Scientific paper

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.
