Cosmological MHD simulation of a cooling flow cluster
Context. Various observations of magnetic fields in the intra–cluster medium (ICM), most of the time restricted to cluster cores, point towards a field strength of a few μG (synchrotron radiation from radio relics and radio halos, inverse Compton radiation in X-rays and Faraday rotation measure of polarised background sources). Both the origin and the spatial structure of galaxy cluster magneti...

15 صفحه اولHRI observation of the cooling flow cluster
A ROSAT HRI observation of the cluster MS-0839.9+2938 at z=0.194 is presented. It confirms the earlier suggestion, based on the detection of extended Hα emission, that the inner regions of this cluster are dominated by a cooling flow. The surface brightness distribution within the cooling radius shows structures which can be interpreted as evidence of a highly inhomogeneous space distribution o...
متن کاملChandra Observation of the Cooling Flow Cluster
We present an analysis of the Chandra X-ray observation of A2052, including large-scale properties of the cluster as well as the central region, which includes the bright radio source 3C 317. We present temperature and abundance profiles using both projected and deprojected spectral analyses. The cluster shows the cooling flow signatures of excess surface brightness above a -model at the cluste...
متن کاملA Three-Dimensional MHD Simulation of Plasma Flow Past Io
We describe a time-dependent three-dimensional magnetohydrodynamic (MHD) simulation of plasma flow past Jupiter's satellite Io. The simulation starts with a uniform, magnetized flow interacting with a finite conducting sphere (representing Io), and the integration is carried forward in time until a quasi-steady state develops. Previously we have reported on the presence of standing slow mode pe...
