Spatial distributions of the galaxy clusters at medium redshifts observed by XMM-Newton
Abstract
We present XMM-Newton results on the spatially resolved X-ray properties of the galaxy clusters at medium redshifts. Useful temperature measurements could be performed out to radii with overdensity 500. The scaled temperature distributions show good similarities. The high resolution temperature and pressure distributions contribute to a more accurate gravitational mass and gas mass fraction measurements, which can be used not onlyas cosmological probes, but also for astrophysical studies like the statistics of cluster substructure, galaxy evolution, Sunyaev-Zel'dovich observations and many other applications.
