Intracluster Stars and the Chemical Enrichment of the Intracluster Medium [PDF]
The Astrophysical Journal, 2004 We explore the contribution of intracluster stars (ICS) to the chemical enrichment history of the intracluster medium (ICM). In contrast to scenarios in which all the metals originate in cluster galaxies and are then transported into the ICM, intracluster stars enrich the ICM in situ, thereby contributing 100% of their supernovae ejecta directly into ...

Plasma physics of the intracluster medium [PDF]
, 2022 This Chapter provides a brief tutorial on some aspects of plasma physics that are fundamental to understanding the dynamics and energetics of the intracluster medium (ICM). The tutorial is split into two parts: one that focuses on the thermal plasma component -- its stability, viscosity, conductivity, and ability to amplify magnetic fields to dynamical

Evolution of vorticity and enstrophy in the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Turbulence generated by large-scale motions during structure formation affects the evolution of the thermal and non-thermal components of the intracluster medium. As enstrophy is a measure of the magnitude of vorticity, we study the generation and evolution of turbulence by analysing the Lagrangian history of enstrophy.

The Enrichment of the Intracluster Medium [PDF]
arXiv, 1996 The enrichment of the intracluster medium (ICM) of galaxy clusters, within the framework of the supernovae-driven wind model for elliptical galaxies, has been considered under two extreme assumptions regarding the binding energy-mass-radius relations. Unless the binding energy at the time of wind commencement, for a given galactic mass, was a factor of

DWARF GALAXIES AND THE ORIGIN OF INTRACLUSTER MEDIUM [PDF]
Astrophys.J. 454 (1995) 604, 1995 Following the recent suggestion that it is dwarf galaxies in clusters -- as opposed to large ellipticals -- that provide the intracluster gas, we estimate the metallicity of the intracluster medium (ICM) in such a case. We derive analytical expressions for the fraction of mass of dwarf galaxies that is ejected, and estimate the metallicity of the ...

Relativistic hydrodynamic jets in the intracluster medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We have performed the first three-dimensional relativistic hydrodynamic simulations of extragalactic jets of pure leptonic and baryonic plasma compositions propagating into a hydrostatic intracluster medium environment. The numerical simulations use a general equation of state for a multi-component relativistic gas which closely reproduces the Synge ...

THE ENRICHMENT OF THE INTRACLUSTER MEDIUM [PDF]
The Astrophysical Journal, 2009 To determine the relative contributions of galactic and intracluster stars to the enrichment of the intracluster medium (ICM), we present X-ray surface brightness, temperature, and Fe abundance profiles for a set of twelve galaxy clusters for which we have extensive optical photometry.

THE INTRAGROUP VERSUS THE INTRACLUSTER MEDIUM [PDF]
The Astrophysical Journal, 2016 ABSTRACT Galaxy groups differ from clusters primarily by way of their lower masses, M ∼ 1014 M ⊙ versus M ∼ 1015 M ⊙. We discuss how mass affects the thermal state of the intracluster or the intragroup medium, specifically as to their entropy levels and radial ...
