THE INTRAGROUP VERSUS THE INTRACLUSTER MEDIUM [PDF]
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 ...

Formation of multiphase plasma in galactic haloes and an analogy to solar plasma
Thermal instability (TI) potentially explains the origin of cold gas in the intracluster medium (ICM), which is heated sufficiently by AGN feedback. The Hα filaments seen in cluster cores provide strong motivation for TI.

Electron Reacceleration via Ion Cyclotron Waves in the Intracluster Medium
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.

Mapping the intracluster medium temperature in the era of NIKA2 and MUSTANG-2 [PDF]
We present preliminary results from an on-going program that aims at mapping the intracluster medium (ICM) temperature of high redshift galaxy clusters from the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by Chandra and high ...

The Magnetothermal Instability in the Intracluster Medium [PDF]
The electron mean free path in the intracluster medium (ICM) of galaxy clusters is much larger than the gyroradius; thus, heat is transported anisotropically along magnetic field lines. We show that the intracluster medium is unstable to the magnetothermal instability (MTI) using MHD simulations with anisotropic thermal conduction.

Cosmological simulations of the intracluster medium [PDF]
We investigate the properties of the intracluster medium (ICM) that forms within N-body/hydrodynamical simulations of galaxy clusters in a \LambdaCDM cosmology. When radiative cooling and a simple model for galactic feedback are included, our clusters have X-ray luminosities and temperatures in good agreement with observed systems, demonstrating the ...

Evidence for strong intracluster magnetic fields in the early Universe [PDF]
The origin of magnetic fields in clusters of galaxies is still a matter of debate. Observations for intracluster magnetic fields over a wide range of redshifts are crucial to constrain possible scenarios for the origin and evolution of the fields. (Differences of Faraday rotation measures (RMs) of an embedded double radio sources, i.e.
