We discuss the impact of magnetic field on the mass–temperature relation for groups and clusters of galaxies based on the derivation of the general Magnetic Virial Theorem. The presence of a magnetic field  B yields a decrease of the virial temperature  T for a fixed mass  M : such a decrease in  T is stronger for low-mass systems than for high-mass systems. We outline several implications of the presence of B -field and of its mass scaling for the structure and evolution of groups and clusters… Expand

Structure and evolution of magnetized clusters : entropy profiles, S -T and LX-T relations
We study the impact of an intracluster magnetic field on the main structural properties of clusters and groups of galaxies: the radial density and entropy profiles, the entropy – temperature relationExpand
Magnetic fields and Sunyaev-Zel'dovich effect in galaxy clusters
In this work we study the contribution of magnetic fields to the Sunyaev Zeldovich (SZ) effect in the intracluster medium. In particular we calculate the SZ angular power spectrum and the centralExpand
Beyond the standard lore of the SZ effect
Abstract The recent X-ray, optical and radio observations of galaxy clusters indicate that the atmospheres of these cosmic structures consist of a complex structure of thermal (hot and warm) andExpand
On the ability of spectroscopic SZ effect measurements to determine the temperature structure of galaxy clusters
(abridged) We explore in this paper the ability of spatially resolved spectroscopic measurements of the SZ effect (SZE) to determine the temperature profile of galaxy clusters. We derive a generalExpand
Searching for cool core clusters at high redshift
Aims. We investigate the detection of Cool Cores (CCs) in the distant galaxy cluster population with the purpose of measuring the CC fraction out to redshift 0.7 ≤ z 0.7, and should also be relatedExpand

Correlation of the magnetic field and the intra-cluster gas density in galaxy clusters
We present a correlation between X-ray surface brightness and Faraday rotation measure in galaxy clusters, both, from radio and X-ray observations as well as from modeling of the intra-clusterExpand
The X‐ray virial relations for relaxed lensing clusters observed with Chandra
We examine the relations linking mass, X-ray temperature and bolometric luminosity for a sample of luminous, relatively relaxed clusters of galaxies observed with the Chandra Observatory, for whichExpand
Thermal Conduction in Clusters of Galaxies
We estimate the thermal conductivity of a weakly collisional magnetized plasma with chaotic magnetic field fluctuations. When the fluctuation spectrum extends over two or more decades in wavevector,Expand
Evolution and structure of magnetic fields in simulated galaxy clusters
We use cosmological magneto-hydrodynamic simulations to study the evolution of magnetic elds in galaxy clusters in two dierent cosmological models, a standard-CDM and a -CDM model. We show that theExpand
Where does the hard X-ray diffuse emission in clusters of galaxies come from?
The surface brightness produced by synchrotron radiation in clusters of galaxies with a radio-halo sets a degenerate constraint on the magnetic field strength, the relativistic electron density andExpand
Is the Cluster Temperature Function a Reliable Test for Ω0
We discuss the evolution of the cluster temperature function (TF) in different scenarios for structure formation. We use the commonly adopted procedure of fitting the model parameters to the local TFExpand
