| Description | We propose an XMM-Newton observation of the galaxy cluster Abell 2254 (z=0.178), which contains a remarkably powerful radio halo compared to the strength of its X-ray emission. This target has never before been observed with XMM-Newton or Chandra; it was detected in the ROSAT All-Sky Survey and is an X-ray bright system. The presence of a luminous, diffuse radio halo suggests that Abell 2254 is a dynamically young merging cluster undergoing a major merger event. We propose to carry out the first detailed X-ray study of the cluster and mapping, in detail, the complex thermodynamics of the merger. We will search for cold fronts, shocks and other sites of particle acceleration, and place limits on possible .non-thermal. emission. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
