Ancient cosmic ray halos from the central galaxy boost Perseus's cool core via inverse-Compton scattering, simultaneously explaining radio minihalo, giant halo, X-ray properties, and gamma-ray data without re-acceleration.
Deep Chandra data confirms three cold fronts in RXJ2014.8-2430 with widths indicating suppressed diffusion and identifies a concave structure consistent with either a Kelvin-Helmholtz instability or a powerful AGN cavity of radius 200-330 kpc.
Ion injection at perpendicular shocks requires 3D geometry to capture the porosity of downstream magnetic turbulence that lets particles return upstream and gain energy.
Presents 24 AREPO+IllustrisTNG zoom-in simulations of clusters above 10^15 solar masses showing converged magnetic fields with volume-averaged plasma beta approximately 100 inside R200 after z~1.2, declining Faraday rotation profiles, and intermittent Braginskii heating approaching cooling rates in
A grid of 434 Faraday rotation measures from MeerKAT polarimetry reveals enhanced RM scatter in the Abell 3391/95 clusters and suggests a relatively ordered magnetic field in the intercluster bridge on ~10 kpc scales.
SKA-Mid all-sky surveys are projected to detect up to 3500 radio mini-halos at z<1 and enable a complete census of radio-loud BCGs to z~2.
MHD simulations forecast polarized synchrotron emission in clusters and filaments to assess SKA detection capabilities.
Proposes SKA observations of El Gordo to study high-redshift ICM magnetic fields via continuum and polarization measurements and test amplification models.
Review of cosmic ray production and radio emission in galaxy clusters with recommendations for SKA observations of magnetic fields and low-energy particles.
