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.

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).

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.

Modelling the Energy Spectra of Radio Relics
Galaxies, 2021 Radio relics are diffuse synchrotron sources that illuminate shock waves in the intracluster medium. In recent years, radio telescopes have provided detailed observations about relics.

The nature of the motions of multiphase filaments in the centers of galaxy clusters
Frontiers in Astronomy and Space Sciences, 2023 The intracluster medium (ICM) in the centers of galaxy clusters is heavily influenced by the “feedback” from supermassive black holes (SMBHs). Feedback can drive turbulence in the ICM and turbulent dissipation can potentially be an important source of ...

The youth of the intracluster medium
Astronomy & AstrophysicsContext. Protoclusters of galaxies are the earliest phase in the assembly of galaxy clusters, and they can provide invaluable information about plasma physics, cosmic magnetism, and cosmology. However, due to small angular sizes and cosmological dimming,

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.

Galaxies, 2023 The Fanaroff–Riley Class II radio galaxy Cygnus A hosts jets that produce radio emission, X-ray cavities, cocoon shocks, and X-ray hotspots, where the jet interacts with the ICM.
