چکیده
ABSTRACT X-ray images of galaxy clusters often show disturbed structures that are indications cluster mergers. To complement our previous work on the dynamical state 964 observed by Chandra, we process for 1308 from XMM–Newton archival data, together with 22 newly released and evaluate their these images. The concentration index c, centroid shift ? power ratio P3/P0 calculated in circular regions a certain radius 500 kpc, morphology ? is estimated within elliptical can be adapted to size shape. In addition, parameters 42 previously Chandra upgraded based available redshifts. Good consistence found between derived overlapped sample two data sets. dependence mass scaling relations shown using 388 clusters.

The Dynamical State of Massive Galaxy Clusters
We study the mass distribution of a sample of 24 X-ray bright Abell clusters through weak gravitational lensing. This method is independent of the dynamical state of the galaxy cluster. Hence, by comparing dynamical and lensing mass estimators, we can access the dynamical state of these clusters. We have found that clusters with ICM temperatures above 8 keV show strong deviations from the relax...
متن کاملX-ray Surveys of Distant Galaxy Clusters
I review recent observational progress in the search for and study of distant galaxy clusters in the X-ray band, with particular emphasis on the evolution of the abundance of X-ray clusters out to z ∼1. Several on-going deep X-ray surveys have led to the discovery of a sizeable population of clusters at z > 0.5 and have the sensitivity to detect clusters beyond redshift one. These surveys have ...
متن کاملX–Ray galaxy clusters: constraints on models of galaxy formation
We present a self–consistent approach to the modeling of X–ray clusters of galaxies in a flat universe. Employing the Press & Schechter (1974) formalism to derive the mass function and relating the observable properties of clusters to their virial mass allows us to study the cluster X–ray distribution functions and their evolution with redshift. This approach differs from some results based on ...
متن کاملScaling laws in X - ray Galaxy Clusters
We present a study of the integrated physical properties of a sample of 28 X-ray galaxy clusters observed with Chandra at redshift between 0.4 and 1.3. In particular, we have twelve objects in the redshift range 0.4–0.6, five between 0.6 and 0.8, seven between 0.8 and 1 and four at z >1.0, compounding the largest sample available for such a study. We focus particularly on the properties and evo...
متن کاملHard X-ray Emission from Accretion Shocks around Galaxy Clusters
We show that the hard X-ray (HXR) emission observed from several galaxy clusters is naturally explained by a simple model, in which the nonthermal emission is produced by inverse Compton scattering of cosmic microwave background photons by electrons accelerated in cluster accretion shocks: The dependence of HXR surface brightness on cluster temperature is consistent with that predicted by the m...
