Measurement of the dark matter velocity anisotropy in galaxy clusters
Ole Host,Steen H. Hansen,Rocco Piffaretti,Andrea Morandi,Andrea Morandi,Stefano Ettori,Scott T. Kay,Riccardo Valdarnini +7 more
TL;DR: In this paper, the radial profile of the velocity anisotropy of the dark matter halo in a galaxy cluster from X-ray observables of the intracluster gas is inferred.

Can giant radio halos probe the merging rate of galaxy clusters
TL;DR: In this paper, the authors carried out an explorative study that combines the observed fractions of merging clusters (fm) and RH (fRH) with the merging rate predicted by cosmological simulations and attempt to infer constraints on merger properties of clusters that appear disturbed in X-rays and of clusters with RH.
The gravitational field of X-COP galaxy clusters
Dominique Eckert,Stefano Ettori,Etienne Pointecouteau,Remco F. J. van der Burg,S. I. Loubser +4 more
TL;DR: In this paper , a nonparametric framework was introduced to reconstruct the shape of the mass of a massive dark matter halos under the assumption of hydrostatic equilibrium and compared to the expectations of Navarro-Frenk-White (NFW) and Einasto parametric mass profiles.

Gas temperature profiles in galaxy clusters with Swift XRT: observations and capabilities to map near R200
TL;DR: In this article, the authors investigated the possibility of using the X-ray telescope (XRT) on board the Swift satellite to improve the current accuracy of the intra-cluster medium (ICM) temperature measurements in the region close to the virial radius of nearby clusters.

Entropy profiles in X-ray luminous galaxy clusters at z>0.1
Andrea Morandi,Stefano Ettori +1 more
TL;DR: In this article, the authors study the profiles and the scaling properties of the gas entropy in 24 hot (kT_{gas} > 6 keV) galaxy clusters observed with Chandra in the redshift range 0.14-0.82 and showing different states of relaxation.
