The complex galaxy cluster Abell 514: New results obtained with the XMM-Newton satellite.

Abstract (from CDS):

We study the X-ray morphology and dynamics of the galaxy cluster Abell 514. Also, the relation between the X-ray properties and Faraday Rotation measures of this cluster are investigated in order to study the connection of magnetic fields and the intra-cluster medium.We use two combined XMM-Newton pointings that are split into three distinct observations.The data allow us to evaluate the overall cluster properties like temperature and metallicity with high accuracy. The cluster has a temperature of 3.8±0.2keV and a metallicity of 0.22±0.07 in solar units. Additionally, a temperature map and the metallicity distribution are computed, which are used to study the dynamical state of the cluster in detail. Abell 514 represents an interesting merger cluster with many substructures visible in the X-ray image and in the temperature and abundance distributions. These results are used to investigate the connection between the ICM properties and the magnetic field of the cluster by comparing results from radio measurements. The new XMM-Newton data of Abell 514 confirm the relation between the X-ray brightness and the sigma of the Rotation Measure (SXRM relation).
