Description
The existence of supermassive black holes is confirmed at z 6. We explore their formation in the early universe performing high resolution cosmological simulations. We employ the highest resolution per Jeans length to date, allowing us to model turbulence on resolved scales, and in addition employ a subgrid scale model for turbulence on unresolved scales. Our findings show that fragmentation occasionally occurs, while central massive objects with ~1000 solar masses still form within 100 AU. The latter may evolve to supermassive stars, which subsequently collapse to massive black holes.
