Radio observations of Faraday rotation in CARLA J1510+5958 at z=1.72 yield a lower limit of 0.4 μG on the average magnetic field strength in the proto-intra-cluster medium.
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.
New radio observations at cold fronts in galaxy clusters lead to the proposal that magnetic reconnection, rather than Fermi acceleration, re-accelerates particles at these contact discontinuities.
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
Multi-component modeling of 1565 LoTSS-DR2 sources shows 43% have complex Faraday structure, external dispersion dominates in 54%, and rest-frame dispersion correlates positively with redshift in external and mixed populations.
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.
Fornax cluster magnetic field follows a power-law spectrum of slope ~2.7 with central strength ~5 μG scaling as n^1.6, consistent with recent central re-amplification and trends across 17 clusters.
Including radiative losses in analytic models of high-redshift radio galaxies reduces predicted radio and X-ray luminosities compared to models that neglect them.
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.
Models predict SKA-Low will deliver an RM grid of over 50,000 sources in a 10,000 deg² survey at ~0.05 rad/m² precision, at least 10x denser than current m-λ grids.
Proposes SKA observations of El Gordo to study high-redshift ICM magnetic fields via continuum and polarization measurements and test amplification models.
Predictions show the SKA-mid RM grid will deliver higher precision and accuracy for intra-cluster and intra-group magnetic field studies than POSSUM.
Overview of how the SKAO will enable studies of star-forming galaxies, AGN co-evolution, and diffuse emission in clusters and the cosmic web using continuum radio observations.
