Strong [OIII]+Hβ emitters at z~7 represent 56% of the UV-selected population by number density and contribute ~70% of the ionizing budget required for reionization.
Empirical three-parameter fit to f_esc(M_h,z) yields steep redshift evolution with population-averaged escape fraction rising from ~2% at z=5 to ~9% at z=12.
Far-IR stacking of ~4000 LAEs at z=2-6 yields detections in massive AGN hosts with low f_esc(Lyα) (1-7%) and higher values (>10%) in undetected stacks, plus elevated IRX relative to typical star-forming galaxies.
SPRITE SmallSat is predicted to detect LyC from low-z LCEs using advanced FUV coatings and spectrograph, with eight prior LCEs as commissioning targets to validate sensitivity and enable a larger survey bridging low- and high-redshift studies.
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.
Proposal for multi-orbit panchromatic UV spectroscopy with boosted HST to study the shape of escaping ionizing radiation and star formation histories in galaxies at modest redshift.

Steep Redshift Evolution of the Ionizing Escape Fraction at $z = 5$--$12$: Empirical Constraints and Comparison with Simulations
Empirical three-parameter fit to f_esc(M_h,z) yields steep redshift evolution with population-averaged escape fraction rising from ~2% at z=5 to ~9% at z=12.
