Simulation of Primordial Object Formation

We have included the chemical rate network responsible for the formation of molecular hydrogen in the N-body hydrodynamic code, HYDRA, in order to study the formation of the first cosmological objects at redshifts between 10 and 50. We have tested our implementation of the chemical and cooling processes by comparing N-body top-hat simulations with theoretical predictions from a semianalytic model and found them to be in good agreement. We find …
