XMM - Newton study of the two - dimensional structure of the REFLEX - DXL galaxy clusters
We carry out a two-dimensional study of temperature, entropy and pressure distributions in a nearly volume-limited subsample of REFLEX clusters at redshift 0.3, the REFLEX-DXL. We use the observations gained by XMM-Newton, which cover the central 1−2× r500. We define the substructure in both entropy and pressure as a deviation from the mean profile of the sample. The non-parametric locally weig...
متن کاملXmm – newton AO - 1 observations of three SHARC galaxy clusters
We present the follow-up of three medium redshift galaxy clusters from the SHARC survey observed with Xmm–newton. We studied RX J0256.5+0006 which shows two components which are very likely in interaction. The smallest component exhibits a comet-like structure indicating ram pressure stripping as it falls onto the main cluster. The second cluster, RX J2237.0-1516 is an elliptical cluster with a...
متن کاملXMM - Newton observations of the diffuse X - ray emission in the starburst galaxy NGC 253 ⋆
Aims. We present a study of the diffuse X-ray emission in the halo and the disc of the starburst galaxy NGC 253. Methods. After removing point-like sources, we analysed XMM-Newton images, hardness ratio maps and spectra from several regions in the halo and the disc. We introduce a method to produce vignetting corrected images from the EPIC pn data, and we developed a procedure that allows a cor...
متن کاملXmm - Newton Observations of the Diffuse X - ray Background
We analyzed two XMM-Newton observations in the direction of the high density, high latitude, neutral hydrogen cloud MBM20 and of a nearby low density region that we called the Eridanus hole. The cloud MBM20 is at a distance evaluated between 100 and 200 pc from the Sun and its density is sufficiently high to shield about 75% of the foreground emission in the 3/4 keV energy band. The combination...
متن کاملThe X-ray Properties of the Nearby Star-forming Galaxy Ic 342: the Xmm-newton View
We present results on the X-ray properties of IC 342 using a 10 ks XMM-Newton observation. Thirty-five sources are detected coincident with the disk of IC 342 (more than tripling the number known), of which ≈ 31 are likely to be intrinsic to IC 342. This point-source population exhibits a diverse range of spectral properties and has an X-ray luminosity function slope and infrared luminosity com...
