Numerical Simulations of High Redshift Star Formation in Dwarf Galaxies
Konstantinos Tassis, Tom Abel, Greg L. Bryan +1
We present first results from three-dimensional hydrodynamic simulations of the high redshift formation of dwarf galaxies. The simulations use an Eulerian adaptive mesh refinement…
Effects of a Soft X-ray Background on Structure Formation at High Redshift
Marie M. Machacek, Greg L. Bryan, Tom Abel
We use three dimensional hydrodynamic simulations to investigate the effects of a soft X-ray background, that could have been produced by an early generation of mini-quasars, on th…
The Influence of Supershells and Galactic Outflows on the Escape of Ionizing Radiation from Dwarf Starburst Galaxies
Akimi Fujita, Crystal Martin, Mordecai-Mark Mac Low +1
We study the escape of Lyman continuum radiation from the disks of dwarf starburst galaxies, with and without supershells, by solving the radiation transfer problem of stellar radi…
The Nature of the Ionising Background at z=2.5-5
Aaron Sokasian, Tom Abel, Lars E. Hernquist
Using radiative transfer calculations and cosmological simulations of structure formation, we study constraints that can be placed on the nature of the cosmic ultraviolet (UV) back…
The Angular Momentum of Gas in Proto-Galaxies I. Implications for the Formation of Disk Galaxies
Frank C. van den Bosch, Tom Abel, Rupert A. C. Croft +2
We use non-radiative N-body/SPH simulations of structure formation in a LCDM cosmology to compare the angular momentum distributions of dark matter and gas in a large sample of hal…
