The Enrichment of the Intracluster Medium [PDF]
Symposium - International Astronomical Union, 1996 Recent observational evidence for steep dwarf galaxy luminosity functions in several rich clusters has led to speculation that their precursors, via supernovae (SNe)-driven galactic winds, may be the source of the majority of gas and metals inferred from intracluster medium (ICM) x-ray observations (Trentham 1994).

The Astrophysical Journal, 2023 The galaxy cluster Zwicky 3146 is a sloshing cool-core cluster at z = 0.291 that in Sunyaev–Zel’dovich (SZ) imaging does not appear to exhibit significant pressure substructure in the intracluster medium.

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.

CHANDRA X-Ray Observations of A119: Cold Fronts and a Shock in an Evolved Off-axis Merger
The Astrophysical Journal, 2023 We present Chandra X-ray observations of the dynamically complex galaxy cluster A119 ( z = 0.044). A119 is host to two narrow-angle-tail (NAT) radio sources (0053-015 and 0053-016), whose tails are oriented parallel to each other, despite orthogonally ...

A Heating Mechanism via Magnetic Pumping in the Intracluster Medium
The Astrophysical Journal, 2023 Turbulence driven by active galactic nuclei activity, cluster mergers, and galaxy motion constitutes an attractive energy source for heating the intracluster medium (ICM).

Plasma Physics of the Intracluster Medium
, 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

Mirror Acceleration of Cosmic Rays in a High-β Medium
The Astrophysical Journal, 2023 In a weakly compressible high- β medium, pitch-angle scattering and the associated scattering acceleration of cosmic rays (CRs) by anisotropic Alfvén and slow modes of magnetohydrodynamic (MHD) turbulence is inefficient.

Electron Reacceleration via Ion Cyclotron Waves in the Intracluster Medium
The Astrophysical Journal, 2023 In galaxy clusters, the intracluster medium (ICM) is expected to host a diffuse, long-lived, and invisible population of “fossil” cosmic-ray electrons (CRe) with 1–100 MeV energies.
