Description
The first stars are thought to be extremely luminous and reside in
dark matter halos with masses of approximately a million solar
masses. I will present results from radiation hydrodynamics
simulations that follow the formation of tens of metal-free stars and
their impact on high-redshift galaxy formation and reionization. HII
regions created by the first stars are a few kiloparsecs in radius,
which then overlap with each other and constitute a volume filling
fraction of about a quarter at redshift 15. We also find that the
first galaxies are enriched up to 1/1000th of solar metallicity, which
is sufficient to transition to lower-mass star formation. I will
finish by presenting new results that self-consistently follow the
transition from Pop III to II star formation for the first time.
