About this Image

XMM-Newton EPIC observations of a sample of radio-galaxy environments. In colour the X-ray emission from galaxy groups hosting nearby radio galaxies is shown. The superimposed contours indicate the radio emission from the jets and lobes of each active galaxy. Low-power radio galaxies are found to live in galaxy groups with X-ray luminosities ranging over two orders of magnitude, and appear to be having a dramatic effect on the hot intragroup gas.
