Formation of supermassive black holes by direct collapse in pre-galactic haloes
Formation of supermassive black holes by direct collapse in pre-galactic haloes
We describe a mechanism by which supermassive black holes can form directly in the nuclei of protogalaxies, without the need for seed black holes left over from early star formation. Self-gravitating gas in dark matter halos can lose angular momentum rapidly via runaway, global dynamical instabilities, the so-called "bars within …
