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…
Electromagnetic Window into the Dawn of Black Holes
Zoltán Haiman, William N. Brandt, Alexey Vikhlinin +28
Massive 10^6-10^10 Msun black holes (BHs) are ubiquitous in local galactic nuclei. They were common by the time the Universe is several Gyr old, and many of them were in place with…
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…
Feedback from the IR Background in the Early Universe
Jemma Wolcott-Green, Zoltán Haiman
It is commonly believed that the earliest stages of star-formation in the Universe were self-regulated by global radiation backgrounds - either by the ultraviolet Lyman-Werner (LW)…
Photodissociation of H2 in Protogalaxies: Modeling Self-Shielding in 3D Simulations
Jemma Wolcott-Green, Zoltán Haiman, Greg L. Bryan
The ability of primordial gas to cool in proto-galactic haloes exposed to Lyman-Werner (LW) radiation is critically dependent on the self-shielding of H_2. We perform radiative tra…
Suppression of HD-cooling in protogalactic gas clouds by Lyman-Werner radiation
Jemma Wolcott-Green, Zoltán Haiman
It has been shown that HD molecules can form efficiently in metal-free gas collapsing into massive protogalactic halos at high redshift. The resulting radiative cooling by HD can l…
