Patchy reionization and patchy H2 dissociating
background in (50cMpc)3 box at z = 15.7. Contours of thick
colored lines represent different J21 contours (orange – J21=
0.1; blue – J21= 1), and the black contours represent the ionization
fronts. Minihalos are subject to spatially-varying LW
feedback effect, thus yielding spatially-varying minihalo star
formation rate. JWST may able to detect clustered minihalo
population at z ~ 15 in regions of least LW feedback.
