Forecasts show SKA-Mid cross-correlations with ET/CE gravitational wave events can constrain GW source bias and time-delay distributions.
Pilot FAST HD² survey reports 339 new HI detections in 10 deg² with 0.45 mJy rms, high DESI optical matching rates, and gas fraction relations consistent with ALFALFA, DINGO, and xGASS.
Overview of HI modeling methods finds consistency in cosmic HI density but systematic differences in HI-halo mass relation shape and redshift evolution.
Review of state-of-the-art cosmological galaxy formation models for HI, molecular gas and radio continuum in preparation for SKA, advocating coordinated multi-scale simulations, forward modelling and AI emulators.
