The appearance of supermassive black holes at very early times1–3 in the Universe is a challenge to our understanding of star and black hole formation. The dir…

The close proximity of the haloes enables a sufficient Lyman-Werner flux to effectively dissociate H-2 in the core of the atomic cooling halo.

The background Lyman-Werner flux manipulates the chemical properties of the gas in the collapsing halo by destroying H_2. We find that only ...

We also explored the dynamics of metal-poor mini-halos, enriched by Pop III supernova, in varying metallicities and Lyman-Werner flux to produce a fit for the minimum collapse mass. Furthermore, Pop III stars are significant drivers of reionization at high redshift (z$>$10). We use semi-numeric methods including Pop III ...

We find that for direct collapse to account for BHs in normal galaxies, the critical Lyman-Werner flux required for direct collapse must be much ...

The close proximity of the haloes enables a sufficient Lyman-Werner flux to effectively dissociate H2 in the core of the atomic cooling halo. A mild background may also be required to delay star formation in the atomic cooling halo, often attributed to distant background galaxies. In this paper, we investigate the impact of ...

... characteristic mass of $\rm 10^{5} M_{\odot}$ are formed in the presence of strong Lyman Werner flux which leads to an isothermal collapse.

In a recent high-resolution simulation, Yoshida et al. (2003) quan- tified the effects of the feedback (not taking pre-heating into ac- count), and found that UV photodissociation is effective in sup- pressing cooling in small haloes if the Lyman–Werner flux is above. J21 > 10−2, but is ineffective in larger haloes ...
