4C+00.58: Black Hole Jerked Around Twice
The close-up view in the inset shows a composite image of the galaxy 4C +00.58 in X-rays from Chandra (gold) and radio waves from the Very Large Array (blue). New data suggest the giant black hole has been flipped around, causing its spin axis to point in a different direction from before. The deep Chandra X-ray image shows hot gas in and around 4C +00.58 and reveals four different cavities -- regions of lower than average X-ray emission -- around the black hole. The X-ray data when combined with the radio information suggests that collisions with other galaxies may have caused the black hole to shift the direction it was spinning.
