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
Power-law modeling of gas mass fraction and temperature variation reconciles observed X-ray scaling relations in galaxy clusters, reducing >3σ tensions from 49% to 11% and yielding a redshift-independent mass proxy Y_LGT0.
Both SIMBA and TNG50 simulations underpredict OVI covering fractions around galaxy groups compared to observations, with most absorbers being gravitationally bound.
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.
FRB dispersion measures from CHIME/FRB Outrigger constrain gas mass fractions in galaxy groups and clusters, consistent with eROSITA at R500 but with mild tension at R200.
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.
