Primordial Star Forming Regions in a CDM Universe
Yu Zhang, Michael L. Norman, Peter Anninos +1
We developed a three-dimensional 2-level hierarchical cosmological code with a realistic and robust treatment of multi-species non-equilibrium ionization and radiative cooling proc…
Cosmological Hydrodynamics with Multi-Species Chemistry and Nonequilibrium Ionization and Cooling
Peter Anninos, Yu Zhang, Tom Abel +1
We have developed a method of solving for multi-species chemical reaction flows in non--equilibrium and self--consistently with the hydrodynamic equations in an expanding FLRW univ…
Modelling Primordial Gas in Numerical Cosmology
T. Abel, P. Anninos, Y. Zhang +1
We have reviewed the chemistry and cooling behaviour of low-density (n<10^4 cm^-3) primordial gas and devised a cooling model wich involves 19 collisional and 9 radiative processes…
How small were the first cosmological objects?
Max Tegmark, Joseph Silk, Martin Rees +3
The minimum mass that a virialized gas cloud must have in order to be able to cool in a Hubble time is computed, using a detailed treatment of the chemistry of molecular hydrogen.…
