HI-shielding of in UV-irradiated protogalaxies: suppression of the photodissociation rate
Meredith Neyer, Jemma Wolcott-Green
We study the impact of neutral hydrogen absorption on photodissociation in protogalactic haloes exposed to soft-UV radiation. Lyman-series absorption can significantly…
Suppression of H2-cooling in protogalaxies aided by trapped Lyα cooling radiation
Jemma Wolcott-Green, Zoltan Haiman, Greg L. Bryan
We study the thermal evolution of UV-irradiated atomic cooling haloes using high-resolution three-dimensional hydrodynamic simulations. We consider the effect of H^- photodetachmen…
H2 self-shielding with non-LTE rovibrational populations: implications for cooling in protogalaxies
J. Wolcott-Green, Z. Haiman
The abundance of molecular hydrogen (H2), the primary coolant in primordial gas, is critical for the thermodynamic evolution and star-formation histories in early protogalaxies. De…
Beyond Jcrit: a critical curve for suppression of H2-cooling in protogalaxies
J. Wolcott-Green, Z. Haiman, G. L. Bryan
Suppression of H2-cooling in early protogalaxies has important implications for the formation of supermassive black holes seeds, the first generation of stars, and the epoch of rei…
