AN ATTRACTOR FOR THE DYNAMICAL STATE OF THE INTRACLUSTER MEDIUM [PDF]
The Astrophysical Journal, 2012 Galaxy clusters provide us with important information about the cosmology of our universe. Observations of the X-ray radiation or of the SZ effect allow us to measure the density and temperature of the hot intergalactic medium between the galaxies in a cluster, which then allow us to calculate the total mass of the galaxy cluster.

A Two‐Temperature Model of the Intracluster Medium [PDF]
The Astrophysical Journal, 1998 We investigate evolution of the intracluster medium (ICM), considering the relaxation process between the ions and electrons. According to the standard scenario of structure formation, ICM is heated by the shock in the accretion flow to the gravitational potential well of the dark halo.

Stability analysis of convection in the intracluster medium [PDF]
Physics Letters A, 2016 We use the machinery usually employed for studying the onset of Rayleigh--Bénard convection in hydro- and magnetohydro-dynamic settings to address the onset of convection induced by the magnetothermal instability and the heat-flux-buoyancy-driven-instability in the weakly-collisional magnetized plasma permeating the intracluster medium.

Power spectrum estimation methods on intracluster medium surface brightness fluctuations [PDF]
EPJ Web of ConferencesAccurate estimation of galaxy cluster masses is a central problem in cosmology. Turbulence is believed to introduce significant deviations from the hydrostatic mass estimates.

Missing thermal energy of the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 The Sunyaev-Zel'dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot electrons in the intracluster medium (ICM). We report a 9-sigma detection of the SZ signal in the CMB maps of Wilkinson Microwave Anisotropy Probe (WMAP) 3yr data,

Heating of the intracluster medium
The Astrophysical Journal, 1990 The gravitational interaction of the system of galaxies and the ICM are treated by fluctuation theory. Fluctuation theory seems to be more adequate to describe the gravitational interaction than local theories used up to now, because gravitation is a long-range force.

Formation of multiphase plasma in galactic haloes and an analogy to solar plasma
Frontiers in Astronomy and Space Sciences, 2023 Thermal instability (TI) potentially explains the origin of cold gas in the intracluster medium (ICM), which is heated sufficiently by AGN feedback. The Hα filaments seen in cluster cores provide strong motivation for TI.

Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]
EPJ Web of ConferencesThrough observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.
