The b Distribution of the Lya Forest: Probing Cosmology and the Intergalactic Medium
Greg L. Bryan, Marie E. Machacek
We investigate a method to determine the temperature-density relation of the intergalactic medium (IGM) at z~2-4 using quasar absorption line systems. Using a simple model combined…

Hydrodynamical Simulations of the Lyman Alpha Forest: Model Comparisons
M. E. Machacek, G. L. Bryan, A. Meiksin +4
We investigate the properties of the Lyman alpha forest as predicted by numerical simulations for a range of currently viable cosmological models. This is done in order to understa…

The Lyman Alpha Forest in Hierarchical Cosmologies
M. Machacek, G. Bryan, P. Anninos +3
The comparison of quasar absorption spectra with numerically simulated spectra from hierarchical cosmological models of structure formation promises to be a valuable tool to discri…
