Primordial black holes in cosmological simulations: growth prospects for supermassive black holes

Lewis R. Prole, John A. Regan, Daxal Mehta +2

It has long been suggested that a fraction of the dark matter in the Universe could exist in the form of primordial black holes (PBHs) that have existed since the radiation dominat…

Heavy Black Hole Seed Formation in High-z Atomic Cooling Halos

Lewis R. Prole, John A. Regan, Simon C. O. Glover +3

Halos with masses in excess of the atomic limit are believed to be ideal environments in which to form heavy black hole seeds with masses above 10^3 Msun. In cases where the H_2 fr…
