Award Description: This project combines observations of the intergalactic medium (IGM) at ultraviolet, optical, and near-infrared frequencies with theoretical and numerical studies of the physics of the IGM and of galaxy formation, and includes forefront numerical simulations in the context of hierarchical clustering cosmologies. Its main goal is to resolve the imprint of galaxies on the IG environment: the radiation, gas, and metals that permeate the universe. As primary research goals, we will: (1) update and extend modeling of the ultraviolet background radiation (UVB), a critical target of, and input to, physical cosmology modeling; (2) constrain UVB models using observations of intergalactic enrichment and helium reionization; (3) observe and model heavy elements at extreme redshifts to constrain the earliest objects responsible for distributing the product of stellar nucleosynthesis, and to assemble a global history of intergalactic enrichment; and (4) observe and characterize the feedback of active galactic nuclei on their intergalactic environment.
