The Baryon Catastrophe and the multiphase intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 1996 We review the theories and observations which together have led to the concept of the Baryon Catastrophe: observations of the baryon fraction on the scale of clusters of galaxies appear to be at least three times as high as the universal baryon fraction predicted by the theory of primordial nucleosynthesis in a flat, $ _0 = 1$, universe.

Dynamical evolution of magnetic fields in the intracluster medium [PDF]
, 2019 We investigate the evolution of magnetic fields in galaxy clusters starting from constant primordial fields using highly resolved ($\approx \rm 4 ~kpc$) cosmological MHD simulations.

Sunyaev-Zel'dovich polarization as a probe of the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We present high-resolution hydrodynamical simulations of the degree and direction of polarisation imprinted on the CMB by the Sunyaev-Zel'dovich effect in the the line of sight to massive galaxy clusters. We focus on two contributions which contribute most of the induced CMB polarisation in addition to the intrinsic CMB quadrupole: the radiation ...

MHD turbulence in the intracluster medium [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractIn this work we discuss the turbulent evolution of structures in the intracluster medium based on the two fluid approximations: MHD and collisionless plasma under Chew Goldberger Low (CGL) closure. Turbulence excited by galactic motions and gas inflow in intracluster medium will develop in very different ways considering the two fluid ...

Turbulence decay in the density-stratified intracluster medium
, 2019 Turbulence evolution in a density-stratified medium differs from that of homogeneous isotropic turbulence described by the Kolmogorov picture. We evaluate the degree of this effect in the intracluster medium (ICM) with hydrodynamical simulations. We find

Buoyancy Instabilities in a Weakly Collisional Intracluster Medium
, 2012 The intracluster medium of galaxy clusters is a weakly collisional, high-beta plasma in which the transport of heat and momentum occurs primarily along magnetic-field lines.

Non-thermal particles in the intergalactic and intracluster medium [PDF]
arXiv, 2004 I present a review of nonthermal processes in the large scale structure of the universe. After examining the properties of cosmological shock waves and their role as particle accelerators, I discuss the main observational facts, from radio to \gr and describe the processes that are thought be responsible for the observed nonthermal emissions.

Investigation of Properties of the Intercluster Medium Rich Clusters of Galaxies [PDF]
arXiv, 2010 The statistical analysis of properties of 213 rich clusters of galaxies is performed. The existence of correlations between the X-ray luminosity and the temperature of the intracluster medium and between the X-ray luminosity and the velocity dispersion of the galaxies is confirmed.
