Supersonic Gas Streams Enhance the Formation of Massive Black Holes in
  the Early Universe
  The origin of super-massive black holes in the early universe remains poorly
understood.Gravitational collapse of a massive primordial gas cloud is a
promising initial process,but theoretical studies have difficulty growing the
black hole fast enough.We report numerical simulations of early black hole
formation starting from realistic cosmological conditions.Supersonic gas
motions left over from the Big Bang prevent early gas cloud formation until
rapid gas condensation is triggered in a proto-galactic halo. A protostar is
formed in the dense, turbulent gas cloud, and it grows by sporadic mass
accretion until it acquires 34,000 solar masses.The massive star ends its life
with a catastrophic collapse to leave a black hole -- a promising seed for the
formation of a monstrous black hole.
