Contributed talk
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...

The first burst of star formation in the Universe is thought to give rise to 'massive' stars, with current theory predicting masses in the range 20-150 solar masses. This contrasts with the mode of star formation we see today, which tends to yield stars with masses less than 1 solar mass, and so at some point in the evolution of the Universe there was a transition from primordial (POP III)...

Although the initial strength of magnetic fields is very uncertain, they may have a significant impact on the dynamics in case of dynamo amplification. In this talk, I will review recent work regarding magnetic field amplification during primordial star formation, based on analytic calculations and numerical simulations involving MHD and self-gravity. I will discuss the influence of such...

Over the course of the last decade, a great deal of progress has been made in understanding
the physical processes governing the birth of the first stars and their influence on later epochs
of structure formation. These studies have ignored the possible role of magnetic fields primarily
because the initial field strengths obtained from either cosmological processes like inflation and...
