New method maps 21cm cosmological structures to ~100m reflection scales for HERA-like and EDGES-like instruments, showing near-field beam calibration is required.
Using JWST UV luminosity functions, the surface density of galaxy-driven ionized bubbles with radius ≥2.5 cMpc at z≈13 is estimated at 1.33×10^{-2} arcmin^{-2} per Δz=1 in a fiducial model with f_esc=0.2 and log ξ_ion=25.5.
Reviews multiple higher-order statistics for 21-cm intensity mapping and forecasts their detectability with SKAO, incorporating noise and foreground effects.
