How Do Direct Collapse Black Holes Form in the Early Universe?

AI Thread Summary
Direct collapse black holes (DCBHs) may form in the early universe, potentially explaining the existence of supermassive black holes (SMBHs) observed in high redshift quasars. A recent paper suggests that the ultraviolet background, previously thought to suppress DCBH formation, may not significantly limit their numbers. The authors utilized numerical simulations to explore conditions conducive to DCBH formation in atomic cooling halos. The discussion also touches on the stability of massive objects and the dynamics of gravitational collapse, with insights into how black holes of varying masses can be observed despite their event horizons. Overall, the findings could enhance understanding of the early universe's structure and the formation of SMBHs.

Do you have an MTW section number?
MTW Box 24.1, C page 620 - Chapter 32, page 842 'Gravitational Collapse', Chapter 33, page 872 'Black Holes' - and then Chapter 34, page 916 'Global Techniques, Horizons and Singularity Theorems'.

The Oppenheimer and Snyder paper was ''On Continued Gravitational Contraction' Physical Review, Sept. 1939, Vol 56.

I hope this helps,
