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}.
Hybrid imperfections cause parallactic-angle-dependent leakage in pseudo-circular feeds via non-commutative Jones matrix interaction, and a SOP pre-correction is introduced to remove it before sky-frame projection.
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.
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.
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.
MHD simulations forecast polarized synchrotron emission in clusters and filaments to assess SKA detection capabilities.
SKAO will enable detection of synchrotron emission from prestellar cores to probe their magnetic field properties in nearby star-forming regions.
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.
SKA will enable Zeeman measurements of magnetic fields from cometary comas through Galactic structures and starburst galaxies to damped Ly-alpha systems at cosmological redshifts, with achievability tied to array assembly stages.
Overview paper summarizing SKA science cases, observational techniques, and strategies for cosmic magnetism studies across scales.
Proposes SKA surveys for a census of galactic magnetic fields from low to high redshift using polarimetry, RM grids, and lensed quasars to constrain dynamo models.
A review of Faraday Rotation Measure Synthesis techniques and SKA Array Assembly stages for high-resolution Faraday tomography of cosmic magnetic structures.
Reviews SKA techniques for reconstructing 3D magnetic field vectors in the ISM but presents no new data or derivations.
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.
This review chapter summarizes the cosmic web's theoretical framework, recent radio observations of diffuse gas, and the expected impact of the SKA on detecting baryons in filaments and cluster outskirts.
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.
