Open questions in the study of population III star formation
S. C. O. Glover, P. C. Clark, T. H. Greif +4
The first stars were key drivers of early cosmic evolution. We review the main physical elements of the current consensus view, positing that the first stars were predominantly ver…
The formation of the first galaxies and the transition to low-mass star formation
Thomas H. Greif, Dominik R. G. Schleicher, Jarrett L. Johnson +6
The formation of the first galaxies at redshifts z ~ 10-15 signaled the transition from the simple initial state of the universe to one of ever increasing complexity. We here revie…
Chemical mixing in smoothed particle hydrodynamics simulations
Thomas H. Greif, Simon C. O. Glover, Volker Bromm +1
We introduce a simple and efficient algorithm for diffusion in smoothed particle hydrodynamics (SPH) simulations and apply it to the problem of chemical mixing. Based on the concep…
The First Galaxies: Assembly, Cooling and the Onset of Turbulence
Thomas H. Greif, Jarrett L. Johnson, Ralf S. Klessen +1
We investigate the properties of the first galaxies at z > 10 with highly resolved numerical simulations, starting from cosmological initial conditions and taking into account all…
The First Stars
Jarrett L. Johnson, Thomas H. Greif, Volker Bromm
The formation of the first generations of stars at redshifts z > 15-20 signaled the transition from the simple initial state of the universe to one of increasing complexity. We her…
Occurrence of Metal-free Galaxies in the Early Universe
Jarrett L. Johnson, Thomas H. Greif, Volker Bromm
The character of the first galaxies at redshifts z > 10 strongly depends on their level of pre-enrichment, which is in turn determined by the rate of primordial star formation prio…
