DEFROST algorithm disentangles Galactic and extragalactic Faraday rotation in RM catalogs, recovering extragalactic parameters within 5 sigma for sources at absolute Galactic latitude above 45 degrees.
A 4.5σ excess RM dispersion of 4.13 ± 0.91 rad m^{-2} is found in 191 Mg II sightlines versus controls, implying model-dependent CGM magnetic fields of 0.4-0.8 μG at projected radii 20-150 kpc and z~1.14.
SPICE-RACS DR2 delivers the largest single Faraday rotation measure catalog from a radio survey, with 250,000-340,000 RMs across most of the sky at median uncertainty of 2 rad m^{-2}.
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.
Deep 3 GHz polarised source counts detect 65 sources (51 deg^{-2}), consistent with 1.4 GHz literature due to spectral index and depolarisation, with a 2σ upper limit of <2.0 deg^{-2} on polarised SFG density.
Including radiative losses in analytic models of high-redshift radio galaxies reduces predicted radio and X-ray luminosities compared to models that neglect them.
Bayesian analysis of SKA Faraday rotation data can constrain magnetization in galaxy clusters using about 50,000 measurements with precise redshifts, while filaments remain challenging even with 17,000 spectroscopic redshifts.
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.
Overview paper summarizing SKA science cases, observational techniques, and strategies for cosmic magnetism studies across scales.
The paper reviews radio galaxy physics and outlines SKA-enabled studies of jet duty cycles, episodic activity, and dying sources.
A review of Faraday Rotation Measure Synthesis techniques and SKA Array Assembly stages for high-resolution Faraday tomography of cosmic magnetic structures.
The paper describes the expected capabilities of the SKA-Mid survey to produce a complete map of the Milky Way's magnetic field in the southern hemisphere using rotation measures and polarized emission.
Review summarizing observational data on the Milky Way's magnetic field structure, including spiral alignment, halo components, turbulence, and correlations with interstellar gas and dust.
