Forward modeling of 90 localized FRBs from DSA and ASKAP yields n_z = 1.62^{+1.48}_{-1.57} for DM_host(z) ∝ (1+z)^{n_z}, excluding n_z=0 at 1σ.

Self-regulating AGN jets in MHD simulations of cool-core clusters yield realistic FRI radio morphologies viewed along the jet axis and account for frequency-independent lobe extents via 1-50 μG fields allowing both young and old electrons to radiate.
Primordial black holes captured by stars lead to either quiet consumption or explosive disruption via disk formation, producing transients and high-spin remnants with potentially observable event rates.
MeerKAT observations detect radio halos in 27% of 30 massive clusters at z>1, a rate lower than at intermediate redshifts but above model predictions, with power-mass scaling similar to lower-z samples.
