Neutral hydrogen absorption adds a frequency-dependent optical depth to the CMB at long radio wavelengths, providing a new probe of x_HI/T_s during the dark ages and reionization.
New method maps 21cm cosmological structures to ~100m reflection scales for HERA-like and EDGES-like instruments, showing near-field beam calibration is required.
