abstract
We investigate the ability of primordial gas clouds to retain molecular hydrogen (H_2) during the initial phase of the reionization epoch. We find that before the Stromgren spheres of the individual ionizing sources overlap, the UV background below the ionization threshold is able to penetrate large clouds and suppress their H_2 abundance. The consequent lack of H_2 cooling could prevent the collapse and fragmentation of clouds with virial temperatures T_vir < 10^4 K (or masses 10^8 Msun [(1+z_vir)/10]^{-3/2}). This negative feedback on structure-formation arises from the very first ionizing sources, and precedes the feedback due to the photoionization heating.

A large radiative transfer simulation of reionization confirms that fast analytic models accurately reproduce the HII bubble size distribution and the 21 cm power spectrum.
Halos exposed to Lyman-Werner backgrounds of J21 >= 10 show gas inflow rates capable of forming supermassive stars, and intermediate backgrounds (1 <= J21 < 10) are common enough to make heavy black hole seeds abundant if the same behavior extends there.
Cosmological hydrodynamical simulations predict that UV diversity in Little Red Dots encodes direct-collapse black hole ages via a rapid transition from BH- to stellar-dominated emission after ~30 Myr.
