XMM - Newton Observation of the Cluster of Galaxies Abell 1060
We present results from the XMM-Newton observation of the non-cooling flow cluster A 1060. Large effective area of XMM-Newton enables us to investigate the nature of this cluster in unprecedented detail. From the observed surface brightness distribution, we have found that the gravitational mass distribution is well described by the NFW profile but with a central density slope of ∼1.5. We have ...
متن کاملXMM - Newton observation of the interacting cluster Abell 3528
We analyze the XMM-Newton dataset of the interacting cluster of galaxies Abell 3528 located westward in the core of the Shapley Supercluster, the largest concentration of mass in the nearby Universe. A3528 is formed by two interacting clumps (A3528-N at North and A3528-S at South) separated by 0.9 h −1 70 Mpc at redshift 0.053. XMM-Newton data describe these clumps as relaxed structure with an ...
متن کاملAn XMM - Newton view of the extended “ filament ” near the cluster of galaxies Abell 85
We have observed with XMM-Newton the extended 4 Mpc filament detected by the ROSAT PSPC in the neighbourhood of the cluster of galaxies Abell 85. We confirm that there is an extended feature, aligned at the same position angle as the major axis of the central cD, the bright cluster galaxies, and nearby groups and clusters. We find that the X-ray emission from the filament is best described by t...
متن کاملAn XMM - Newton view of the cluster of galaxies Abell 85
We have observed the cluster of galaxies Abell 85 with XMM-Newton. These data have allowed us to confirm in a previous paper the existence of the extended 4 Mpc filament detected by the ROSAT PSPC in the neighbourhood of this cluster, and to determine an X-ray temperature of about ∼ 2 keV. We now present a thorough analysis of the properties of the X-ray gas in the cluster itself, including tem...
متن کاملXMM-Newton and Chandra view of the Cluster Abell 85 and its X-Ray Filament
Abstract. From ROSAT data, the bright X-ray cluster Abell 85 was found to show a roughly symmetrical shape, on to which are superimposed several features, among which: (1) a blob or group of galaxies falling on to the main cluster, with the gas in the impact region probably hotter and the galaxies in that zone showing enhanced star formation; (2) a filament, either diffuse or made of small grou...
