Simulations show hybrid foreground mitigation (GPR + PCA combined with avoidance) recovers the HI 21cm signal within 2σ for gain calibration errors ≤1% in SKA1-Low AA* observations over 0.05-0.5 Mpc^{-1} scales.
The paper reviews cosmological tensions including the H0 and S8 discrepancies and explores new physics models that could explain them.
