INTRACLUSTER MEDIUM ENTROPY PROFILES FOR A CHANDRA ARCHIVAL SAMPLE OF GALAXY CLUSTERS
The Astrophysical Journal Supplement Series, 2009 We present radial entropy profiles of the intracluster medium (ICM) for a collection of 239 clusters taken from the Chandra X-ray Observatory's Data Archive. Entropy is of great interest because it controls ICM global properties and records the thermal history of a cluster.

ADAPTIVELY REFINED LARGE EDDY SIMULATIONS OF A GALAXY CLUSTER: TURBULENCE MODELING AND THE PHYSICS OF THE INTRACLUSTER MEDIUM [PDF]
The Astrophysical Journal, 2009 We present a numerical scheme for modeling unresolved turbulence in cosmological adaptive mesh refinement codes. As a first application, we study the evolution of turbulence in the intracluster medium (ICM) and in the core of a galaxy cluster. Simulations with and without subgrid scale (SGS) model are compared in detail.

Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Well-resolved galaxy clusters often show a large-scale quasi-spiral structure in deprojected density ρ and temperature T fields, delineated by a tangential discontinuity known as a cold front, superimposed on a universal radial entropy profile with a linear K(r) ∝ Tρ−2/3 ∝ r adiabat.

Iron abundances and heating of the intracluster medium in hydrodynamical simulations of galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 Results from a large set of hydrodynamical smoothed particle hydrodynamics (SPH) simulations of galaxy clusters in a flat ΛCDM cosmology are used to investigate the metal enrichment and heating of the intracluster medium (ICM). The physical modelling of the gas includes radiative cooling, star formation, energy feedback and metal enrichment which ...

SDSS-C4 3028: the Nearest Blue Galaxy Cluster Devoid of an Intracluster Medium
The Open Journal of AstrophysicsSDSS-C4 3028 is a galaxy cluster at z = 0.061 , notable for its unusually high fraction of star-forming galaxies with 19 star-forming and 11 quiescent ...

Measuring the intracluster medium velocity structure within the A3266 galaxy cluster
Astronomy & AstrophysicsWe present a detailed analysis of the velocity structure of the hot intracluster medium (ICM) within the A3266 galaxy cluster, including new observations taken between June and November 2023. Firstly, morphological structures within the galaxy cluster were examined using a Gaussian gradient magnitude (GGM) and an adaptively smoothed GGM filter applied ...

Cosmic evolution of the Faraday rotation measure in the intracluster medium of galaxy clusters
Astronomy & AstrophysicsContext. Radio observations have revealed magnetic fields in the intracluster medium (ICM) of galaxy clusters, and their energy density is nearly in equipartition with the turbulent kinetic energy. This suggests magnetic field amplification by dynamo processes during cluster formation.

Ram‐Pressure Stripping of Galaxies in High‐Redshift Clusters and the Influence of Intracluster Medium Heating [PDF]
The Astrophysical Journal, 2001 We have investigated the ram-pressure stripping of disk galaxies in clusters at various redshifts and in cluster progenitors; the clusters grow up on a hierarchical clustering scenario. We consider a radially infalling galaxy whose initial position and velocity are given by a spherical collapse model of structure formation. Moreover, since observations
