Watch Your Cavities

Black holes can be very violent, and a recent observation by the Chandra X-ray observatory found the most violent one. The image above shows a composite X-ray and radio image of a galaxy cluster called MS 0735.6+7421. The bright central part is believed to be emission from the supermassive black hole at the center of the biggest galaxy in the cluster. The X-ray emission, in red, shows 2 cavities on either side of the black hole. There's little X-ray emission from these cavities, but observations from the VLA (in blue) show that the cavities are filled with electrons producing radio emission. These cavities are believed to have been created by a major outburst of the black hole, possibly the most powerful explosion ever observed.
