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--B nard 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.

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.

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.

The X-Ray Intracluster Medium [PDF]
Symposium - International Astronomical Union, 1996 Clusters of galaxies are the largest aggregates of matter that have decoupled from the universal expansion and have approximately evolved to a proper dynamical equilibrium configuration. While in the optical they are just observed as dense concentrations of galaxies, they are seen in X-rays as continuously connected entities through the emission of the

ASCA Measurements of Silicon and Iron Abundances in the Intracluster Medium [PDF]
, 1998 We analyzed the ASCA X-ray data of 40 nearby clusters of galaxies, whose intracluster-medium temperature distributes in the range of 0.9--10 keV. We measured the Si and Fe abundances of the intracluster medium, spatially averaging over each cluster, but excluding the central $\sim 0.15 h_{50}^{-1}$ Mpc region in order to avoid any possible abundance ...

Turbulence in the intracluster medium: simulations, observables & thermodynamics [PDF]
, 2019 We conduct two kinds of homogeneous isotropic turbulence simulations relevant for the intracluster medium (ICM): (i) pure turbulence runs without radiative cooling; (ii) turbulent heating$+$radiative cooling runs with global thermal balance.
