The JWST early galaxy crisis resolved by a reionization degeneracy
A known degeneracy between star formation efficiency and ionizing escape fraction is broken using JWST UV luminosity function shapes, excluding the early galaxy crisis at 4.5 sigma and yielding the first f_esc(z) reconstruction from z=7 to 12.
