A census of ~3600 variable compact radio sources at 3 GHz from VLASS epochs 1 and 2, with 5-9% showing >30% flux changes above 20-300 mJy and most consistent with blazars or quasars.
SEMPER predicts SKA-Mid Band 2 observations in under 20 hours will recover at least 20% of the total SFRD from radio-emitting SFGs up to z≈6, including NIR-dark galaxies.
SKA-Mid is predicted to yield samples of 10-100 low-metallicity Lyman continuum emitting galaxies per square degree, enabling multi-wavelength studies of feedback processes linked to ionizing photon escape.
MeerKLASS applies on-the-fly imaging on MeerKAT for a 10,000 sq. deg. UHF-band continuum survey at 14 arcsec resolution and 25 μJy/beam rms, run commensally with HI intensity mapping.
Simulations of an SKA-Mid survey predict detection of 1.5e4 star-forming galaxies to z~7 with thermal SFR uncertainties of 0.1 dex, enabling constraints on cosmic star formation rate density.
Forecasts angular clustering for a 20,000 sq deg SKAO radio continuum survey reaching O(300-400 million) sources and discusses needed corrections for telescope systematics and population modeling.
Simulated SKA-Mid surveys reach radio-AGN completeness at L_1.4GHz ~ 10^23 W Hz^-1 up to z~6.
Simulation pipeline for SKA-Mid radio galaxies shows RadioLensfit and DeepShape recover shapes with multiplicative shear bias of a few 10^{-2} and additive bias of 10^{-4}.
Overview of HI modeling methods finds consistency in cosmic HI density but systematic differences in HI-halo mass relation shape and redshift evolution.
