VLA show that the hot gas (blue) in the middle of 3C442A is pushing apart the radio-bright gas (orange). The inner sections of the radio structure are sharp and concave, which is consistent with the idea that the X-ray bright gas is sweeping the radio-emitting gas aside. This is the first convincing evidence for such a role reversal. There are two galaxies near the middle of 3C442A which are in the process of merging. Energy generated from this impending merger is heating the combined atmospheres is causing them to shine brightly in X-rays and expand. Researchers determined that the jets that had produced the lobes of radio-emitting gas are no longer active. Since the radio-emitting gas no longer has a power source, it is at the mercy of the expanding hot gas and has been pushed aside.
