Robust quantitative measures of cluster X-ray morphology, and comparisons between cluster characteristics
Aims. To investigate the possible relationships between dynamical status and other important characteristics of galaxy clusters, we conducted a study of X-ray cluster morphology using a sample of 101 clusters at redshift z∼0.05-1 taken from the Chandra archive. Methods. The X-ray morphology is quantitatively characterized by a series of objectively measured simple statistics of the X-ray surfac...
متن کاملComplex X-ray morphology of Abell 3128: A distant cluster behind a disturbed cluster
We present here the results of a detailed study of the X-ray properties of the cluster of galaxies Abell 3128 (z = 0.06), based on the analysis of deep (100 ks) XMM-Newton data. The most obvious feature of the X-ray morphology of A3128 is the presence of two X-ray peaks separated by ∼12. By detecting the redshifted Fe K line, we find that the Northeast (NE) X-ray peak observed toward A3128 is a...
متن کاملX-ray Constraints on Cluster Magnetic Fields
Lower limits to the intracluster magnetic field are derived from modeling broad band X-ray spectra of 6 galaxy clusters with radio halos (A401, A754, A1367, Coma (A1656), A2256, and A2319). The 0.7 10 keV spectra for all clusters were obtained with the Advanced Satellite for Cosmology and Astrophysics (ASCA) Gas Imaging Spectrometer (GIS). For A401, A754, A1367, and A1656, data from the HEAO1-A...
متن کاملX-ray cluster temperature profiles
Context. A study of the structural and scaling properties of the temperature distribution of the hot, X-ray emitting intra-cluster medium of galaxy clusters, and its dependence on dynamical state, can give insights into the physical processes governing the formation and evolution of structure. Aims. Accurate temperature measurements are a pre-requisite for a precise knowledge of the thermodynam...
متن کاملGlobular cluster x-ray sources.
Globular clusters and x-ray astronomy have a long and fruitful history. Uhuru and OSO-7 revealed highly luminous (> 10(36) ergs(-1)) x-ray sources in globular clusters, and Einstein and ROSAT revealed a larger population of low-luminosity (< 10(33) ergs(-1)) x-ray sources. It was realized early on that the high-luminosity sources were low-mass x-ray binaries in outburst and that they were order...
