Abstract | We have detected a 200-kpc scale shock in the intracluster medium surroundingthe FRII radio galaxy 3C 444 in a short Chandra observation. Our existing datahave allowed us to identify a sharp surface brightness discontinuity and a cleartemperature jump, which corresponds to a Mach number of at least 1.7. This isthe clearest example to date of a shock associated with a powerful FRII radiogalaxy, and potentially the strongest cluster-scale radio-galaxy shock detectedto date. We request a deep XMM-Newton observation in order to obtain accuratemeasurements of the shock conditions and a detailed map of the ICM temperaturedistribution, which will enable us to confirm the shock strength and carry outthe first detailed investigation of the environmental impact of an FRII radio galaxy. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
